  • DeleteOnSubmit doesnt exist?

    - by Anders Metnik
    using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data; Thats my namespaces.. i was looking for System.Data.Linq; but it doesnt seem to be anywhere, and i guess that is what have been moved to System.Linq, since i have access to most other things in Linq. EDIT: found System.Data:Linq, no difference Here is my method: public void deleteStudienummer(int studienummer) { dbcontent = new DBEntities(); var dQry = from members in dbcontent.Medlemmer where members.Studienummer == studienummer select members; foreach (var member in dQry) { dbcontent.*** } dbcontent.AcceptAllChanges(); Console.WriteLine("delete member should have occured"); } The * was supposed to be DeleteOnSubmit, but i only have DeleteDatabase and DeleteObject, i tried with object but it doesnt work.. Have also tried dbcontent.Medlemmer.* but still not present. And AcceptAllChanges() was supposed to be .submitChanges() but that wasnt present either.

  • What should a hobbyist do to develop good programming skills after basics?

    - by thyrgle
    So I'll say right here that I'm no professional coder. I'm a hobbyist. And pretty much like other people I feel like I'm doing it wrong. Like this question A feeling that I'm not a good programmer if have began to feel like that. Now I know basically that they say you shouldn't worry and that your good even if you continuously doubt yourself. But, they are talking to him. I'm not like him (in the sense I'm more of a newbie)... I've been coding as a hobbyist for 3 years (3 hobbyist years mind you!) unlike his 10-11 years that he states. Also, the only thing I've probably read in-depth is Teach Yourself C++ in 21 Days. And before I continue, just so your not confused about the various questions I've posted on (mostly) iPhone and OpenGL, I have poked and prodded at those two things for a few months each and finally sort of got a hang of both of them. But, from what I've noticed, is that I suck at making good code. For me its not even a debate of whether I'm doing it wrong or not: I can tell (from the various spaghetti code I create and other various discrepancies I, and others, can see and have noted in my code). What is a good way to get rid of these awful habits of mine and do it in a more correct, or if there is no "correct way" then I mean "typical", way?

  • Error 1009 after gotoAndStop - stage instance never gets added

    - by ELambda
    I've been through the forums for hours (days?) searching on 1009 errors, but I remain stumped on this. It seems very mysterious and I would LOVE some help if you have any ideas. I have a single .swf that is 7 frames long - each frame represents a different "page" and you can switch pages through a menu widget in the top right corner. The menu widget calls gotoAndPlay( "frame" ). Everything works fine except when I switch from one particular frame to another. Then, during initialization of the new frame (setting some visible properties on various items, in actionscript), I get the dreaded 1009 error on a specific stage instance, a dynamic text instance i_word. Here's what I've tried so far: made sure the actionscript for the new frame starts with a stop() statement before starting initialization - no dice tried changing i_word into a movie_clip instead of dynamic text, made sure it was exported for actionscript - no difference. (I also have 2 other dynamic text instances on the same page that don't seem to cause a problem) added an ENTER_FRAME listener when the new frame is loaded, in case the problem was a timing issue. Put in a big if statement checking if i_word and other instances are not null before proceeding to initialization. It never enters the if, because i_word NEVER gets added. I added trace statements for all instances that are null, and it is the only one. If I remove all references to i_word in my actionscript, everything else is not null, and things go forward. The text for i_word even shows up on the screen in that case. tried renaming i_word - no dice tried deleting the layer i_word was on and adding a new layer - no dice It feels like there is a serious Gremlin in my flash file somewhere. Or maybe I'm missing something obvious. Let me know if you have any ideas...I'd be so grateful. Thank you! Elambda

  • Execute JavaScript from within a C# assembly

    - by ScottKoon
    I'd like to execute JavaScript code from within a C# assembly and have the results of the JavaScript code returned to the calling C# code. It's easier to define things that I'm not trying to do: I'm not trying to call a JavaScript function on a web page from my code behind. I'm not trying to load a WebBrowser control. I don't want to have the JavaScript perform an AJAX call to a server. What I want to do is write unit tests in JavaScript and have then unit tests output JSON, even plain text would be fine. Then I want to have a generic C# class/executible that can load the file containing the JS, run the JS unit tests, scrap/load the results, and return a pass/fail with details during a post-build task. I think it's possible using the old ActiveX ScriptControl, but it seems like there ought to be a .NET way to do this without using SilverLight, the DLR, or anything else that hasn't shipped yet. Anyone have any ideas? update: From Brad Abrams blog namespace Microsoft.JScript.Vsa { [Obsolete("There is no replacement for this feature. Please see the ICodeCompiler documentation for additional help. http://go.microsoft.com/fwlink/?linkid=14202")] Clarification: We have unit tests for our JavaScript functions that are written in JavaScript using the JSUnit framework. Right now during our build process, we have to manually load a web page and click a button to ensure that all of the JavaScript unit tests pass. I'd like to be able to execute the tests during the post-build process when our automated C# unit tests are run and report the success/failure alongside of out C# unit tests and use them as an indicator as to whether or not the build is broken.

  • Move and rename file in android

    - by Andre Fróes
    I am trying to copy a file to another folder in the android, but so far, i got no success. I manage to do so with a selected image and when taking a photo, but not with files. I've read and tried several solutions passed by the community (searched over the forum and the internet), but none of it was able to solve my problem when copying. First things first. I added the permissions to my manifest: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> after that, before copying a file, i print its filepath and the directory file path: 06-10 11:11:11.700: I/System.out(1442): /mimetype/storage/sdcard/Misc/Javascript erros for Submit and Plan buttons in IE.doc 06-10 11:11:11.710: I/System.out(1442): /storage/sdcard/mywfm/checklist-files both exists: to copy the file to the expected folder I used the FileUtils: try { FileUtils.copyFile(selectedFile, dir); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } The problem is: I get no exception and the file isn't there. I tried this solution either: How to move/rename file from internal app storage to external storage on Android? same thing, no exception, but no file either.

  • Running an application from an USB device...

    - by Workshop Alex
    I'm working on a proof-of-concept application, containing a WCF service with console host and client, both on a single USB device. On the same device I will also have the client application which will connect to this service. The service uses the entity framework to connect to the database, which in this POC will just return a list of names. If it works, it will be used for a larger project. Creating the client and service was easy and this works well from USB. But getting the service to connect to the database isn't. I've found this site, suggesting that I should modify machine.config but that stops the XCopy deployment. This project cannot change any setting of the PC, so this suggestion is bad. I cannot create a deployment setup either. The whole thing just needs to run from USB disk. So, how do I get it to run? (The service just selects a list of names from the database, which it returns to the client. If this POC works, it will do far more complex things!)

  • Should I *always* import my file references into the database in drupal?

    - by sprugman
    I have a cck type with an image field, and a unique_id text field. The file name of the image is based on the unique_id. All of the content, including the image itself is being generated automatically via another process, and I'm parsing what that generates into nodes. Rather than creating separate fields for the id and the image, and doing an official import of the image into the files table, I'm tempted to only create the id field and create the file reference in the theme layer. I can think of pros and cons: 1) Theme Layer Approach Pros: makes the import process much less complex don't have to worry about syncing the db with the file system as things change more flexible -- I can move my images around more easily if I want Cons: maybe not as much The Drupal Way™ not as pure -- I'll wind up with more logic on the theme side. 2) Import Approach Pros: import method is required if we ever wanted to make the files private (we won't.) safer? Maybe I'll know if there's a problem with the image at import time, rather than view time. Since I'll be bulk importing, that might make a difference. if I delete a node through the admin interface, drupal might be able to delete the file for me, as well. Con: more complex import and maintenance All else being equal, simpler is always better, so I'm leaning toward #1. Are there any other issues I'm missing? (Since this is an open ended question, I guess I'll make it a community wiki, whatever that means.)

  • VSTO Outlook - Contact iteration is SO SLOW!

    - by DustinDavis
    I'm working on an outlook add-in and I have a dialog window that allows the user to select contacts. I havent been able to find a way to use the outlook contact window so I am looping through the ContactFolder.Items and doing my work that way. The problem is that I have to handle up to 70K contacts. I tried multi-threading and many other things but it is just so slow. It takes 15 seconds to load 30k contacts. I can load and bind 500k POCO objects in milliseconds but when I need to get the contact items from outlook it just takes forever. The problem seems to be when you actually need to get a property from the contactitem it has to fetch it from the database or something. Is there a contact cache I can pull from? I only need Display and Email, nothing else. An ID would be nice but I don't need it. Can someone please tell me a better way of getting contacts from outlook or at least tell me how to open the outlook contact selection window? I was able to find code to open it but it wont let me because I'm showing a modal dialog and it wont open if there is a modal open.

  • Question about array subscripting in C#

    - by Michael J
    Back in the old days of C, one could use array subscripting to address storage in very useful ways. For example, one could declare an array as such. This array represents an EEPROM image with 8 bit words. BYTE eepromImage[1024] = { ... }; And later refer to that array as if it were really multi-dimensional storage BYTE mpuImage[2][512] = eepromImage; I'm sure I have the syntax wrong, but I hope you get the idea. Anyway, this projected a two dimension image of what is really single dimensional storage. The two dimensional projection represents the EEPROM image when loaded into the memory of an MPU with 16 bit words. In C one could reference the storage multi-dimensionaly and change values and the changed values would show up in the real (single dimension) storage almost as if by magic. Is it possible to do this same thing using C#? Our current solution uses multiple arrays and event handlers to keep things synchronized. This kind of works but it is additional complexity that we would like to avoid if there is a better way.

  • How do I force MyEclipse to hot-deploy a JavaScript file to my JBoss instance?

    - by Mike Cialowicz
    I'm having trouble with MyEclipse 7.1.1 hot-deployment of files to my JBoss 4 server. The problem is this: while my server is running, I can make changes to various JAVA and HTML files, which are then hot-deployed immediately (I can see the changes reflected in my browser when I refresh the page). However, while working on a particular JavaScript file, my changes are not being hot-deployed. This makes it very difficult to work on and debug this file, since I have to stop my server, redeploy, and start it again each time I make changes. This is a new problem - it didn't used to happen with this file, so I think something got screwed up in my MyEclipse configuration. I've verified that my projects (JBoss 4 instances) are all set up in "Exploded" mode for hot-deployment. I'm also 99% sure that this isn't an issue with my browser, since I always refresh with CTRL+F5, and I've tried a number of things like clearing my browser cache to get the currently deployed version of the file. I've also tried doing a "clean" on the project while the server is running, and that didn't force a deployment either. Any sort of solution would be helpful. I'd love for MyEclipse to deploy the file automatically, but I'm also open to manually forcing hot-deployment of this particular file while I work on it. Thank you.

  • Updating a C# 2.0 events example to be idiomatic with C# 3.5?

    - by Damien Wildfire
    I have a short events example from .NET 2.0 that I've been using as a reference point for a while. We're now upgrading to 3.5, though, and I'm not clear on the most idiomatic way to do things. How would this simple events example get updated to reflect idioms that are now available in .NET 3.5? // Args class. public class TickArgs : EventArgs { private DateTime TimeNow; public DateTime Time { set { TimeNow = value; } get { return this.TimeNow; } } } // Producer class that generates events. public class Metronome { public event TickHandler Tick; public delegate void TickHandler(Metronome m, TickArgs e); public void Start() { while (true) { System.Threading.Thread.Sleep(3000); if (Tick != null) { TickArgs t = new TickArgs(); t.Time = DateTime.Now; Tick(this, t); } } } } // Consumer class that listens for events. public class Listener { public void Subscribe(Metronome m) { m.Tick += new Metronome.TickHandler(HeardIt); } private void HeardIt(Metronome m, TickArgs e) { System.Console.WriteLine("HEARD IT AT {0}",e.Time); } } // Example. public class Test { static void Main() { Metronome m = new Metronome(); Listener l = new Listener(); l.Subscribe(m); m.Start(); } }

  • What are the drawbacks of this Classing format?

    - by Keysle
    This is a 3 layer example of my classing format function __(_){return _.constructor} //class var _ = ( CLASS = function(){ this.variable = 0; this.sub = new CLASS.SUBCLASS(); }).prototype; _.func = function(){ alert('lvl'+this.variable); this.sub.func(); } _.divePeak = function(){ alert('lvl'+this.variable); this.sub.variable += 5; } //sub class _ = ( __(_).SUBCLASS = function(){ this.variable = 1; this.sub = new CLASS.SUBCLASS.DEEPCLASS(); }).prototype; _.func = function(){ alert('lvl'+this.variable); this.sub.func(); } //deep class _ = ( __(_).DEEPCLASS = function(){ this.variable = 2; }).prototype; _.func = function(){ alert('lvl'+this.variable); } Before you blow a gasket, let me explain myself. The purpose behind the underscores is to accelerate the time needed to specify functions for a class and also specify sub classes of a class. To me it's easier to read. I KNOW, this does interfere with underscore.js if you intend to use it in your classes. I'm sure _.js can be easily switched over to another $ymbol though ... oh wait, But I digress. Why have classes within a class? because solar.system() and social.system() mean two totally different things but it's convenient to use the same name. Why user underscores to manage the definition of the class? because "Solar.System.prototype" took me about 2 seconds to type out and 2 typos to correct. It also keeps all function names for all classes in the same column of texts, which is nice for legibility. All I'm doing is presenting my reasoning behind this method and why I came up with it. I'm 3 days into learning OO JS and I am very willing to accept that I might have messed up.

  • Is programming overrated?

    - by aengine
    [Subjective and intended to be a community wiki] I am sorry for such an offensive question: But here are my arguments Most of the progress in "computing" has came from non-programming sources. i.e. People invented faster microprocessors and better routers and novel memory devices. I dont think on average people are writting more efficient programs than those written 10 years ago. And the newer and popular languages are infact slower than C. though speed is one of the lesser criterias. Most of the progress came from novel paradigms. Web, Internet, Cloud computing and Social networking are novel paradigms and did not involve progress in programming as such. Heck even facebook was written in PHP and not some extreme language. Though it did face scalability issues (same with twitter) but i believe money and better programmers (who came in much later) took care of that. Thus ideating capability trumped programming capability/ Even things like Map-Reduce, Column oriented database and Probablistic algorithms (E.g. bloom filters) came from hardcore Algorithms research, rather than some programming convention. Thus my final point is why programming skill is so overstressed? To point a recent example about how only 10% of programmers can "write code" (binary search) without debugging. Isnt it a bit hypocritical, considering your real successs lies in coming up with better algorithm or a novel feature rather than getting right first time???

  • Can anyone recommend a payment processing script or service that is as (nearly?) as convenient and c

    - by Jason Livesay
    I have been going through all of the different PayPal integration options and trying to decide which will be the best one for this particular application. I realized that I really want to give users a few options for payment. For example, it might be more convenient to enter their credit card information rather than being sent over to PayPal, or they may have already setup their Google Checkout and so want to use that. So that brings me fairly quickly to the realization that maybe I don't want to program one or two or three API integrations myself and I should look at some shopping cart software. However, we really don't need a whole shopping cart -- we will have a specific form and some other custom coding and the only part of the shopping cart we would really use would be the checkout page to handle accepting payment/integrating with PayPal/Google Checkout/Authorize.net. I like how simple eJunkie makes things and the fact that it accepts PayPal and Google Checkout and Authorize.net. The problem is that the Add To Cart buttons aren't going to cut it. I need to be able to programmatically enter items into the cart. Maybe I can just use an open source PHP shopping cart and skip the store front somehow.

  • WPF/Silverlight Resources for Businesses

    - by Refracted Paladin
    I am the only developer at a non-profit organization(~200 employees) where we are a M$ shop and 90% of the things I develop are specific to our company and are internal only. I am given a lot of latitude on how I accomplish my goals so using new technologies is in my best interest. So far I have developed all winform & asp.net applications. I would now like to focus on XAML driven development(WPF & Silverlight) and would like your help. I am subscribed to numerous Silverlight blogs and I have went through a few good tutorials however, I would really appreciate a GOOD SOLID book in my hands going forward. I prefer learning books versus reference books and I REALLY would like one from a Business standpoint as well. Shameless, self-promoting is welcomed if you happen to be an author or reviewer for one that meets my criteria. I would, however, prefer that recomendations were based on first-hand experience(no, 'my friend as this awesome book he told me about', please). Though, I don't mind un-released books if say they are an updated version of an existing. If more info is needed to provide accurate recomendations please let me know. Thanks disclaimer -- I know there are an insane amount of Book posts here(SO) but none I believe for my specific need. If there is and I missed it I apologize.

  • Using VB6 to search for existence of DataFile in Outlook

    - by Graeme
    Hi, I am wanting to write an Add-In for Outlook 2003 which, when Outlook is opened, search for the existence of a datafile called DMSDataStore and if it doesn't exist will install the datafile. I have managed to create the Add-In using VB6 and it runs when I open Outlook. However I haven't found the best/easiest way to search for the existence of the datafile. If the datafile exists it is visible within Outlook under the user's mailbox, much the same as an archive folder is. I would like to be able to search for it by name which is DMSDataFile. I did try - Set tmpInbox = parentFolder.Folders("DMSDataFile") This works OK if the datafile exists but will throw an error if it doesn't. I can create an error handler which will then install the datafile but this doesn't seem like a very tidy way of doing things. I guess I might have to recursively search for the datafile. Can someone let me know what is the best / easiest way to search for the datafile using the name of the datafile and give me some code with which to do it. Thanks G

  • codeigniter cron job with http access

    - by user1313850
    Sorry if this is a duplicate question...I've searched around and found similar advice but nothing that helps my exact problem. And please excuse the noob questions, CRON is a new thing for me. I have a codeigniter script that scrapes the html DOM of another site and stores some of that in a database. I'd like to run this script at a regular interval. This has lead me to looking into cron jobs. The page I have is at myserver.com/index.php/update I realize I can run a cron job with curl and run this page. If I want to be a bit more secure I can put a string at the end like: myserver.com/index.php/update/asdfh2784fufds And check for that in my CI controller. This seems like it would be mostly secure, but doesn't seem like the "right" way to do things. I've looked into running CI from the command line, and can execute basic pages like: php index.php mycontroller But when I try to do: php index.php update It doesn't work. I suspect this is because it needs to use HTTP to scrape the DOM of the outside page. So, my question: How do I securely run a codeigniter script with a cron job that needs HTTP access?

  • sort elements in jQuery object

I also looked at making a new blank jquery object that I could pass elements into like this $newObjectVar.eq(0) = $myClass.eq(3); for example. But as of yet I have not found a way to make a blank jQuery object like this.

  • A question of long-running and disruptive branches

    - by Matt Enright
    We are about to begin prototyping a new application that will share some existing infrastructure assemblies with an existing application, and also involve a significant subset of the existing domain model. Parts of the domain model will likely undergo some serious changes for this new application, and the endgame for all of this, once the new application has been fully specified and is launch-ready is that we would like to re-unify the models of the two applications (as well as share a database, link functionality, etc.), but for the duration of development, prototyping, etc, we will be using a separate database so that we can change things without worrying about impact to development or use of the existing application. Since it is a prototype, there will be a pretty long window during which serious changes or rearchitecturing can occur as product management experiments with different workflows, different customer bases are surveyed, and we try and keep up. We have already made a Subversion branch, so as to not impact concurrent development on the mature application, and are toying with 2 potential ways of moving forward with this: Use the svn branch as the sole mechanism of separation. Make our changes to the existing domain models, and evaluate their impact on the existing application (and make requisite changes to ProjectA) when we have established that our long-running side branch is stable enough for re-entry to trunk. "Fork" the shared code (temporarily): Copy ProjectA.Entities to NewProject.Entities, and treat all of the NewProject code as self-contained. When all of the perturbations around the model have died down and we feel satisfied, manually re-integrate the changes (as granular or sweeping as warranted) back into ProjectA.Entities, updating ProjectA to use the improved models at each step (this can take place either before or after the subversion merge has occurred). The subversion merge will then not handle recombination of any of the heavy changes here. Note: the "fork" method only applies to the code we see significant changes in store for, and whose modification will break ProjectA - shared infrastructure stuff for example, we would just modify in place (on our branch) and let the merge sort out. Development is hard, go shopping. Naturally, after not coming to an agreement, we're turning it over to the oracle of power that is SO. Any experience with any of these methods, pain points to watch out for, something new entirely?

  • Running a process at the Windows 7 Welcome Screen

    - by peelman
    So here's the scoop: I wrote a tiny C# app a while back that displays the hostname, ip address, imaged date, thaw status (we use DeepFreeze), current domain, and the current date/time, to display on the welcome screen of our Windows 7 lab machines. This was to replace our previous information block, which was set statically at startup and actually embedded text into the background, with something a little more dynamic and functional. The app uses a Timer to update the ip address, deepfreeze status, and clock every second, and it checks to see if a user has logged in and kills itself when it detects such a condition. If we just run it, via our startup script (set via group policy), it holds the script open and the machine never makes it to the login prompt. If we use something like the start or cmd commands to start it off under a separate shell/process, it runs until the startup script finishes, at which point Windows seems to clean up any and all child processes of the script. We're currently able to bypass that using psexec -s -d -i -x to fire it off, which lets it persist after the startup script is completed, but can be incredibly slow, adding anywhere between 5 seconds and over a minute to our startup time. We have experimented with using another C# app to start the process, via the Process class, using WMI Calls (Win32_Process and Win32_ProcessStartup) with various startup flags, etc, but all end with the same result of the script finishing and the info block process getting killed. I tinkered with rewriting the app as a service, but services were never designed to interact with the desktop, let alone the login window, and getting things operating in the right context never really seemed to work out. So for the question: Does anybody have a good way to accomplish this? Launch a task so that it would be independent of the startup script and run on top of the welcome screen?

  • Can I strictly evaluate a boolean expression stored as a string in Java?

    - by D Lawson
    I would like to be able to evaluate an boolean expression stored as a string, like the following: "hello" == "goodbye" && 100 < 101 I know that there are tons of questions like this on SO already, but I'm asking this one because I've tried the most common answer to this question, BeanShell, and it allows for the evaluation of statements like this one "hello" == 100 with no trouble at all. Does anyone know of a FOSS parser that throws errors for things like operand mismatch? Or is there a setting in BeanShell that will help me out? I've already tried Interpreter.setStrictJava(true). Here's the code that I'm using currently: Interpreter interpreter = new Interpreter(); interpreter.setStrictJava(true); String testableCondition = "100 == \"hello\""; try { interpreter.eval("boolean result = ("+ testableCondition + ")"); System.out.println("result: "+interpreter.get("result")); if(interpreter.get("result") == null){ throw new ValidationFailure("Result was null"); } } catch (EvalError e) { e.printStackTrace(); throw new ValidationFailure("Eval error while parsing the condition"); }

In the real code it packages the function for a thread to execute. func would the function executed by the other thread, doit sits in between to check for unhandled exceptions and to clean up. But the additional bind in func_wrapper messes things up...

  • Maven build issue with Hibernate for Windows

    - by wishi_
    Hi! I'm getting build errors for for my Maven enabled project related to the Hibernate extension. - It's a very basic app, and I was able to solve this issue on my Linux box by manually installing some required artifacts: mvn install:install-file -DgroupId=javassist -DartifactId=javassist -Dversion=3.9.0 -Dpackaging=jar -Dfile=foo.jar That worked out (Hibernate as a set of required deps). But in case of Windows things are different. How do I add the dependencies manually to Maven on Windows? 1) org.hibernate:hibernate:jar:3.3.2 Try downloading the file manually from the project website. Then, install it using the command: mvn install:install-file -DgroupId=org.hibernate -DartifactId=hibernate -Dversion=3.3.2 -Dpackaging=jar -Dfile=/path/to/file 2) javassist:javassist:jar:3.9.0 Can I automate this cumbersome manual dependency installation for my coworkers on their Windows machines? Are there any helpful tools or GUI that can perform these tasks? The best way would be that Maven does it all automatically. I'm not too familiar with it jet. Thanks for answers.

  • Font for tabs looks a little too big

    - by cf_PhillipSenn
    I'm using the default for jQueryUI, but it looks like the font is a little big. I know that one solution would be "WELL! JUST MAKE IT SMALLER!", but I'm just wondering if I've messed something up or I don't have a value set correctly before I charge in and start changing things. <!DOCTYPE HTML> <html> <head> <script src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1"); </script> <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1/themes/smoothness/jquery-ui.css" type="text/css" media="all" /> <script type="text/javascript"> google.load("jqueryui", "1"); function OnLoadCallbackUI(){ $('#tabs').tabs(); } google.setOnLoadCallback(OnLoadCallbackUI); </script> </head> <body> <div id="tabs"> <ul> <li><a href="#tabs-1">tab1</a></li> <li><a href="#tabs-2">tab2</a></li> </ul> <div id="tabs-1"> tabs-1 </div> <div id="tabs-2"> tabs-2 </div> </div> </body> </html>

  • Problem in mutiple :dependent=> :destroy when multiple polymorphic is true

    - by piemesons
    I have four models question, answer, comment and vote.Consider it same as stackoverflow. Question has_many comments Answers has_many comments Questions has_many votes answers has_many votes comments has_many votes Here are the models (only relevant things) class Comment < ActiveRecord::Base belongs_to :commentable, :polymorphic => true has_many :votes, :as => :votable, :dependent => :destroy end class Question < ActiveRecord::Base has_many :comments, :as => :commentable, :dependent => :destroy has_many :answers, :dependent => :destroy has_many :votes, :as => :votable, :dependent => :destroy end class Vote < ActiveRecord::Base belongs_to :votable, :polymorphic => true end class Answer < ActiveRecord::Base belongs_to :question, :counter_cache => true has_many :comments, :as => :commentable , :dependent => :destroy end Now the problem is whenever i am trying to delete any question/answer/comment its giving me an error NoMethodError in QuestionsController#destroy undefined method `each' for 0:Fixnum if i remove this line from any of the model (question/answer/comment) has_many :votes, :as => :votable, :dependent => :destroy then it works perfectly. It seems there is a problem while deleting the records active record is not able to find out the proper path because of multiple joins within the tables.
