  • Failed to load resource: the server responded with a status of 406 (Not Acceptable)

    - by skip
    I am trying to send json data and get back json data as well. I've <annotation-driven /> configured in my servlet-context.xml and I am using Spring framework version 3.1.0.RELEASE. When I send the request the browser tells me that it is not happy with the data returned from the server and gives me 406 error. And when I see the response from the server I see the whole 406 page returned by tomcat 6 server. I have got following in my pom for Jackson/Jackson processor: <!-- Jackson --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-core-asl</artifactId> <version>1.9.4</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.4</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-xc</artifactId> <version>1.9.4</version> </dependency> <!-- Jackson JSON Processor --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.8.1</version> </dependency> Following is the jquery code I am using to send the json request: $(function(){$(".sutmit-button").click(function(){ var dataString=$("#app-form").serialize(); $.ajax({ type:"POST", url:"apply.json", data:dataString, success:function(data, textStatus, jqXHR){ console.log(jqXHR.status); console.log(data); $('.postcontent').html("<div id='message'></div>"); $('#message').html("<h3>Request Submitted</h3>").append("<p>Thank you for submiting your request.</p>").hide().fadeIn(1500,function(){$('#message');}); }, error:function(jqXHR, textStatus, errorThrown) { console.log(jqXHR.status); $('.postcontent').html("<div id='message'></div>"); $('#message').html("<h3>Request failed.</h3>").hide().fadeIn(1500,function(){$('#message');}); }, dataType: "json" }); return false;});}); Following is the Controller that is handling the request: @RequestMapping(method = RequestMethod.POST, value="apply", headers="Accept=application/json") public @ResponseBody Application processFranchiseeApplicationForm(HttpServletRequest request) { //...

Could someone help me understand why am I getting the given error? Thanks.

  • Make wix installation set upgrade to same folder

    - by Magnus Akselvoll
    How can I make a major upgrade to an installation set (MSI) built with Wix install into the same folder as the original installation? The installation is correctly detected as an upgrade, but the directory selection screen is still shown and with the default value (not necessarily the current installation folder). Do I have to do manual work like saving the installation folder in a registry key upon first installing and then read this key upon upgrade? If so, is there any example? Or is there some easier way to achieve this in MSI / Wix? As reference I paste in my current Wix file below: <?xml version="1.0" encoding="utf-8"?> <!-- Package information --> <Package Keywords="Installer" Id="e85e6190-1cd4-49f5-8924-9da5fcb8aee8" Description="Installs MyCompany Integration Framework 1.0.0" Comments="Installs MyCompany Integration Framework 1.0.0" InstallerVersion="100" Compressed="yes" /> <Upgrade Id='9071eacc-9b5a-48e3-bb90-8064d2b2c45d'> <UpgradeVersion Property="PATCHFOUND" OnlyDetect="no" Minimum="0.0.1" IncludeMinimum="yes" Maximum="1.0.0" IncludeMaximum="yes"/> </Upgrade> <!-- Useless but necessary... --> <Media Id="1" Cabinet="MyCompany.cab" EmbedCab="yes" /> <!-- Precondition: .Net 2 must be installed --> <Condition Message='This setup requires the .NET Framework 2 or higher.'> <![CDATA[MsiNetAssemblySupport >= "2.0.50727"]]> </Condition> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="MyCompany" Name="MyCompany"> <Directory Id="INSTALLDIR" Name="Integrat" LongName="MyCompany Integration Framework"> <Component Id="MyCompanyDllComponent" Guid="4f362043-03a0-472d-a84f-896522ce7d2b" DiskId="1"> <File Id="MyCompanyIntegrationDll" Name="IbIntegr.dll" src="..\Build\MyCompany.Integration.dll" Vital="yes" LongName="MyCompany.Integration.dll" /> <File Id="MyCompanyServiceModelDll" Name="IbSerMod.dll" src="..\Build\MyCompany.ServiceModel.dll" Vital="yes" LongName="MyCompany.ServiceModel.dll" /> </Component> <!-- More components --> </Directory> </Directory> </Directory> <Feature Id="MyCompanyProductFeature" Title='MyCompany Integration Framework' Description='The complete package' Display='expand' Level="1" InstallDefault='local' ConfigurableDirectory="INSTALLDIR"> <ComponentRef Id="MyCompanyDllComponent" /> </Feature> <!-- Task scheduler application.

  • Why doesn't the default model binder update my partial view model on postback?

    - by bdnewbe
    I have a class that contains another class as one of its properties. public class SiteProperties { public SiteProperties() { DropFontFamily = "Arial, Helvetica, Sans-serif"; } public string DropFontFamily { get; set; } private ResultPageProperties m_ResultPagePropertyList; public ResultPageProperties ResultPagePropertyList { get { if (m_ResultPagePropertyList == null) m_ResultPagePropertyList = new ResultPageProperties(); return m_ResultPagePropertyList; } set { m_ResultPagePropertyList = value; } } } The second class has just one property public class ResultPageProperties { public ResultPageProperties() { ResultFontFamily = "Arial, Helvetica, Sans-serif"; } public string ResultFontFamily { get; set; } } My controller just grabs the SiteProperties and returns the view. On submit, it accepts SiteProperties and returns the same view. public class CompanyController : Controller { public ActionResult SiteOptions(int id) { SiteProperties site = new SiteProperties(); PopulateProperyDropDownLists(); return View("SiteOptions", site); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult SiteOptions(SiteProperties properties) { PopulateProperyDropDownLists(); return View("SiteOptions", properties); } private void PopulateProperyDropDownLists() { var fontFamilyList = new List<SelectListItem>(); fontFamilyList.Add(new SelectListItem() { Text = "Arial, Helvetica, Sans-serif", Value = "Arial, Helvetica, Sans-serif" }); fontFamilyList.Add(new SelectListItem() { Text = "Times New Roman, Times, serif", Value = "Times New Roman, Times, serif" }); fontFamilyList.Add(new SelectListItem() { Text = "Courier New, Courier, Monospace", Value = "Courier New, Courier, Monospace" }); ViewData["FontFamilyList"] = fontFamilyList; } } The view contains a partial view that renders the ResultPageProperties Model. <% using (Html.BeginForm("SiteOptions", "Company", FormMethod.Post)) {%> <p><input type="submit" value="Submit" /></p> <div>View level input</div> <div> <label>Font family</label><br /> <%= Html.DropDownListFor(m => m.DropFontFamily, ViewData["FontFamilyList"] as List<SelectListItem>, new { Class = "UpdatesDropDownExample" })%> </div> <% Html.RenderPartial("ResultPagePropertyInput", Model.ResultPagePropertyList); %> <% } %> The partial is just <div style='margin-top: 1em;'>View level input</div> <div> <label>Font family</label><br /> <%= Html.DropDownListFor(m => m.ResultFontFamily, ViewData["FontFamilyList"] as List<SelectListItem>, new { Class = "UpdatesResultPageExample" })%> </div> OK, so when the page renders, you get "Arial, ..." in both selects. If you choose another option for both and click submit, the binder populates the SiteProperties object and passes it to the controller. However, the ResultFontFamily always contains the original value. I was expecting it to have the value the user selected. What am I missing?

  • Showing updated content on the client

    Hi, I have a file on server which is viewed by the client asynchronously as and when required . The file is going to get modified on server side . Also updates are reflected in browser also In my views.py the code is : def showfiledata(request): somecommand ="ls -l > /home/tazim/webexample/templates/tmp.txt" with open("/home/tazim/webexample/templates/tmp.txt") as f: read_data = f.read() f.closed return_dict = {'filedata':read_data} json = simplejson.dumps(return_dict) return HttpResponse(json,mimetype="application/json") Here, entire file is sent every time client requests for the file data .Instead I want that only modified data sholud be received since sending entire file is not feasible if file size is large .

  • How can i optimize this recursive method

    - by Tirdyr
    Hi there. I'm trying to make a word puzzle game, and for that i'm using a recursive method to find all possible words in the given letters. The letters is in a 4x4 board. Like this: ABCD EFGH HIJK LMNO The recursive method is called inside this loop: for (int y = 0; y < width; y++) { for (int x = 0; x < height; x++) { myScabble.Search(letters, y, x, width, height, "", covered, t); } } letters is a 2D array of chars. y & x is ints that shows where in the board width & height is also int, that tells the dimensions of the board "" is the string we are trying to make (the word) covered is an array of bools, to check if we allready used that square. t is a List (wich contains all the words to check against). The recursive method that need optimizing: public void Search(char[,] letters, int y, int x, int width, int height, string build, bool[,] covered, List<aWord> tt) { // Dont get outside the bounds if (y >= width || y < 0 || x >= height || x < 0) { return; } // Dont deal with allrady covered squares if (covered[x, y]) { return; } // Get Letter char letter = letters[x, y]; // Append string pass = build + letter; // check if its a possibel word //List<aWord> t = myWords.aWord.Where(w => w.word.StartsWith(pass)).ToList(); List<aWord> t = tt.Where(w => w.word.StartsWith(pass)).ToList(); // check if the list is emphty if (t.Count < 10 && t.Count != 0) { //stop point } if (t.Count == 0) { return; } // Check if its a complete word. if (t[0].word == pass) { //check if its allrdy present in the _found dictinary if (!_found.ContainsKey(pass)) { //if not add the word to the dictionary _found.Add(pass, true); } } // Check to see if there is more than 1 more that matches string pass // ie. are there more words to find. if (t.Count > 1) { // make a copy of the covered array bool[,] cov = new bool[height, width]; for (int i = 0; i < width; i++) { for (int a = 0; a < height; a++) { cov[a, i] = covered[a, i]; } } // Set the current square as covered. cov[x, y] = true; // Continue in all 8 directions. Search(letters, y + 1, x, width, height, pass, cov, t); Search(letters, y, x + 1, width, height, pass, cov, t); Search(letters, y + 1, x + 1, width, height, pass, cov, t); Search(letters, y - 1, x, width, height, pass, cov, t); Search(letters, y, x - 1, width, height, pass, cov, t); Search(letters, y - 1, x - 1, width, height, pass, cov, t); Search(letters, y - 1, x + 1, width, height, pass, cov, t); Search(letters, y + 1, x - 1, width, height, pass, cov, t); } } The code works as i expected it to do, however it is very slow.. it takes about 2 mins to find the words. EDIT: i clarified that the letters array is 2D

  • Update transaction in SQL Server 2008 R2 from ASP.Net not working

    - by Amarus
    Hello! Even though I've been a stalker here for ages, this is the first post I'm making. Hopefully, it won't end here and more optimistically future posts might actually be me trying to give a hand to someone else, I do owe this community that much and more. Now, what I'm trying to do is simple and most probably the reason behind it not working is my own stupidity. However, I'm stumped here. I'm working on an ASP.Net website that interacts with an SQL Server 2008 R2 database. So far everything has been going okay but updating a row (or more) just won't work. I even tried copying and pasting code from this site and others but it's always the same thing. In short: No exception or errors are shown when the update command executes (it even gives the correct count of affected rows) but no changes are actually made on the database. Here's a simplified version of my code (the original had more commands and tons of parameters each, but even when it's like this it doesn't work): protected void btSubmit_Click(object sender, EventArgs e) { using (SqlConnection connection = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString)) { string commandString = "UPDATE [impoundLotAlpha].[dbo].[Vehicle]" + "SET [VehicleMake] = @VehicleMake" + " WHERE [ComplaintID] = @ComplaintID"; using (SqlCommand command = new SqlCommand(commandString, connection)) { SqlTransaction transaction = null; try { command.Connection.Open(); transaction = connection.BeginTransaction(IsolationLevel.Serializable); command.Transaction = transaction; SqlParameter complaintID = new SqlParameter("@complaintID", SqlDbType.Int); complaintID.Value = HttpContext.Current.Request.QueryString["complaintID"]; command.Parameters.Add(complaintID); SqlParameter VehicleMake = new SqlParameter("@VehicleMake", SqlDbType.VarChar, 20); VehicleMake.Value = tbVehicleMake.Text; command.Parameters.Add(VehicleMake); command.ExecuteNonQuery(); transaction.Commit(); } catch { transaction.Rollback(); throw; } finally { connection.Close(); } } } } I've tried this with the "SqlTransaction" stuff and without it and nothing changes. Also, since I'm doing multiple updates at once, I want to have them act as a single transaction. I've found that it can be either done like this or by use of the classes included in the System.Transactions namespace (CommittableTransaction, TransactionScope...). I tried all I could find but didn't get any different results. The connection string in web.config is as follows: <connectionStrings> <add name="ApplicationServices" connectionString="Data Source=localhost;Initial Catalog=ImpoundLotAlpha;Integrated Security=True" providerName="System.Data.SqlClient"/> </connectionStrings> So, tldr; version: What is the mistake that I did with that record update attempt? (Figured it out, check below if you're having a similar issue.) What is the best method to gather multiple update commands as a single transaction? Thanks in advance for any kind of help and/or suggestions! Edit: It seems that I was lacking some sleep yesterday cause this time it only took me 5 minutes to figure out my mistake. Apparently the update was working properly but I failed to notice that the textbox values were being overwritten in Page_Load. For some reason I had this part commented: if (IsPostBack) return; The second part of the question still stands. But should I post this as an answer to my own question or keep it like this?

  • piecing together a jquery form mailer

    - by Joel
    Hi guys, My newbieness is shining through here...I managed to piece together a form mailer that works great, but now I need to add two more fields, and I'm at a loss as to how to do it. Over the months, I have commented out some things I didn't need, but now I'm stuck. I borrowed from this tutorial to make the original form: http://trevordavis.net/blog/tutorial/ajax-forms-with-jquery/ But then I cannibalized it to make an email signup form for a newsletter, so the fields I need are: recipient email (me-hard coded in) senders email address subject (hardcoded in) first name and city in the body of the message For my form, I have this: <div> <?php include('verify.php'); ?> <form action="index_success.php" method="post" id="sendEmail" class="email"> <h3 class="register2">Newsletter Signup:</h3> <ul class="forms email"> <li class="name"><label for="yourName">Name: </label> <input type="text" name="yourName" class="info" id="yourName" value=" " /><br> </li> <li class="city"><label for="yourCity">City: </label> <input type="text" name="yourCity" class="info" id="yourCity" value=" " /><br> </li> <li class="email"><label for="emailFrom">Email: </label> <input type="text" name="emailFrom" class="info" id="emailFrom" value="<?= $_POST['emailFrom']; ?>" /> <?php if(isset($emailFromError)) echo '<span class="error">'.$emailFromError.'</span>'; ?> </li> <li class="buttons email"> <button type="submit" id="submit">Send</button> <input type="hidden" name="submitted" id="submitted" value="true" /> </li> </ul> </form> </div> emailcontact.js: $(document).ready(function(){ $("#submit").click(function(){ $(".error").hide(); var hasError = false; var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/; var emailFromVal = $("#emailFrom").val(); if(emailFromVal == '') { $("#emailFrom").after('<span class="error">You forgot to enter the email address to send from.</span>'); hasError = true; } else if(!emailReg.test(emailFromVal)) { $("#emailFrom").after('<span class="error">Enter a valid email address to send from.</span>'); hasError = true; } var subjectVal = $("#subject").val(); if(subjectVal == '') { $("#subject").after('<span class="error">You forgot to enter your name.</span>'); hasError = true; } var messageVal = $("#message").val(); if(messageVal == '') { $("#message").after('<span class="error">You forgot to enter your city.</span>'); hasError = true; } if(hasError == false) { $(this).hide(); $("#sendEmail li.buttons").append('<img src="/wp-content/themes/default/images/template/loading.gif" alt="Loading" id="loading" />'); $.post("/includes/sendemail.php", //emailTo: emailToVal, { emailFrom: emailFromVal, subject: subjectVal, message: messageVal }, function(data){ $("#sendEmail").slideUp("normal", function() { $("#sendEmail").before('<h3 class="register2">Success!</h3><p class="emailbox">You are on the Newsletter email list.</p>'); }); } ); } return false; }); }); sendmail.php: <?php $mailTo = $_POST['emailTo']; $mailFrom = $_POST['emailFrom']; $subject = $_POST['yourName']; $message = $_POST['yourCity']; mail('[email protected]','Rattletree Newsletter', 'Name='.$subject.

  • Please clarify how create/update happens against child entities of an aggregate root

    - by christian
    After much reading and thinking as I begin to get my head wrapped around DDD, I am a bit confused about the best practices for dealing with complex hierarchies under an aggregate root. I think this is a FAQ but after reading countless examples and discussions, no one is quite talking about the issue I'm seeing. If I am aligned with the DDD thinking, entities below the aggregate root should be immutable. This is the crux of my trouble, so if that isn't correct, that is why I'm lost. Here is a fabricated example...hope it holds enough water to discuss. Consider an automobile insurance policy (I'm not in insurance, but this matches the language I hear when on the phone w/ my insurance company). Policy is clearly an entity. Within the policy, let's say we have Auto. Auto, for the sake of this example, only exists within a policy (maybe you could transfer an Auto to another policy, so this is potential for an aggregate as well, which changes Policy...but assume it simpler than that for now). Since an Auto cannot exist without a Policy, I think it should be an Entity but not a root. So Policy in this case is an aggregate root. Now, to create a Policy, let's assume it has to have at least one auto. This is where I get frustrated. Assume Auto is fairly complex, including many fields and maybe a child for where it is garaged (a Location). If I understand correctly, a "create Policy" constructor/factory would have to take as input an Auto or be restricted via a builder to not be created without this Auto. And the Auto's creation, since it is an entity, can't be done beforehand (because it is immutable? maybe this is just an incorrect interpretation). So you don't get to say new Auto and then setX, setY, add(Z). If Auto is more than somewhat trivial, you end up having to build a huge hierarchy of builders and such to try to manage creating an Auto within the context of the Policy. One more twist to this is later, after the Policy is created and one wishes to add another Auto...or update an existing Auto. Clearly, the Policy controls this...fine...but Policy.addAuto() won't quite fly because one can't just pass in a new Auto (right!?). Examples say things like Policy.addAuto(VIN, make, model, etc.) but are all so simple that that looks reasonable. But if this factory method approach falls apart with too many parameters (the entire Auto interface, conceivably) I need a solution. From that point in my thinking, I'm realizing that having a transient reference to an entity is OK. So, maybe it is fine to have a entity created outside of its parent within the aggregate in a transient environment, so maybe it is OK to say something like: auto = AutoFactory.createAuto(); auto.setX auto.setY or if sticking to immutability, AutoBuilder.new().setX().setY().build() and then have it get sorted out when you say Policy.addAuto(auto) This insurance example gets more interesting if you add Events, such as an Accident with its PolicyReports or RepairEstimates...some value objects but most entities that are all really meaningless outside the policy...at least for my simple example. The lifecycle of Policy with its growing hierarchy over time seems the fundamental picture I must draw before really starting to dig in...and it is more the factory concept or how the child entities get built/attached to an aggregate root that I haven't seen a solid example of. I think I'm close. Hope this is clear and not just a repeat FAQ that has answers all over the place.

  • HTML/JS/CSS issue getting bigger by itself

    - by Azzyh
    Here's the picture to begin with. I have this check box, that when you check, then with jQuery toggle(); it hides that you see in first half of the picture (#writeComment) and shows #SCtryVOTE (what you see in the other half picture, to the right). Now i dont know why but of some reason it expands when its checked, why i dont know, is it because it needs more place than it have or? how do i make this work without having problems when its checked. Here's coding: $('#tryout').click(function () { $('#writeComment').toggle(!$(this).attr('checked')); $('#SCtryVOTE').toggle($(this).attr('checked')); }); the js jquery script part, heres the table and divs HTML part: <input type="checkbox" id="tryout"> <table align="center" width="400" cellpadding="0" cellspacing="1" id="theBoxer"> <tr style="background: #686868;"> <td align="center" valign="top" width="70" height="25" style="border:1px #FFF solid;">Opret</td> <td align="center" valign="top" width="70" height="25" style="border:1px #FFF solid;">Opret</td> </td> </tr> <tr> <td align="left" valign="top" width="70" height="112" style=""> TEST </td> <td align="left" valign="top" width="70" height="112" style=""> <div id="writeComment"> Smid en kommentar:<br> <form action="javascript:DoInsert()" method="post"> <textarea id="kommentar" name="kommentar"></textarea><br /> <input type="hidden" name="fID" id="fID" value="<? echo $_GET["id"]; ?>"> <input type="submit" name="Submit" value="Sæt ind!"> </form> </div> <div id="SCtryVOTE" style="display: none;"> <form onsubmit="if (!this.comment.cleared) clearContents( document.getElementById('comment') ); return true;" action="javascript:DoSCInsert()" method="post"> <textarea onfocus=" javascript:clearContents(this); this.cleared=true;" rows="5" cols="40" id="comment" name="comment" <?php if($vis["username"] == $pusername) { echo "DISABLED"; } ?>>Tryk for at skrive.

  • Handling a Long Running jsp request on the server using Ajax and threads

    - by John Blue
    I am trying to implement a solution for a long running process on the server where it is taking about 10 min to process a pdf generation request. The browser bored/timesout at the 5 mins. I was thinking to deal with this using a Ajax and threads. I am using regular javascript for ajax. But I am stuck with it. I have reached till the point where it sends the request to the servlet and the servlet starts the thread.Please see the below code public class HelloServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet { protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("POST request!!"); LongProcess longProcess = new LongProcess(); longProcess.setDaemon(true); longProcess.start(); request.getSession().setAttribute("longProcess", longProcess); request.getRequestDispatcher("index.jsp").forward(request, response); } } class LongProcess extends Thread { public void run() { System.out.println("Thread Started!!"); while (progress < 10) { try { sleep(2000); } catch (InterruptedException ignore) {} progress++; } } } Here is my AJax call <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>My Title</title> <script language="JavaScript" > function getXMLObject() //XML OBJECT { var xmlHttp = false; xmlHttp = new XMLHttpRequest(); //For Mozilla, Opera Browsers return xmlHttp; // Mandatory Statement returning the ajax object created } var xmlhttp = new getXMLObject(); //xmlhttp holds the ajax object function ajaxFunction() { xmlhttp.open("GET","HelloServlet" ,true); xmlhttp.onreadystatechange = handleServerResponse; xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xmlhttp.send(null); } function handleServerResponse() { if (xmlhttp.readyState == 4) { if(xmlhttp.status == 200) { document.forms[0].myDiv.value = xmlhttp.responseText; setTimeout(ajaxFunction(), 2000); } else { alert("Error during AJAX call. Please try again"); } } } function openPDF() { document.forms[0].method = "POST"; document.forms[0].action = "HelloServlet"; document.forms[0].submit(); } function stopAjax(){ clearInterval(intervalID); } </script> </head> <body><form name="myForm"> <table><tr><td> <INPUT TYPE="BUTTON" NAME="Download" VALUE="Download Queue ( PDF )" onclick="openPDF();"> </td></tr> <tr><td> Current status: <div id="myDiv"></div>% </td></tr></table> </form></body></html> But I dont know how to proceed further like how will the thread communicate the browser that the process has complete and how should the ajax call me made and check the status of the request. Please let me know if I am missing some pieces. Any suggestion if helpful.

  • Form submission info showing up in URL and not working

    - by kcurtin
    I am making a Rails 3.1 app and have a signup form that was working fine, but I seemed to have changed something to break it.. I'm using Twitter bootstrap and twitter_bootstrap_form_for gem. I made some change that messed with the formatting of the form fields, but more importantly, when I submit the Sign Up form to create a new User, the information is showing up in the URL and looks like this: EDIT: This is happening in the latest versions of Chrome and Firefox http://localhost:3000/?utf8=%E2%9C%93&authenticity_token=UaKG5Y8fuPul2Klx7e2LtdPLTRepBxDM3Zdy8S%2F52W4%3D&user%5Bemail%5D=kevinc%40example.com&user%5Bpassword%5D=testing&user%5Bpassword_confirmation%5D=testing&commit=Sign+Up Here is the code for the form: <div class="span7"> <h3 class="center" id="more">Sign Up Now!</h3> <%= twitter_bootstrap_form_for @user do |user| %> <%= user.email_field :email, :placeholder => '[email protected]' %> <%= user.password_field :password %> <%= user.password_field :password_confirmation, 'Confirm Password' %> <%= user.actions do %> <%= user.submit 'Sign Up' %> <% end %> <% end %> </div> Here is the code for the UsersController: class UsersController < ApplicationController def new @user = User.new end def create @user = User.new(params[:user]) if @user.save redirect_to about_path, :notice => "Signed up!" else render 'new' end end end Not sure if there is more you need but if so let me know! Thank you! Edit: For debugging I tried specifying :post and also using a plain form_for <%= form_for(@user, :method => :post) do |f| %> <div class="field"> <%= f.label :email %> <%= f.email_field :email %> </div> <div class="field"> <%= f.label :password %> <%= f.password_field :password %> </div> <div class="field"> <%= f.label :password_confirmation %> <%= f.password_field :password_confirmation %> </div> <div class="actions"><%= f.submit "Sign Up" %></div> <% end %> This gives me the same problem as above. Adding routes.rb: Auth31::Application.routes.draw do get "home" => "pages#home" get "about" => "pages#about" get "contact" => "pages#contact" get "help" => "pages#help" get "login" => "sessions#new", :as => "login" get "logout" => "sessions#destroy", :as => "logout" get "signup" => "users#new", :as => "signup" root :to => "pages#home" resources :pages resources :users resources :sessions resources :password_resets end

  • Generating strongly biased radom numbers for tests

    - by nobody
    I want to run tests with randomized inputs and need to generate 'sensible' random numbers, that is, numbers that match good enough to pass the tested function's preconditions, but hopefully wreak havoc deeper inside its code. math.random() (I'm using Lua) produces uniformly distributed random numbers. Scaling these up will give far more big numbers than small numbers, and there will be very few integers. I would like to skew the random numbers (or generate new ones using the old function as a randomness source) in a way that strongly favors 'simple' numbers, but will still cover the whole range, I.e. extending up to positive/negative infinity (or ±1e309 for double). This means: numbers up to, say, ten should be most common, integers should be more common than fractions, numbers ending in 0.5 should be the most common fractions, followed by 0.25 and 0.75; then 0.125, and so on. A different description: Fix a base probability x such that probabilities will sum to one and define the probability of a number n as xk where k is the generation in which n is constructed as a surreal number1. That assigns x to 0, x2 to -1 and +1, x3 to -2, -1/2, +1/2 and +2, and so on. This gives a nice description of something close to what I want (it skews a bit too much), but is near-unusable for computing random numbers. The resulting distribution is nowhere continuous (it's fractal!), I'm not sure how to determine the base probability x (I think for infinite precision it would be zero), and computing numbers based on this by iteration is awfully slow (spending near-infinite time to construct large numbers). Does anyone know of a simple approximation that, given a uniformly distributed randomness source, produces random numbers very roughly distributed as described above? I would like to run thousands of randomized tests, quantity/speed is more important than quality. Still, better numbers mean less inputs get rejected. Lua has a JIT, so performance can't be reasonably predicted. Jumps based on randomness will break every prediction, and many calls to math.random() will be slow, too. This means a closed formula will be better than an iterative or recursive one. 1 Wikipedia has an article on surreal numbers, with a nice picture. A surreal number is a pair of two surreal numbers, i.e. x := {n|m}, and its value is the number in the middle of the pair, i.e. (for finite numbers) {n|m} = (n+m)/2 (as rational). If one side of the pair is empty, that's interpreted as increment (or decrement, if right is empty) by one. If both sides are empty, that's zero. Initially, there are no numbers, so the only number one can build is 0 := { | }. In generation two one can build numbers {0| } =: 1 and { |0} =: -1, in three we get {1| } =: 2, {|1} =: -2, {0|1} =: 1/2 and {-1|0} =: -1/2 (plus some more complex representations of known numbers, e.g. {-1|1} ? 0). Note that e.g. 1/3 is never generated by finite numbers because it is an infinite fraction – the same goes for floats, 1/3 is never represented exactly.

  • HMTL5 Anti Aliasing Browser Disable

    - by Tappa Tappa
    I am forced to consider writing a library to handle the fundamental basics of drawing lines, thick lines, circles, squares etc. of an HTML5 canvas because I can't disable a feature embedded in the browser rendering of the core canvas algorithms. Am I forced to build the HTML5 Canvas rendering process from the ground up? If I am, who's in with me to do this? Who wants to change the world? Imagine a simple drawing application written in HTML5... you draw a shape... a closed shape like a rudimentary circle, free hand, more like an onion than a circle (well, that's what mine would look like!)... then imagine selecting a paint bucket icon and clicking inside that shape you drew and expecting it to be filled with a color of your choice. Imagine your surprise as you selected "Paint Bucket" and clicked in the middle of your shape and it filled your shape with color... BUT, not quite... HANG ON... this isn't right!!! On the inside of the edge of the shape you drew is a blur between the background color and your fill color and the edge color... the fill seems to be flawed. You wanted a straight forward "Paint Bucket" / "Fill"... you wanted to draw a shape and then fill it with a color... no fuss.... fill the whole damned inside of your shape with the color you choose. Your web browser has decided that when you draw the lines to define your shape they will be anti-aliased. If you draw a black line for your shape... well, the browser will draw grey pixels along the edges, in places... to make it look like a "better" line. Yeah, a "better" line that **s up the paint / flood fill process. How much does is cost to pay off the browser developers to expose a property to disable their anti-aliasing rendering? Disabling would save milliseconds for their rendering engine, surely! Bah, I really don't want to have to build my own canvas rendering engine using Bresenham line rendering algorithm... WHAT CAN BE DONE... HOW CAN THIS BE CHANGED!!!??? Do I need to start a petition aimed at the WC3???? Will you include your name if you are interested??? UPDATED function DrawLine(objContext, FromX, FromY, ToX, ToY) { var dx = Math.abs(ToX - FromX); var dy = Math.abs(ToY - FromY); var sx = (FromX < ToX) ? 1 : -1; var sy = (FromY < ToY) ? 1 : -1; var err = dx - dy; var CurX, CurY; CurX = FromX; CurY = FromY; while (true) { objContext.fillRect(CurX, CurY, objContext.lineWidth, objContext.lineWidth); if ((CurX == ToX) && (CurY == ToY)) break; var e2 = 2 * err; if (e2 > -dy) { err -= dy; CurX += sx; } if (e2 < dx) { err += dx; CurY += sy; } } }

  • PHP setting cookies in a child class

    - by steve
    I am writing a custom session handler and for the life of me I cannot get a cookie to set in it. I'm not outputting anything to the browser before I set the cookie but it still doesn't work. Its killing me. The cookie will set if I set it in the script I define and call on the session handler with. If necessary I will post code. Any ideas people? <?php /* require the needed classes comment out what is not needed */ require_once("classes/sessionmanager.php"); require_once("classes/template.php"); require_once("classes/database.php"); $title=" "; //titlebar of the web browser $description=" "; $keywords=" "; //meta keywords $menutype="default"; //default or customer, customer is elevated $pagetitle="dflsfsf "; //title of the webpage $pagebody=" "; //body of the webpage $template=template::def_instance(); $database=database::def_instance(); $session=sessionmanager::def_instance(); $session->sessions(); session_start(); ?> and this is the one that actually sets the cookie for the session function write($session_id,$session_data) { $session_id = mysql_real_escape_string($session_id); $session_data = mysql_real_escape_string(serialize($session_data)); $expires = time() + 3600; $user_ip = $_SERVER['REMOTE_ADDR']; $bol = FALSE; $time = time(); $newsession = FALSE; $auth = FALSE; $query = "SELECT * FROM 'sessions' WHERE 'expires' > '$time'"; $sessions_result = $this->query($query); $newsession = $this->newsession_check($session_id,$sessions_result); while($sessions_array = mysql_fetch_array($sessions_result) AND $auth = FALSE) { $session_array = $this->strip($session_array); $auth = $this->auth_check($session_array,$session_id); } /* this is an authentic session. build queries and update it */ if($auth = TRUE AND $newsession = FALSE) { $session_data = mysql_real_escape_string($session_data); $update_query1 = "UPDATE 'sessions' SET 'user_ip' = '$user_ip' WHERE 'session_id' = '$session_id'"; $update_query2 = "UPDATE 'sessions' SET 'data' = '$session_data' WHERE 'session_id = '$session_id'"; $update_query3 = "UPDATE 'sessions' SET 'expires' = '$expires' WHERE 'session_id' = '$session_id'"; $this->query($update_query1); $this->query($update_query2); $this->query($update_query3); $bol = TRUE; } elseif($newsession = TRUE) { /* this is a new session, build and create it */ $random_number = $this->obtain_random(); $cookieval = hash("sha512",$random_number); setcookie("rndn",$cookieval); $query = "INSERT INTO sessions VALUES('$session_id','0','$user_ip','$random_number','$session_data','$expires')"; $this->query($query); //echo $cookieval."this is the cookie <<"; $bol = TRUE; } return $bol; }

  • Double Linked List header node keeps returning first value as 0

    - by Craig
    I will preface to say that this is my first question. I am currently getting my Masters degree in Information Security and I had to take C++ programming this semester. So this is homework related. I am not looking for you to answer my homework but I am running into a peculiar situation. I have created the program to work with a doubly linked list and everything works fine. However when I have the user create a list of values the first node keeps returning 0. I have tried finding some reading on this and I cannot locate any reference to it. My question is then is the header node(first node) always going to be zero? Or am I doing something wrong. case: 'C': cout<<"Please enter a list:"<<endl; while(n!=-999){ myList.insert(n); cin>> n;} break; I now enter: 12321, 1234,64564,346346. The results in 0, 12321, 1234, 64564,346346. Is this what should happen or am I doing something wrong? Also as this is my first post please feel free to criticize or teach me how to color code the keywords. Anyway this is a homework assignment so I am only looking for guidance and constructive criticism. Thank you all in advance So I cannot figure out the comment sections on this forum so I will edit the original post The first section is the constructor code: template <class Type> doublyLinkedList<Type>::doublyLinkedList() { first= NULL; last = NULL; count = 0; } Then there is my insert function : template <class Type> void doublyLinkedList<Type>::insert(const Type& insertItem) { nodeType<Type> *current; //pointer to traverse the list nodeType<Type> *trailCurrent; //pointer just before current nodeType<Type> *newNode; //pointer to create a node bool found; newNode = new nodeType<Type>; //create the node newNode->info = insertItem; //store the new item in the node newNode->next = NULL; newNode->back = NULL; if(first == NULL) //if the list is empty, newNode is //the only node { first = newNode; last = newNode; count++; } else { found = false; current = first; while (current != NULL && !found) //search the list if (current->info >= insertItem) found = true; else { trailCurrent = current; current = current->next; } if (current == first) //insert newNode before first { first->back = newNode; newNode->next = first; first = newNode; count++; } else { //insert newNode between trailCurrent and current if (current != NULL) { trailCurrent->next = newNode; newNode->back = trailCurrent; newNode->next = current; current->back = newNode; } else { trailCurrent->next = newNode; newNode->back = trailCurrent; last = newNode; } count++; }//end else }//end else }//end Then I have an initialization function too: template <class Type> void doublyLinkedList<Type>::initializeList() { destroy(); } Did I miss anything?

  • Can someone help me compare using F# over C# in this specific example (IP Address expressions)?

    - by Phobis
    So, I am writing code to parse and IP Address expression and turn it into a regular expression that could be run against and IP Address string and return a boolean response. I wrote the code in C# (OO) and it was 110 lines of code. I am trying to compare the amount of code and the expressiveness of C# to F# (I am a C# programmer and a noob at F#). I don't want to post both the C# and F#, just because I don't want to clutter the post. If needed, I will do so. Anyway, I will give an example. Here is an expression: 192.168.0.250,244-248,108,51,7;127.0.0.1 I would like to take that and turn it into this regular expression: ((192.168.0.(250|244|245|246|247|248|108|51|7))|(127.0.0.1)) Here are some steps I am following: Operations: Break by ";" 192.168.0.250,244-248,108,51,7 127.0.0.1 Break by "." 192 168 0 250,244-248,108,51,7 Break by "," 250 244-248 108 51 7 Break by "-" 244 248 I came up with F# that produces the output. I am trying to forward-pipe through my operations listed above, as I think that would be more expressive. Can anyone make this code better? Teach me something :) open System let createItemArray (group:bool) (y:char) (items:string[]) = [| let indexes = items.Length - 1 let group = indexes > 0 && group if group then yield "(" for i in 0 .. indexes do yield items.[i].ToString() if i < indexes then yield y.ToString() if group then yield ")" |] let breakBy (group:bool) (x:string) (y:char): string[] = x.Split(y) |> createItemArray group y let breakItem (x:string) (y:char): string[] = breakBy false x y let breakGroup (x:string) (y:char): string[] = breakBy true x y let AddressExpression address:string = let builder = new System.Text.StringBuilder "(" breakGroup address ';' |> Array.collect (fun octet -> breakItem octet '.') |> Array.collect (fun options -> breakGroup options ',') |> Array.collect (fun (ranges : string) -> match (breakGroup ranges '-') with | x when x.Length > 3 -> match (Int32.TryParse(x.[1]), Int32.TryParse(x.[3])) with | ((true, a) ,(true, b)) -> [|a .. b|] |> Array.map (int >> string) |> createItemArray false '-' | _ -> [|ranges|] | _ -> [|ranges|] ) |> Array.iter (fun item -> match item with | ";" -> builder.Append ")|(" | "." -> builder.Append "\." | "," | "-" -> builder.Append "|" | _ -> builder.Append item |> ignore ) builder.Append(")").ToString() let address = "192.168.0.250,244-248,108,51,7;127.0.0.1" AddressExpression address

  • Split a Large File In C++

    - by wdow88
    Hey all, I'm trying to write a program that takes a large file (of any time) and splits it into many smaller "chunks". I think I have the basic idea down, but for some reason I cannot create a chunk size over 12,000 bites. I know there are a few solutions on google, etc. but I am more interested in learning what the origin of this limitation is then actually using the program to split files. //This file splits are larger into smaller files of a user inputted size. #include<iostream> #include<fstream> #include<string> #include<sstream> #include <direct.h> #include <stdlib.h> using namespace std; void GetCurrentPath(char* buffer) { _getcwd(buffer, _MAX_PATH); } int main() { // use the function to get the path char CurrentPath[_MAX_PATH]; GetCurrentPath(CurrentPath);//Get the current directory (used for displaying output) fstream bigFile; string filename; int partsize; cout << "Enter a file name: "; cin >> filename; //Recieve target file cout << "Enter the number of bites in each smaller file: "; cin >> partsize; //Recieve volume size bigFile.open(filename.c_str(),ios::in | ios::binary); bigFile.seekg(0, ios::end); // position get-ptr 0 bytes from end int size = bigFile.tellg(); // get-ptr position is now same as file size bigFile.seekg(0, ios::beg); // position get-ptr 0 bytes from beginning for (int i = 0; i <= (size / partsize); i++) { //Build File Name string partname = filename; //The original filename string charnum; //archive number stringstream out; //stringstream object out, used to build the archive name out << "." << i; charnum = out.str(); partname.append(charnum); //put the part name together //Write new file part fstream filePart; filePart.open(partname.c_str(),ios::out | ios::binary); //Open new file with the name built above //Check if near the end of file if (bigFile.tellg() < (size - (size%partsize))) { filePart.write(reinterpret_cast<char *>(&bigFile),partsize); //Write the selected amount to the file filePart.close(); //close file bigFile.seekg(partsize, ios::cur); //move pointer to next position to be written } //Changes the size of the last volume because it is the end of the file else { filePart.write(reinterpret_cast<char *>(&bigFile),(size%partsize)); //Write the selected amount to the file filePart.close(); //close file } cout << "File " << CurrentPath << partname << " produced" << endl; //display the progress of the split } bigFile.close(); cout << "Split Complete." << endl; return 0; } Any ideas? Thanks!

  • Problems with Asynchronous UDP Sockets

    - by ihatenetworkcoding
    Hi, I'm struggling a bit with socket programming (something I'm not at all familiar with) and I can't find anything which helps from google or MSDN (awful). Apologies for the length of this. Basically I have an existing service which recieves and responds to requests over UDP. I can't change this at all. I also have a client within my webapp which dispatches and listens for responses to that service. The existing client I've been given is a singleton which creates a socket and an array of response slots, and then creates a background thread with an infinite looping method that makes "sock.Receive()" calls and pushes the data received into the slot array. All kinds of things about this seem wrong to me and the infinite thread breaks my unit testing so I'm trying to replace this service with one which makes it's it's send/receives asynchronously instead. Point 1: Is this the right approach? I want a non-blocking, scalable, thread-safe service. My first attempt is roughly like this, which sort of worked but the data I got back was always shorter than expected (i.e. the buffer did not have the number of bytes requested) and seemed to throw exceptions when processed. private Socket MyPreConfiguredSocket; public object Query() { //build a request this.MyPreConfiguredSocket.SendTo(MYREQUEST, packet.Length, SocketFlags.Multicast, this._target); IAsyncResult h = this._sock.BeginReceiveFrom(response, 0, BUFFER_SIZE, SocketFlags.None, ref this._target, new AsyncCallback(ARecieve), this._sock); if (!h.AsyncWaitHandle.WaitOne(TIMEOUT)) { throw new Exception("Timed out"); } //process response data (always shortened) } private void ARecieve (IAsyncResult result) { int bytesreceived = (result as Socket).EndReceiveFrom(result, ref this._target); } My second attempt was based on more google trawling and this recursive pattern I frequently saw, but this version always times out! It never gets to ARecieve. public object Query() { //build a request this.MyPreConfiguredSocket.SendTo(MYREQUEST, packet.Length, SocketFlags.Multicast, this._target); State s = new State(this.MyPreConfiguredSocket); this.MyPreConfiguredSocket.BeginReceiveFrom(s.Buffer, 0, BUFFER_SIZE, SocketFlags.None, ref this._target, new AsyncCallback(ARecieve), s); if (!s.Flag.WaitOne(10000)) { throw new Exception("Timed out"); } //always thrown //process response data } private void ARecieve (IAsyncResult result) { //never gets here! State s = (result as State); int bytesreceived = s.Sock.EndReceiveFrom(result, ref this._target); if (bytesreceived > 0) { s.Received += bytesreceived; this._sock.BeginReceiveFrom(s.Buffer, s.Received, BUFFER_SIZE, SocketFlags.None, ref this._target, new AsyncCallback(ARecieve), s); } else { s.Flag.Set(); } } private class State { public State(Socket sock) { this._sock = sock; this._buffer = new byte[BUFFER_SIZE]; this._buffer.Initialize(); } public Socket Sock; public byte[] Buffer; public ManualResetEvent Flag = new ManualResetEvent(false); public int Received = 0; } Point 2: So clearly I'm getting something quite wrong. Point 3: I'm not sure if I'm going about this right. How does the data coming from the remote service even get to the right listening thread? Do I need to create a socket per request? Out of my comfort zone here. Need help.

  • How do I make java wait for boolean to run funciton

    - by TWeeKeD
    I'm sure this is pretty simple but I can't figure out and it sucks I'm up on suck on (what should be) an easy step. ok. I have a method that runs one function that give a response. this method actually handles the uploading of the file so o it takes a second to give a response. I need this response in the following method. sendPicMsg needs to complete and then forward it's response to sendMessage. Please help. b1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(!uploadMsgPic.equalsIgnoreCase("")){ Log.v("response","Pic in storage"); sendPicMsg(); sendMessage(); }else{ sendMessage(); } 1st Method public void sendPicMsg(){ Log.v("response", "sendPicMsg Loaded"); if(!uploadMsgPic.equalsIgnoreCase("")){ final SharedPreferences preferences = this.getActivity().getSharedPreferences("MyPreferences", getActivity().MODE_PRIVATE); AsyncHttpClient client3 = new AsyncHttpClient(); RequestParams params3 = new RequestParams(); File file = new File(uploadMsgPic); try { File f = new File(uploadMsgPic.replace(".", "1.")); f.createNewFile(); //Convert bitmap to byte array Bitmap bitmap = decodeFile(file,400); ByteArrayOutputStream bos = new ByteArrayOutputStream(); bitmap.compress(CompressFormat.PNG, 0 /*ignored for PNG*/, bos); byte[] bitmapdata = bos.toByteArray(); //write the bytes in file FileOutputStream fos = new FileOutputStream(f); fos.write(bitmapdata); params3.put("file", f); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } params3.put("email", preferences.getString("loggedin_user", "")); params3.put("webversion", "1"); client3.post("http://peekatu.com/apiweb/msgPic_upload.php",params3, new AsyncHttpResponseHandler() { @Override public void onSuccess(String response) { Log.v("response", "Upload Complete"); refreshChat(); //responseString = response; Log.v("response","msgPic has been uploaded"+response); //parseChatMessages(response); response=picurl; uploadMsgPic = ""; if(picurl!=null){ Log.v("response","picurl is set"); } if(picurl==null){ Log.v("response", "picurl no ready"); }; } }); sendMessage(); } } 2nd Method public void sendMessage(){ final SharedPreferences preferences = this.getActivity().getSharedPreferences("MyPreferences", getActivity().MODE_PRIVATE); if(preferences.getString("Username", "").length()<=0){ editText1.setText(""); Toast.makeText(this.getActivity(), "Please Login to send messages.", 2); return; } AsyncHttpClient client = new AsyncHttpClient(); RequestParams params = new RequestParams(); if(type.equalsIgnoreCase("3")){ params.put("toid",user); params.put("action", "sendprivate"); }else{ params.put("room", preferences.getString("selected_room", "Adult Lobby")); params.put("action", "insert"); } Log.v("response", "Sending message "+editText1.getText().toString()); params.put("message",editText1.getText().toString() ); params.put("media", picurl); params.put("email", preferences.getString("loggedin_user", "")); params.put("webversion", "1"); client.post("http://peekatu.com/apiweb/messagetest.php",params, new AsyncHttpResponseHandler() { @Override public void onSuccess(String response) { refreshChat(); //responseString = response; Log.v("response", response); //parseChatMessages(response); if(picurl!=null) Log.v("response", picurl); } }); editText1.setText(""); lv.setSelection(adapter.getCount() - 1); }
