Installing Bugzilla on Ubuntu 9.04 and Plesk

- by makeflo

Hey guys. I'm trying to install the latest Bugzilla version on my ubuntu server. (Want to use a subdomain like bugs.domain.com) I already installed all necessary perl modules and check_modules.pl doesn't show any errors. But when I'm running the testserver.pl script I get the following: TEST-OK Webserver is running under group id in $webservergroup TEST-FAILED Fetch of images/padlock.png failed I'm also not able to visit ANY file within the bugzilla folder from the browser. I'm always getting a 404 error. The bugzilla folder and all containing files are set to apache as the owner. I tried to enter the apache configuration form the installation guide in the http.include file of the domain and in the vhosts.conf file of the subdomain as well. I don't know what to do... Playing with plesks' suexecgroup doesn't bring any solution... I hope you can help me! Thanks in advance!

Converting Json to Java

- by Binaryrespawn

Hi all, I want to be able to access properties from a json string within my java action method. The string is available by simply saying myJsonString = object.getJson(); Below is an example of what the string can look like: {'title': 'Computing and Information systems','id':1,'children': 'true','groups': [{'title': 'Level one CIS','id':2,'children': 'true','groups':[{'title': 'Intro To Computing and Internet','id':3,'children': 'false','groups':[]}]}]} In this string every json object contains an array of other json objects. The intention is to extract a list of id's where any given object possessing a group property that contains other json objects. I looked at google's Gson as a potential json plugin. Can anyone offer some form of guidance as to how I can generate java from this json string? Thank you, Kind regards.

Having trouble scraping an ASP .NET web page

- by Seth

I am trying to scrape an ASP.NET website but am having trouble getting the results from a post. I have the following python code and am using httplib2 and BeautifulSoup: conn = Http() # do a get first to retrieve important values page = conn.request(u"http://somepage.com/Search.aspx", "GET") #event_validation and viewstate variables retrieved from GET here... body = {"__EVENTARGUMENT" : "", "__EVENTTARGET" : "" , "__EVENTVALIDATION": event_validation, "__VIEWSTATE" : viewstate, "ctl00_ContentPlaceHolder1_GovernmentCheckBox" : "On", "ctl00_ContentPlaceHolder1_NonGovernmentCheckBox" : "On", "ctl00_ContentPlaceHolder1_SchoolKeyValue" : "", "ctl00_ContentPlaceHolder1_SchoolNameTextBox" : "", "ctl00_ContentPlaceHolder1_ScriptManager1" : "ctl00_ContentPlaceHolder1_UpdatePanel1|cct100_ContentPlaceHolder1_SearchImageButton", "ct100_ContentPlaceHolder1_SearchImageButton.x" : "375", "ct100_ContentPlaceHolder1_SearchImageButton.y" : "11", "ctl00_ContentPlaceHolder1_SuburbTownTextBox" : "Adelaide,SA,5000", "hiddenInputToUpdateATBuffer_CommonToolkitScripts" : 1} headers = {"Content-type": "application/x-www-form-urlencoded"} resp, content = conn.request(url,"POST", headers=headers, body=urlencode(body)) When I print content I still seem to be getting the same results as the "GET" or is there a fundamental concept I'm missing to retrieve the result values of an ASP .NET post?

Need PHP Email Script Solution

- by JCHASE11

Designing forms has always been fun, but getting them to send email on the server side is another story. I have used various email scripts (dynaform,phpmailer, etc), and have experienced a ton of problems. So here is the site I am working on: Contact On the Right. It is very basic: no validation, no required fields. I simply need anything that is entered to be sent back to me. Does anyone know of any BASIC PHP form processing scripts, or have a few lines of code that would work here? I'm not a PHP guy, so I am struggling! Thanks in advance.

forwarding a notification to another class

- by Mike

I am using this method - (void)keyboardWillShow:(NSNotification *)notification that is triggered when the keyboard shows. When this method is triggered, it receives a notification that contains several parameters about the keyboard, as the animation duration, animation curve and frame. I need to forward this notification and all its parameters to another class. So, I've tried to do this inside keyboardWillShow: [[NSNotificationCenter defaultCenter] postNotificationName:@"doSomething" object:notification userInfo:nil]; the doSomething notification runs doSomething method on another class, and it has this form: - (void) doSomething:(NSNotification *)notification { but when I try to read the notification values on this other class, using, for example, myRect = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue]; I obtain zero for all values. The notification is losing its parameters and not being forwarded. How can I do that? thanks.

Selecting a UserControl from XAML

- by kmontgom

I'm working on a problem right now where I need to embed a UserControl inside another UserControl. But, I need to determine at runtime which embedded UserControl to instantiate. This implies to me that some form of data binding and/or template selection mechanism has to be invoked, but I'm not sure how to proceed with the pure XAML approach. If I was to do this with code, I would define some sort of container control in the parent UserControl, and then in the code-behind, implement some logic which would instantiate the appropriate child UserControl and then insert it as Content into the specified container in the parent UserControl. Can this be done using only XAML, or is some sort of code-behind required?

My PHP login no longer works

- by Matt Clayton

This page worked like a charm for years... enter the correspondng user id and password and you would be redirected to your directory. Now suddenly, all attempts to log in - valid or otherwise - result in the page remaining static... no message, no redirect, nothing. Nothing in the code has changed, it just plain doesn't work anymore. Could this be the result of some kind of change on the server side? Yeah, I know it's not super secure, but it was good enough for our purposes. I'm certainly open to better suggestions. I just need it to work... and keep working. Please be gentle! I know almost nothing of programming. Here is the page code: <meta http-equiv="Content-Type" content="text/html;charset=utf-8" > <link href="ilium.css" rel="stylesheet" media="screen"> <title>Ilium: Client Login</title> </head> <body bgcolor="#bfbfcc" background="img/loginbg.gif"> <?php /* init vars */ $userExists = false; $userIndex = -1; $authenicated = false; /*********************************************** * edit this to add new users/password * * - add user/pass/directory to the array * * below: must be in same array index to work * ***********************************************/ $user = array('foo', 'bar'); $pass = array('foo', 'bar'); $directory = array('foo', 'bar'); // run user/pass check if data passed if (isset($username) && isset($password)) { // check if user name exists for ($i = 0; $i < count($user); $i++) { if ($user[$i] == $username) { $userExists = true; $userIndex = $i; break; } } // so user exists, now test password if ($userExists) { $message = $message .

Textbox1.Focus(); does not work; as does not Page.SetFocus(Textbox1); why?

- by b0x0rz

as stated both of these do not work: Textbox1.Focus(); or Page.SetFocus(Textbox1); any idea why? this is the control itself: <asp:TextBox ID="Textbox1" ClientIDMode="Static" CssClass="Textbox1" runat="server" MaxLength="80"></asp:TextBox> it is located on a page, two master pages deep. the form tag is on the second master page, so that is why the focus is not being set there. not working in: ie, firefox, chrome and safari (all latest versions). help! thnx

Precompile Lambda Expression Tree conversions as constants?

- by Nathan

It is fairly common to take an Expression tree, and convert it to some other form, such as a string representation (for example this question and this question, and I suspect Linq2Sql does something similar). In many cases, perhaps even most cases, the Expression tree conversion will always be the same, i.e. if I have a function public string GenerateSomeSql(Expression<Func<TResult, TProperty>> expression) then any call with the same argument will always return the same result for example: GenerateSomeSql(x => x.Age) //suppose this will always return "select Age from Person" GenerateSomeSql(x => x.Ssn) //suppose this will always return "select Ssn from Person" So, in essence, the function call with a particular argument is really just a constant, except time is wasted at runtime re-computing it continuously. Assuming, for the sake of argument, that the conversion was sufficiently complex to cause a noticeable performance hit, is there any way to pre-compile the function call into an actual constant?

How to get login password in servlets

- by Dusk

I've successfully implemented form based authentication, and now I want to get the username and password to initialize session object in javamail from servlets. How can I do that? I can getlogin username by using method request.getRemoteUser(), but I don't know how to get the password. If I create any session object like: authentication = new PasswordAuthentication(user,password); Properties props = new Properties(); props.put("mail.host", "localhost"); props.put("mail.debug",true); props.put("mail.store.protocol", "pop3"); props.put("mail.transport.protocol", "smtp"); Session session = Session.getInstance(props, this); then how can I get inbox messages from mail server based upon particular username and password, if I don't pass any password from servlets to PasswordAuthentication object?

Scaffolding Web Services in Grails

- by Dan

I need to implement a web app, but instead of using relational database I need to use different SOAP Web Services as a back-end. An important part of application only calls web services and displays the result. Since Web Services are clearly defined in form of Operation: In parameters and Return Type it seems to me that basic GUI could be easily constructed just like in the case of scaffolding based on Domain Entities. For example in case of SearchProducts web service operation I need to enter search parameters as input, so the search page can be constructed. Operation will return a list of products, so I need a page that will display this list in some kind of table. Is there already some library in grails that let you achieve this. If not, how would you go about creating one?

DBLinq not generating where clause

- by sipwiz

I'm testing out DBLinq-0.18 and DBLinq from SVN Trunk with MySQL and Postgresql. I'm only using a very simple query but on both database DBLinq is not generating a Where clause. I have confirmed this by turning on statement logging on Postgresql to check exactly what request DBLinq is sending. My Linq query is: MyDB db = new MyDB(new NpgsqlConnection("Database=database;Host=localhost;User Id=postgres;Password=password")); var customers = from customer in db.Customers where customer.CustomerUserName == "test" select customer; The query works ok but the SQL generated by DBLinq is of the form: select customerusername, customerpassword .... from public.customers There is no Where clause which means DBLinq must be pulling the whole table down before running the Linq query. Has anyone had any experience with DBLinq and know what I could be doing wrong?

Author in wiki, generate PDF documents, CHM files or embedded help

- by Dilum Ranatunga

Anyone know of a wiki or wiki plugin that generates a PDF file or CHM file that spans the entire wiki? I would like to have control of the table of contents. I would like the internal and external links to work. Ideally allow for tweaking the output template, but that is not a deal-breaker. I want to generate content using WIKI syntax and mindset (lots of cross-links etc), but ship the content in PDF, CHM or an embedded application form. Something friendlier than installing the wiki software on the enduser machine...

Essential skills of a Data Scientist

- by harshsinghal

I would like to know more about the relevant skills in the arsenal of a Data Scientist, and with new technologies coming in every day, how one picks and chooses the essentials. A few ideas germane to this discussion: Knowing SQL and the use of a DB such as MySQL, PostgreSQL was great till the advent of NoSql and non-relational databases. MongoDB, CouchDB etc. are becoming popular to work with web-scale data. Knowing a stats tool like R is enough for analysis, but to create applications one may need to add Java, Python, and such others to the list. Data now comes in the form of text, urls, multi-media to name a few, and there are different paradigms associated with their manipulation. What about cluster computing, parallel computing, the cloud, Amazon EC2, Hadoop ? OLS Regression now has Artificial Neural Networks, Random Forests and other relatively exotic machine learning/data mining algos. for company Thoughts?

How to limit choice field options based on another choice field in django admin

- by umnik700

I have the following models: class Category(models.Model): name = models.CharField(max_length=40) class Item(models.Model): name = models.CharField(max_length=40) category = models.ForeignKey(Category) class Demo(models.Model): name = models.CharField(max_length=40) category = models.ForeignKey(Category) item = models.ForeignKey(Item) In the admin interface when creating a new Demo, after user picks category from the dropdown, I would like to limit the number of choices in the "items" drop-down. If user selects another category then the item choices should update accordingly. I would like to limit item choices right on the client, before it even hits the form validation on the server. This is for usability, because the list of items could be 1000+ being able to narrow it down by category would help to make it more manageable. Is there a "django-way" of doing it or is custom JavaScript the only option here?

C# MDX RenderToSurface, where to reset after device is lost?

- by Moritz Schöfl

Hi, I got a problem with the RenderToSurface class. When I resize the Form of my Device, the Draw method is still called, but doesnt throw an Exception, it looks like this: device.Clear(ClearFlags.Target, Color.Red, 0, 0); device.BeginScene(); // here is out commented code device.EndScene(); device.Present(); In another method, I wrote this: renderToSurface.BeginScene(surfaces[currentIndex]); // here is out commented code renderToSurface.EndScene(Filter.None); and this method seems to throw a nullpointer exception when I resize the window; So my question is: - where to reset / restore / handle the renderToSurface class? (i tried it with the DeviceReset event like following - void OnDeviceReset(object sender, EventArgs e) { renderToSurface = new RenderToSurface(Game.Device, Game.ClientSize.Width, Game.ClientSize.Height, Format.A8R8G8B8, true, DepthFormat.D16); } )

Rails: Polymorphic User Table a good idea with AuthLogic?

- by sscirrus

Hi everyone, I have a system where I need to login three user types: customers, companies, and vendors from one login form on the home page. I have created one User table that works according to AuthLogic's example app at http://github.com/binarylogic/authlogic_example. I have added a field called "User Type" that currently contains either 'Customer', 'Company', or 'Vendor'. Note: each user type contains many disparate fields so I'm not sure if Single Table Inheritance is the best way to go (would welcome corrections if this conclusion is invalid). Is this a polymorphic association where each of the three types is 'tagged' with a User record? How should my models look so I have the right relationships between my User table and my user types Customer, Company, Vendor? Thanks very much!

Django: How to create a model dynamically just for testing

- by muhuk

I have a Django app that requires a settings attribute in the form of: RELATED_MODELS = ('appname1.modelname1.attribute1', 'appname1.modelname2.attribute2', 'appname2.modelname3.attribute3', ...) Then hooks their post_save signal to update some other fixed model depending on the attributeN defined. I would like to test this behaviour and tests should work even if this app is the only one in the project (except for its own dependencies, no other wrapper app need to be installed). How can I create and attach/register/activate mock models just for the test database? (or is it possible at all?) Solutions that allow me to use test fixtures would be great.

JSF2 - Why does render response not rerender component setting?

- by fekete-kamosh

From the tutorial: "If the request is a postback and errors were encountered during the apply request values phase, process validations phase, or update model values phase, the original page is rendered during Render response phase" (http://java.sun.com/javaee/5/docs/tutorial/doc/bnaqq.html) Does it mean that if view is restored in "Restore View" phase and then any apply request/validation/update model phase fails and skips to "Render response" that Render response only passes restored view without any changes to client?

Problem referencing querystring using fb:req-choice

Hi all, I am building a small facebook application. I am using asp.net and currently working with the fb:req-choice control (tied along with fb:request-form and fb:multi-friend-selector). Problem is, that when I specify the redirect url for when the user clicks my invitation, instead of getting what I specified: http://apps.facebook.com/myApp/forum.aspx?tId=1&ref=app&code=2.74rRNejG7tpAOqgDCNf8qA__.3600.1275202400-106570384737670%7CPi8JpoHDW3xGuq2lxdZl1d4CLUU.

Rails show latest entry

- by Danny McClelland

Hi Everyone, I have a working Rails application on version 2.3.5 - I am using many to many model relations and have got almost everything working. What I would like to do is on my new kase page show the most recent kase job ref at the top. So for example, if I created a new kase with a job ref of "001", if I then went to create a new kase it would show at the top "Your previous kases reference was 001". I have the field of jobref in the new kase form, so I am trying to workout what I need to do to output only the last jobref. If that makes sense! Thanks, Danny
