  • Rest WebService error handling.

    - by Pratik
    Hi there, I am using RestWebservice for few basic operations , like creating/searching. The request xml looks something like this <customer> <name/> ..... </customer> For a successful operation I return the same customer XML with extra fields populated in it(eg. systemId etc which we blank in the request) . with Response.Status=2000 For an unsuccessful operation i return something like this with different error codes . e.g Response.Status = 422(Unprocessable entity) Response.Status= 500(Internal Server Error) and few others.. <errors> <error> An exception occurred while creating the customer</error> <error> blah argument is not valid.</error> </errors> Now i am not sure , whether this is the correct way of sending the errors to the client. Maybe it should be present in the header of the response. I will really appreciate any help. Thanks!

  • Which technology is best suited to store and query a huge readonly graph?

    - by asmaier
    I have a huge directed graph: It consists of 1.6 million nodes and 30 million edges. I want the users to be able to find all the shortest connections (including incoming and outgoing edges) between two nodes of the graph (via a web interface). At the moment I have stored the graph in a PostgreSQL database. But that solution is not very efficient and elegant, I basically need to store all the edges of the graph twice (see my question PostgreSQL: How to optimize my database for storing and querying a huge graph). It was suggested to me to use a GraphDB like neo4j or AllegroGraph. However the free version of AllegroGraph is limited to 50 million nodes and also has a very high-level API (RDF), which seems too powerful and complex for my problem. Neo4j on the other hand has only a very low level API (and the python interface is not mature yet). Both of them seem to be more suited for problems, where nodes and edges are frequently added or removed to a graph. For a simple search on a graph, these GraphDBs seem to be too complex. One idea I had would be to "misuse" a search engine like Lucene for the job, since I'm basically only searching connections in a graph. Another idea would be, to have a server process, storing the whole graph (500MB to 1GB) in memory. The clients could then query the server process and could transverse the graph very quickly, since the graph is stored in memory. Is there an easy possibility to write such a server (preferably in Python) using some existing framework? Which technology would you use to store and query such a huge readonly graph?

  • How do you find a functions virtual call address in assembly?

    - by Daniel
    I've googled around but i'm not sure i am asking the right question or not and i couldn't find much regardless, perhaps a link would be helpful. I made a c++ program that shows a message box, then I opened it up with Ollydbg and went to the part where it calls MessageBoxW. The call address of MessageBoxW changes each time i run the app as windows is updating my Imports table to have the correct address of MessageBoxW. So my question is how do i find the virtual addres of MessageBoxW to my imports table and also how can i use this in ollydbg? Basically I'm trying to make a code cave in assembly to call MessageBoxW again. I got fairly close once by searching the executable with a hex editor and found the position of the call, and I think I found the virtual address. But when i call that virtual address in olly and saved it to the executable, the next time i opened it the call was replaced with a bunch of DB xyz (which looked like the virtual address but why did the call get removed? Sorry if my terminology is off as i'm new to this so i'm not quite sure what to call things.

  • SEO on a Database Driven Website

    - by Ryan Giglio
    I have a question about a site I'm developing. It is a database driven directory site where people can make a profile and list themselves in one or many area codes and in one or many fields of work. When someone is looking for a person to hire, they enter one or more area codes to look in (or select them with checkboxes) and when the form submits, it saves these as a cookie so the site remembers what location you were searching in. You then narrow down your search by category and field (which are links) and get a listing of all the profiles that match your search. What I am concerned about is this: because a search engine can't type in or select area codes to search in, how is it going to find and index any of the profile pages? It doesn't allow the user to search for people without first selecting an area code, because there's no practical purpose to do so. There would also be no practical purpose from a user experience/usability standpoint of simply having a list of each area code as a link to the categories page, but as far as I know, isn't that the only way for search engines to see every person? How does a site like Facebook accomplish this? There isn't some sort of master directory with a link to ever single Facebook user's profile page, and yet they're often the #1 search result for a person's name.

  • SOLR phrase query

    - by Alex
    I have a slight problem when searching with SOLR 4.0 and attempting a phrase query. I have a field called "idx_text_general_ci" which is a case insensitive (all lowercased) field made up of all fields. When I try and search for a phrase (marine fitter) my SOLR refuses to search for the phrase instead splitting the phrase into 2 words - /select?defType=edismax&q=idx_text_general_ci:marine%20fitter&debugQuery=true debugQuery=true output below: <lst name="debug"> <str name="rawquerystring">idx_text_general_ci:marine fitter</str> <str name="querystring">idx_text_general_ci:marine fitter</str> <str name="parsedquery"> (+(idx_text_general_ci:marine DisjunctionMaxQuery((id:fitter))))/no_coord </str> <str name="parsedquery_toString">+(idx_text_general_ci:marine (id:fitter))</str> As you can see above it splits the query into 2 parts (idx_text_general_ci:marine then id:fitter). THe problem I have is that I have an exact match for "marine fitter" that appears twice in the idx_text_general_ci field yet it's ranked with a lesser score than a document with the word "marine" appearing 3 times. I know this will not be the case if my SOLR was to search the field with the phrase as expected. If I wrap the phrase in quotes I get zero results. Any help or a nudge in the right direction would be much appreciated. Thanks in advance Alex

  • Can I copy/clone a function in JavaScript?

    - by Craig Stuntz
    I'm using jQuery with the validators plugin. I would like to replace the "required" validator with one of my own. This is easy: jQuery.validator.addMethod("required", function(value, element, param) { return myRequired(value, element, param); }, jQuery.validator.messages.required); So far, so good. This works just fine. But what I really want to do is call my function in some cases, and the default validator for the rest. Unfortunately, this turns out to be recursive: jQuery.validator.addMethod("required", function(value, element, param) { // handle comboboxes with empty guids if (someTest(element)) { return myRequired(value, element, param); } return jQuery.validator.methods.required(value, element, param); }, jQuery.validator.messages.required); I looked at the source code for the validators, and the default implementation of "required" is defined as an anonymous method at jQuery.validator.messages.required. So there is no other (non-anonymous) reference to the function that I can use. Storing a reference to the function externally before calling addMethod and calling the default validator via that reference makes no difference. What I really need to do is to be able to copy the default required validator function by value instead of by reference. But after quite a bit of searching, I can't figure out how to do that. Is it possible? If it's impossible, then I can copy the source for the original function. But that creates a maintenance problem, and I would rather not do that unless there is no "better way."

  • Open source file upload with no timeout on IIS6 with ASP, ASP.NET 2.0 or PHP5

    - by Christopher Done
    I'm after a cross-platform cross-browser way of uploading files such that there is no timeout. Uploads aren't necessarily huge -- some just take a long time to upload because of the uploader's slow connection -- but the server times out anyway. I hear that there are methods to upload files in chunks so that somehow the server decides not to timeout the upload. After searching around all I can see is proprietary upload helpers and Java and Flash (SWFUpload) widgets that aren't cross-platform, don't upload in chunks, or aren't free. I'd like a way to do it in any of these platforms (ASP, ASP.NET 2.0 or PHP5), though I am not very clued up on all this .NET class/controller/project/module/visual studio/compile/etc stuff, so some kind of runnable complete project that runs on .NET 2.0 would be helpful. PHP and ASP I can assume will be more straight-forward. Unless I am completely missing something, which I suspect/hope I am, reasonable web uploads are bloody hard work in any language or platform. So my question is: how can I perform web browser uploads, cross-platform, so that they don't timeout, using free software? Is it possible at all?

  • Open Source CMS (.Net vs Java)

    - by CmsAndDotNetKindaGuy
    I must say up-front that this is not a strictly programming-related question and a very opinionated one. I am the lead developer of the dominant .Net CMS in my country and I don't like my own product :). Managerial decisions over what is important or not and large chunks of legacy code done before I joined gives me headache every day I go for work. Anyway, having a vast amount of experience in web industry and a very good grasp of C# and programming practices I'm designing my own CMS the past few months. Now the problem is that I'm an open source kinda guy so I have a dilemma. Should I use C# and .Net which has crippled multi-platform support or should I drop .Net entirely and start learning Java where I can create a truly open-source and cross-platform CMS? Please don't answer that I should contribute to an existing open source CMS. I ruled that out after spending a great deal of time searching for something similar in structure to what I have in mind. I am not a native speaker, so feel free to correct my syntax or rephrase my question.

  • Correct method to search for AD user by email address from .NET

    - by BrianLy
    I'm having some issues with code that is intended to find a user in Active Directory by searching on their email address. I have tried 2 methods but I'm sometimes finding that the FindOne() method will not return any results on some occasions. If I look up the user in the GAL in Outlook I see the SMTP email address listed. My end goal is to confirm that the user exists in AD. I only have the email address as search criteria, so no way to use first or last name. Method 1: Using mail property: DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(mail=" + email + ")"; search.PropertiesToLoad.Add("mail"); SearchResult result = search.FindOne(); Method 2: proxyAddresses property: DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(proxyAddresses=SMTP:" + email + ")"; // I've also tried with =smtp: search.PropertiesToLoad.Add("mail"); SearchResult result = search.FindOne(); I've tried changing the case of the email address input but it still does not return a result. Is there a problem here with case sensitivity? If so, what is the best way to resolve it?

  • Android change context for findViewById to super from inline class

    - by wuntee
    I am trying to get the value of a EditText in a dialog box. A the "*"'ed line in the following code, the safeNameEditText is null; i am assuming because the 'findVeiwById' is searching on the context of the 'AlertDialog.OnClickListener'; How can I get/change the context of that 'findViewById' call? protected Dialog onCreateDialog(int id) { AlertDialog.Builder builder = new AlertDialog.Builder(this); switch(id){ case DIALOG_NEW_SAFE: builder.setTitle(R.string.news_safe); builder.setIcon(android.R.drawable.ic_menu_add); LayoutInflater factory = LayoutInflater.from(this); View newSafeView = factory.inflate(R.layout.newsafe, null); builder.setView(newSafeView); builder.setPositiveButton(R.string.ok, new AlertDialog.OnClickListener(){ public void onClick(DialogInterface dialog, int which) { * EditText safeNameEditText = (EditText) findViewById(R.id.new_safe_name); String safeName = safeNameEditText.getText().toString(); Log.i(LOG, safeName); setSafeDao(safeName); } }); builder.setNegativeButton(R.string.cancel, new AlertDialog.OnClickListener(){ public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }); return(builder.create()); default: return(null); } }

  • CSS Parser - Insert mtimes

    - by brad
    What command line tool can I use to automatically insert mtimes into urls in my css files for the purposes of breaking the cache? /* before */ .example { background: url(example.jpg); } /* after */ .example { background: url(example.jpg?1271298451); } Also, I would like this tool to spit out the latest mtime as the css files mtime. (If the css file is still cached then the new urls will not get to the client.) In searching the web, I have found very few tools that can do this. I am even considering rolling my own, but have found very little in the way of css parsers that are actively maintained. A candidate should be: fast (I don't want to wait 30 seconds on deployment) command line accessible (something like "cat foo.css bar.css | cssmtime out.css") What I've found so Far yui compressor - initially I thought I would extend the yui compressor to do this, but found that it is implemented as a bunch of regex's and not a parser. csstidy - last release was in 2007 and development has been suspended, but does have an option for inserting mtimes (also written in php, something I have no experience in) cssutils - python sac implementation - seems to be actively maintained, but also seems like overkill for my needs. Also, written in python which I have experience with csspool - ruby sac implementation - I don't know much ruby, but would like to learn other sac implementations - There are several java implementations, and a c implementation neither of which I know much about What's your experience? Have you used any of these libraries? Was the experience positive? Would you recommend I go with them for my purposes?

  • Application passwords and SQLite security

    - by Bryan
    I have been searching on google for information regarding application passwords and SQLite security for some time, and nothing that I have found has really answered my questions. Here is what I am trying to figure out: 1) My application is going to have an optional password activity that will be called when the application is first opened. My questions for this are a) If I store the password via android preference or SQLite database, how can I ensure security and privacy for the password, and b) how should password recovery be handled? Regarding b) from above, I have thought about requiring an email address when the password feature is enabled, and also a password hint question for use when requesting password recovery. Upon successfully answering the hint question, the password is then emailed to the email address that was submitted. I am not completely confident in the security and privacy of the email method, especially if the email is sent when the user is connected to an open, public wireless network. 2) My application will be using an SQLite database, which will be stored on the SD card if the user has one. Regardless of whether it is stored on the phone or the SD card, what options do I have for data encryption, and how does that affect the application performance? Thanks in advance for time taken to answer these questions. I think that there may be other developers struggling with the same concerns.

  • Multiple dynamic timers

    - by Rickard
    I am working on a project where I need to let the user create one (or more) timers to fire off an event. The user is supposed to define variables such as if the timer should be active and how often the timer will fire along with some other variables of what will happen when the timer is fiering. All these variables are stored in a dictionary (Disctionary) where the object holds all the variables the user has set and the string is the name that the user has chosen for this timer. I then want my program to loop through this dictionary and search for all objects which has the variable t_Active set to true (this I have already achieved). What I need help with figuring out is the follwoing: When it detects the variable, and if it's set to true, I need the program to see if there is already a timer created for this. If it isn't, it should create one and set the relevant parameters for the timer. The two variables t_num and t_period should decide the interval of the timer. t_num is an int and t_period is a string which will be set to either minutes, hours or days. Combining t_num with 60000 (minutes), 3600000 (hours) or 86400000 should give the corrct interval. But how would I go on about programatically create a timer for each user-defined active object? And how do I get the program to detect wether or not a timer has already been created? I have been searching both here and on google, but so far I haven't come across something that makes sense to me. I am still learning C#, so what make sense to you guys may not neccessarilly make sense to me yet. :) I hope I have explaned what I need good enough, please do ask me to clarify if you don't get me. Edit: Maybe I should also mention that the mentioned dictionary will also be saved to an XML file to that the user can pick up all the settings they made at any time.

  • Set Server Side OnClick() event Programmatically

    - by Corey O.
    I am looking for a way to programmatically set the OnClick event handler for a TableCell object. The ASP equivalent of what I'm trying to do will look like this: <asp:TableCell OnClick="clickHandler" runat="server">Click Me!</asp:TableCell> In the above example, "clickHandler" is a server-side function defined in the .cs CodeBehind. public virtual void clickHandler(object sender, EventArgs args) {...} However, for my situation, this TableCell object needs to be created dynamically, so setting it in an ASP tag is not an option. I am trying to do something like the following in the CodeBehind: System.Web.UI.WebControls.TableRow row = new System.Web.UI.WebControls.TableRow(); System.Web.UI.WebControls.TableCell cell = new System.Web.UI.WebControls.TableCell(); cell.Text = "Click Me!"; cell.Attributes.Add("onClick", "clickHandler"); row.Cells.Add(cell); Unfortunately, in this situation: cell.Attributes.Add("onClick", "clickHandler"); the "clickHandler" only works as a client-side javascript function. What I'm looking for is a way to link the server-side clickHandler() function, defined in the .cs CodeBehind, to this table cell. After an afternoon of searching, I have been unable to come up with a working solution. Thanks in advance for any help.

  • PyQt4: Hide widget and resize window

    - by masterLoki
    Hi everyone: I'm working with several widgets but the solution just won't come out. What I have is a series of buttons in series of QHBoxLayouts. Some buttons are hidden by default, but they will appear when needed. To solve space issues, all buttons have a minimum and maximum size so they always look well packed. Also I have a QTextEdit, visible by default, which is in a QVBoxLayout with the QHBoxLayout that hold the buttons So the problem is this: When I hide the QTextEdit and show the other buttons, the window won't resize. After searching I found that using self.ui.layout().setSizeConstraint(QtGui.QLayout.SetFixedSize) will do the trick, but the problem is that it takes the maximum size from all widgets, therefore I end a huge window. Doing self.ui.layout().setSizeConstraint(QtGui.QLayout.SetMinAndMaxSize) won't resize the window I already tried using self.ui.resize(0,0), and when doing a self.ui.layout().update() I got False (which I find odd, http://doc.trolltech.com/4.6/qlayout.html#activate), and also tried to override sizeHint() but it keeps using the max size for all widgets. Is there a way to resize the window and while taking care of the min and max size of a widget? Thanks in advance

  • How to bind a table in a dataset to a WPF datagrid in C# and XAML

    - by Jim Thomas
    I have been searching to hours for something very simple: bind a WPF datagrid to a datatable in order to see the columns at design-time. I can’t get any of the examples to work for me. Here is the C# code to populate the datatable InfoWork inside the dataset info: info = new Info(); InfoTableAdapters.InfoWorkTableAdapter adapter = new InfoTableAdapters.InfoWorkTableAdapter(); adapter.Fill(info.InfoWork); The problem is no matter how I declare ‘info’ or ‘infoWork’ Visual Studio/XAML can’t find it. I have tried: <Window.Resources> <ObjectDataProvider x:Key="infoWork" ObjectType="{x:Type local:info}" /> </Window.Resources> I have also tried this example from wpf.codeplex, but XAML doesn’t even like the “local:” keyword! <Window.Resources> <local:info x:Key="infoWork"/> </Window.Resources> There are really two main questions here: 1) How do I declare the table InfoWork in C# so that XAML can see it? I tried declaring it Public in the window class that XAML exists in with no success. 2) How do I declare the windows resource in XAML, specifcally the datatable inside the dataset? Out of curiosity, is there a reason that ItemsSource just doesn't show up as a property that be set in the properties design window?

  • Explaining verity index and document search limits

    - by Ahmad
    As present, we currently have a CF8 standard edition server which have some limitations around verity indexing. According to Adobe Verity Server has the following document search limits (limits are for all collections registered to Verity Server): - 10,000 documents for ColdFusion Developer Edition - 125,000 documents for ColdFusion Standard Edition - 250,000 documents for ColdFusion Enterprise Edition We have now reached a stage where the server wide number of documents indexed exceed 125k. However, the largest verity collection consists of about 25k documents(and this is expected to grow). Only one collection is ever searched at a time. In my understanding, this means that I can still search an entire collection with no restrictions. Is this correct? Or does it mean that only documents that were indexed across all collection prior to reaching the limit are actually searchable? We are considering moving to CF9 standard as a solution to this and to use the Solr solution which has no restrictions. The coldfusionjedi highlights some differences between Verity and Solr. However, before we upgrade I am trying to gain a clearer understanding of this before we commit to an upgrade. Can someone provide me a clear explanation as to what this means and how it actually affects verity searching and indexing?

  • Parsing/Tokenizing a String Containing a SQL Command

    - by Alan Storm
    Are there any open source libraries (any language, python/PHP preferred) that will tokenize/parse an ANSI SQL string into its various components? That is, if I had the following string SELECT a.foo, b.baz, a.bar FROM TABLE_A a LEFT JOIN TABLE_B b ON a.id = b.id WHERE baz = 'snafu'; I'd get back a data structure/object something like //fake PHPish $results['select-columns'] = Array[a.foo,b.baz,a.bar]; $results['tables'] = Array[TABLE_A,TABLE_B]; $results['table-aliases'] = Array[a=TABLE_A, b=TABLE_B]; //etc... Restated, I'm looking for the code in a database package that teases the SQL command apart so that the engine knows what to do with it. Searching the internet turns up a lot of results on how to parse a string WITH SQL. That's not what I want. I realize I could glop through an open source database's code to find what I want, but I was hoping for something a little more ready made, (although if you know where in the MySQL, PostgreSQL, SQLite source to look, feel free to pass it along) Thanks!

  • Matlab and .net problem with character string function input

    - by Peter
    I have a MATLAB function that I've compiled into a .net library. The function is a simple one that takes a character array as an input and a numeric array as output: function insert = money(dateLimit) .. insert = [1 2]; The function works fine when no function arguments are specified (a default argument is provided inside the function) Dim sf As New SpreadFinder.SpreadFinder Dim output = sf.money() As soon as an argument is specified .net complains. I'm thinking this should be easy and has been done before but searching through MATLAB documentation doesn't offer much help. Here's what I've tried. The sf.money() overload for the function with arguments is (numArgsOut as Integer, argsOut as MWArray, argsIn as MWArray) and hence that's what I've tried. What am I missing? Dim sf As New SpreadFinder.SpreadFinder Dim inputArgs(1) As Arrays.MWCharArray Dim dateLimitString As String = "some string" inputArgs(0) = New Arrays.MWCharArray(dateLimitString) Dim outputArgs(1) As Arrays.MWNumericArray outputArgs(0) = New Arrays.MWNumericArray() sf.money(1, outputArgs, inputArgs) Gives System.NullReferenceException : Object reference not set to an instance of an object. at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, Int32 numArgsIn, MWArray[] argsIn) at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, MWArray[]& argsOut, MWArray[] argsIn) at SpreadFinder.SpreadFinder.money(Int32 numArgsOut, MWArray[]& argsOut, MWArray[] argsIn)

  • PHP Variable with Array

    - by Crays
    Hi guys, i'm trying to make a "update user's power" page. It is something similar to those you can find in say, invisionfree forums. I need it to generate a list of members with checkbox [done] Add an option for it [done] What i don't know how to do is to update, to say, give all the selected users the selected power. Then i went searching for something and found most of them uses array to do this, but i never found one that actually explains how it works. The example i took (with my own modification) was this: while($row = mysql_fetch_array($result)) { echo '<tr>'.$id[]=$rows['id'].''; echo '<td width="50px" align="center" class="TableFormCell"><input type="checkbox" name="option[]" /></td>'; echo '<td width="170px" align="center" class="TableFormCell">'.$row['uname'].'</td>'; echo '</tr>'; } I'm not sure what exactly $id[]=$rows['id'] does I know after the row, my option[] would become an array of option[1], option[2], option[3] for what power should be given, i've got no problem with that but on how to update the database i'm got no clue... for($i=0;$i<$count;$i++){ $sql1="UPDATE ninos SET power='$power' WHERE id='$option[$i]'"; $result1=mysql_query($sql1); } So Say i have 5 users, Aye, Bee, Cee, Dee, Eee with IDs of 1,2,3,4,5 how can i make it so that my script would run like $sql1="UPDATE ninos SET power = '$power' Where id='1','2','3','4','5'"; Please help, thanks.

  • What is the correct way to implement a massive hierarchical, geographical search for news?

    - by Philip Brocoum
    The company I work for is in the business of sending press releases. We want to make it possible for interested parties to search for press releases based on a number of criteria, the most important being location. For example, someone might search for all news sent to New York City, Massachusetts, or ZIP code 89134, sent from a governmental institution, under the topic of "traffic". Or whatever. The problem is, we've sent, literally, hundreds of thousands of press releases. Searching is slow and complex. For example, a press release sent to Queens, NY should show up in the search I mentioned above even though it wasn't specifically sent to New York City, because Queens is a subset of New York City. We may also want to implement "and" and "or" and negation and text search to the query to create complex searches. These searches also have to be fast enough to function as dynamic RSS feeds. I really don't know anything about search theory, or how it's properly done. The way we are getting by right now is using a data mart to store the locations the releases were sent to in a single table. However, because of the subset thing mentioned above, the data mart is gigantic with millions of rows. And we haven't even implemented cities yet, and there are about 50,000 cities in the United States, which will exponentially increase the size of the data mart by so much I'm afraid it just won't work anymore. Anyway, I realize this is not a simple question and there won't be a "do this" answer. However, I'm hoping one of you can point me in the right direction where I can learn about how massive searches are done? Because I really know nothing about it. And such a search engine is turning out to be incredibly difficult to make. Thanks! I know there must be a way because if Google can search the entire internet we must be able to search our own database :-)

  • CLR Stored Procedures

    - by Paul Hatcherian
    In an ASP.NET application, I have a small number of fairly complex, frequently used operations to execute against a database. In these operations, one or more of several tables needs updates or inserts based a logical evaluation of both input parameters and values of certain tables. I've maintained a separation of logic and data access, so the operation currently looks like this: Request received from client Business layer invokes data layer to retrieve data from database Business layer processes result and determines which operation to execute Business layer invokes appropriate data operation Response sent to client As you can see, the client is kept waiting while two separate requests are made to the database. In searching for a solution to this, I've found CLR Stored Procedures, but I'm not sure if I have the right idea about what they are useful for. I have written a replacement for the code above which especially places steps 2-4 in a CLR SP. My understanding is that the SP will be executed locally by SQL Server and result in only one call being made to the server. My initial benchmark tests show this is actually orders of magnitude slower than my original code, but I attribute that recompilation of the code I have not worked out yet and/or some flaw in my environment. My question is basically, is this the intended use of CLR SPs or am I missing something? I realize this is a bit of a compromise structurally, so if there's a better way to do it I'd love to hear it.

  • How do I insert an input's value into a separate form?

    - by ryan
    I'm making a tool for my university that allows students to create a list of classes by doing the following: Searching by course title for their course via an autocomplete input field. Adding that course to a separate form that upon being submitted creates a course list. I am trying to link the autocomplete and the course list form with an 'add to course list' button that inserts a hidden input field into the course list form which can subsequently be submitted by a 'create course list' button. My question is this: How do I take the value of the autocomplete input and insert it into the course list form without using AJAX? So far I have something like the following: <%= text_field_with_auto_complete :course, :title, :size => 40 %> <%= link_to_function "Add to Course List" do |page| page.insert_html :top, :course_list, hidden_field(:courses, :course, {:value => "$('course_title').value"}) %> <% form_for(@course_list) do |f|%> <div id="course_list">Insert selected courses here.</div> <% end %>
