  • Rails 3 nested forms with has_many :through, entry in join table dosen't get deleted after update

    - by Hadi S.
    Hi, i have a 'User' model which has a has_many relationship to a 'Number' model through a join table 'user_number' model. I use accepts_nested_attributes_for :numbers, :allow_destroy = true in the 'User' model. Everything works fine except that whenever i delete a number from a user in the edit form, the associated number is deleted correctly in the 'number' table, but not the entry in the 'user_number' join table. In the update controller action i only use this: ... if @user.update_attributes(params[:user]) ... How can i force rails to also delete the associated entry in the join table?

  • Application Buddy Lists and Authentication - How does it all go together

    - by Krevin
    This is a broad but specific question. The idea is that we want to tie in a 'buddy' functionality to a communications app. Very broadly, I believe that the application clients would connect to a central database/auth service which would provide the buddy data and then allow client apps to connect directly to eachother, without passing communications through the server. Specifically, however, what solutions, software, products, servers, technologies, etc would be best to implement to handle such a task? Thanks for reading and responses are much appreciated. //edit: the com app may run on a linux distro, may be web based, or both

  • Best Version control for lone developer

    - by Stephen
    I'm a lone developer at the moment; please share you experiences on what is a good VC setup for a lone developer. My constraints are; I work on multiple machines and need to keep them synced up Sometimes I work offline I'm currently using Subversion(just the client to a remote server), and that is working ok. I'm interested in mecurial and git DVCS, but none of their use-cases make sense to my situation. EDIT: I've migrated my active development to Fossil http://www.fossil-scm.org/ after trialing it with a client. I really like the features to autosync my repositories(reducing accidental forks), the documentation support(both wiki and embedded/versioned) that supports my need to document the code and the project in different spaces, the easy to configure issue tracker, nice access control, skinnable web interface and helpful community.

  • How to get the original variable name of variable passed to a function

    - by Acorn
    Is it possible to get the original variable name of a variable passed to a function? E.g. foobar = "foo" def func(var): print var.origname So that: func(foobar) Returns: >>foobar EDIT: All I was trying to do was make a function like: def log(soup): f = open(varname+'.html', 'w') print >>f, soup.prettify() f.close() .. and have the function generate the filename from the name of the variable passed to it. I suppose if it's not possible I'll just have to pass the variable and the variable's name as a string each time.

  • Disk-based caching of dynamic images in IIS 7

    - by Daniel Schierbeck
    I'm writing an image server which needs to handle a relatively large number of concurrent requests (~5,000). The images being served are dynamically scaled down and cropped based on per-image specifications, which are queried from a database. The number of images is rather large, so an in-memory cache isn't viable (thrashing would most definitely occur). I'm using native caching in IIS 7 to avoid hitting the ASP.NET app which generates the images on-the-fly. I've looked around, but I couldn't find a simple way to configure IIS to store the cache on-disk -- is there such an option, or would I need to roll my own? I'd rather avoid placing the generated images in a public folder, so they can be served statically, since I would prefer to invalidate the cache entries using a query parameter (last-edit time from the database,) which doesn't seem possible to reconcile with static caching. I would love to get some feedback on this!

  • Sandbox architecture in ASP.NET?

    - by Srikanth
    Is it possible to develop a web-app in ASP.NET (framework is not a constraint), to have a sandbox architecture, and deploy widgets without disturbing the parent application? I expect both the parent application and the widget to be developed using .NET. EDIT: To elaborate, I want to have an web-app, say App1, and widgets (say wid1 and wid2). wid1 and wid2 should be like a plugin into App1, only difference is that, if I make any changes to wid1, I want to be able to deploy it without disturbing App1 or Wid2. The widgets can be something similar to a flash object, only that it needs to be developed on .net.

  • Can you expose XML webservices from a Windows Forms Application?

    - by Andrei
    This might sound like a silly question, but when I search for webservices, I get no information about how to create them in a windows forms application. The only result is how to create and expose them by creating an .aspx page. So my questions is: Can you create and expose webservices within a windows forms application or are they somehow tied in with .asp pages? Thanks! later edit: Is there an example of how to create a webservice in a .cs file and not in a .aspx file?

  • Using C++, how to call a base class method from a derived class method and apply this to an object passed as an argument?

    - by Chris
    I can't figure out how to call a base class method from a derived class method but concurrently applying this method call at an object passed as argument. What I mean is this: class Animal { virtual void eat(Animal& to_be_eaten) = 0; }; class Carnivores: public Animal { virtual void eat(Animal& to_be_eaten) { /*implementation here*/} }; class Wolf : public Carnivores { virtual void eat(Animal& to_be_eaten) { /*call eat method(of Base class) of Base to_be_eaten here*/ } } I thought of something like this dynamic_cast<Carnivores&>(to_be_eaten).eat(*this) //and got a segmentation fault Is there any way for this to be done? Thank you! New edit:: Updated the code

  • Auto generate SWF in Flex SDK

    - by Nick
    I'm building my first website with AS3, and I'm using Flash Builder 4 to create/edit my AS classes. I have two .fla files (preloader.fla and portfolio.fla) which I both published as .swc and loaded them into my ActionScript project in FB4 (build path). When I hit debug, FB4 automatically generates a .SWF in bin-debug folder called Preloader.swf, but in my Preloader.as I have new URLRequest("Portfolio.swf"); and this Portfolio.swf isn't being generated by itself. Now the real question; how can I tell FB4 to automatically create both .SWF files for me? Or isn't that possible, any workaround then? Thanks.

  • Asynchronous Processing in JBoss 6 ("Comet")

    - by chris_l
    edit: Retagged as tomcat, since this is really a question about the Tomcat embedded inside JBoss 6, rather than JBoss itself I have an extremely simple servlet, which works on Glassfish v3. It uses Servlet 3.0 Asynchronous Processing. Here's a simplified version (which doesn't do much): @WebServlet(asyncSupported=true) public class SimpleServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { final AsyncContext ac = request.startAsync(); ac.setTimeout(3000); } } On JBoss 6.0.0 (Milestone 2), I get the following Exception: java.lang.IllegalStateException: The servlet or filters that are being used by this request do not support async operation at org.apache.catalina.connector.Request.startAsync(Request.java:3096) at org.apache.catalina.connector.Request.startAsync(Request.java:3090) at org.apache.catalina.connector.RequestFacade.startAsync(RequestFacade.java:990) at playcomet.SimpleServlet.doGet(SimpleServlet.java:18) at javax.servlet.http.HttpServlet.service(HttpServlet.java:734) ... Do I have to do anything special to enable Asynchronous Processing in JBoss 6? Or do I need an additional deployment descriptor? ...

  • Missing backslashes in filename using C#

    - by CL4NCY
    Hi, I have a string literal as follows: string filename = @"C:\myfolder\myfile.jpg"; When I use File.Exists(filename) it works most of the time but sometimes I get an error saying the following file doesn't exist: C:myfoldermyfile.jpg Something seems to strip the backslashes out of the filename. This code is sometimes accessed via an ajax request. Does anyone know why/how this could be happening? Edit: Here is a more detailed version of the code. public class Feeds { public static string ftpDir = @"C:\website\Feeds\"; } public class Feed { public static void run(string name) { if (!Directory.Exists(Feeds.ftpDir + name)){ Response.Write("Feed doesn't exist '" + Feeds.ftpDir + name + "'"); return; } //run feed... } }

  • Recording object method calls to generate automated test.

    - by Constantin
    I have an object with large interface and I would like to record all its method calls done during a user session. Ideally this sequence of calls would be available as source code: myobj.MethodA(42); myobj.MethodB("spam", false); ... I would then convert this code to a test case to have a kind of automated smoke/load test. WCF Load Test can do this for WCF services and CodedUI test recorder can do this for UIs. What are my options for a POCO class? I am in position to edit application code and replace the object in question with some recording/forwarding proxy.

  • Creating a proper CMS thoughts

    - by dallasclark
    I'm just about to expand the functionality of our own CMS but was thinking of restructuring the database to make it simpler to add/edit data types and values. Currently, the CMS is quite flat - the CMS requires a field in the database for every type of stored value. The first option that comes to mind is simply a table which keeps the data types (ie: Address 1, Suburb, Email Address etc) and another table which holds values for each of these data types. Just like how Wordpress keeps values in the 'options' table, serialize would be used to store an array of values. The second option is how Drupal works, the CMS creates tables for every data type. Unlike Wordpress, this can be a bit of an overkill but really useful for SQL queries when ordering and grouping by a particular value. What's everyone's thoughts?

  • Two '==' equality operators in same 'if' condition are not working as intended.

    - by Manav MN
    I am trying to establish equality of three equal variables, but the following code is not printing the obvious true answer which it should print. Can someone explain, how the compiler is parsing the given if condition internally? #include<stdio.h> int main() { int i = 123, j = 123, k = 123; if ( i == j == k) printf("Equal\n"); else printf("NOT Equal\n"); return 0; } Output: manav@workstation:~$ gcc -Wall -pedantic calc.c calc.c: In function ‘main’: calc.c:5: warning: suggest parentheses around comparison in operand of ‘==’ manav@workstation:~$ ./a.out NOT Equal manav@workstation:~$ EDIT: Going by the answers given below, is the following statement okay to check above equality? if ( (i==j) == (j==k))

  • In LaTeX, how can one add a header/footer in the document class Letter?

    - by Brian M. Hunt
    In LaTeX, how can one create a document using the Letter documentclass, but with customized headers and footers? Typically I would use: \usepackage{fancyhdr} \pagestyle{fancy} \lhead{\footnotesize \parbox{11cm}{Custom left-head-note} } \lfoot{\footnotesize \parbox{11cm}{\textit{#2}}} \rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}} \renewcommand\headheight{24pt} \renewcommand\footrulewidth{0.4pt} However, with \documentclass{letter}, this doesn't work at all. Suggestions are duly appreciated. EDIT: Here is sample code that doesn't work (for any apparent reason): \documentclass[12pt]{letter} \usepackage{fontspec}% font selecting commands \usepackage{xunicode}% unicode character macros \usepackage{xltxtra} % some fixes/extras % page counting, header/footer \usepackage{fancyhdr} \usepackage{lastpage} \pagestyle{fancy} \lhead{\footnotesize \parbox{11cm}{Draft 1} } \lfoot{\footnotesize \parbox{11cm}{\textit{2}}} \cfoot{} \rhead{\footnotesize 3} \rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}} \renewcommand{\headheight}{24pt} \renewcommand{\footrulewidth}{0.4pt} \begin{document} \name{ Joe Laroo } \signature{ Joe Laroo } \begin{letter}{ To-Address } \renewcommand{\today}{ February 16, 2009 } \opening{ Opening } Content of the letter. \closing{ Yours truly, } \end{letter} \end{document}

  • Routing a location that matches one controller to another

  • How do I open a web browser from a .NET Program? Process.Start() isn't working?

    - by Scott Whitlock
    I have a URL and I want to launch it in the default browser. I've tried two methods: Process.Start("http://stackoverflow.com"); ... and the one detailed in this other question using ShellExecute. In both cases I get the error: Windows cannot find 'http://stackoverflow.com'. Make sure you typed the name correctly, and then try again. It shouldn't be trying to open it as a file though... from what I understand, it should recognize it as a URL and open it in the default browser. What am I missing? By the way: OS = Vista, and .NET = 3.5 EDIT: According to this MS KB article, since Process.Start sets the UseShellExecute by default, it should launch the default browser.

  • Can't Reorder a UITableViewCell into _some_ empty sections of a UITableView

    - by Jeremy Lightsmith
    If I have a UITableView in edit mode, w/ reordering turned on, it seems I can't move some (but not all) cells into some (but not all) empty sections. For example, if I have this layout : Section 1 apple banana Section 2 doberman Section 3 Section 4 Then I can move 'doberman' into any slot in section 1 (except after 'banana'), but I can't move it into section 3 or 4 at all. On the other hand, I can move 'apple' & 'banana' into section section 2 (except after 'doberman'), and I CAN move it into section 3, but NOT into section 4. What gives? this seems like buggy behavior. How do people work around it? Is apple aware of this bug?

  • Getting data back from database after an ajax post submit

    - by sslepian
    I've got a web page where the user can add a new item to a category and that item is saved to the database. However, the ID of the item is an identity value for the database table, so I don't know what the ID will be, and I need this ID so that the user can edit the item later. I'm using ajax to make a POST submit: $.ajax({ url: 'TumourGroup/CreateSub', type: "POST", data: {'pos': index, 'text': text } }); This is linked to an MVC model with three fields, ID, pos, and text. Is there a way for me to get the ID that's generated on POST submit by having CreateSub(int index, string text) return something?

  • Is there a way to tell Drupal not to cache a specific page?

    - by TechplexEngineer
    I have a custom php page that processes a feed of images and makes albums out of it. However whenever i add pictures to my feed, the Drupal page doesn't change until I clear the caches. Is there a way to tell Drupal not to cache that specific page? Thanks, Blake Edit: Drupal v6.15 Not exactly sure what you mean oswald, team2648.com/media is hte page.

  • How to read a file byte by byte in Python and how to print a bytelist as a binary?

    - by zaplec
    Hi, I'm trying to read a file byte by byte, but I'm not sure how to do that. I'm trying to do it like that: file = open(filename, 'rb') while 1: byte = file.read(8) # Do something... So does that make the variable byte to contain 8 next bits at the beginning of every loop? It doesn't matter what those bytes really are. The only thing that matters is that I need to read a file in 8-bit stacks. EDIT: Also I collect those bytes in a list and I would like to print them so that they don't print out as ASCII characters, but as raw bytes i.e. when I print that bytelist it gives the result as ['10010101', '00011100', .... ]
