• Filtering foreign keys with AJAX in Django admin

  - by cnobile

  I have most of this figured out already. I have AJAX returning the region/state/province when a country is selected. The correct foreign key is saved to the database, however, when the record is viewed afterwards the selected state is not shown in the select nor are any states for the selected country. I understand why this is happening as, the admin view is not aware of the relation between the state and the country. So here is the question. Is there a hook in the admin view that will allow me to load the correct states for the country and set the selected attribute on the option in the select tag? Or how can I override the admin view for any forms that require the country and region/state/province set? I am using jQuery and Djando-1.1. Thanks

• xml and external swf documents

  - by VideoDnd

  My XML scripts work fine in the local swf. If I load an external swf, can I still retreive XML data from the same way, or do I have to declare the root somewhere? It's a general question. I know that when animating external swf files, you have to set it up differently, if so I would like an example, and a pitcher of beer. It's St. Patrick's weekend. SAMPLE CODE ONLY XML <?xml version="1.0" encoding="utf-8"?> <SESSION> <COUNT TITLE="starting position">-77777</COUNT> </SESSION> loader swf 'nodes' //grab the data as a string myString = myXML.COUNT.text(); //grab the data as an int count = int(myXML.COUNT.text()); external swf 'variables' var myString:String = ""; var count:int = int(myString); trace(count);

• Can Qt's QWebView display programatically generated XML?

  - by Dan Ellis

  Using Qt 4.6, I can dynamically add to an HTML page like this: ui->webView->page()->mainFrame()->documentElement().findFirst("body").appendInside("<i>some text</i>\n"); However, if I QWebView::load() an XML file, it displays it with the correct CSS styling (from an processing instruction), but doesn't show any changes when I do something like: ui->webView->page()->mainFrame()->documentElement().findFirst("lines").appendInside("<line>hello</line>\n"); Why is it treating them differently, and is there a way to modify an XML document in the same way I can an HTML one?

• Android Show Map location when Longitude/ Latitude values are in DMS Format

  - by JibW

  In my Android application I need to load Google map and show the location according to the Latitude and the Longitude values provided. I referred the following tutorial and its completely ok. Work fine. Link to the tutorial I followed Problem is Latitude and Longitude values are stored in SQLite database in the DMS Fromat. If those values were in the Decimal Degrees format then No problem, as I can do the way it was in that tutorial. I need to Show the exact place by adding Overlay Item(I have given the Longitude and Latitude values by DMS Format). [Example values: 36°7'59''N, 5°25'59''W] Thanks...

• Rails 3 jQuery UI Slider

  - by Tyler DeWitt

  I'm trying to use the jQuery UI Slider with my rails 3 app. I've downloaded a theme and put the css file in app/assets/stylesheet and I put all the images in app/assets/images. When I load a page with a slider, I get an error that it can't find an image: GET http://10.1.10.100:3000/assets/images/ui-bg_glass_45_0078ae_1x400.png 404 (Not Found) That file is in app/assets/images/ and the css file has been edited to point to ../images/<image> Is there something else I need to do to make a jQuery slider work with Rails 3? gist with the files: https://gist.github.com/2355571

• EXC_BAD_ACCESS at UITableView on IOS

  - by Suprie

  Hi all, When scrolling through table, my application crash and console said it was EXC_BAD_ACCESS.

• Can rails test speed be increased?

  - by Sam

  Hi all, I'm a recent convert to TDD but as my codebase grows in size and complexity, I find myself waiting longer and longer periods for the framework to load every time I want to run a test. I am aware of rspec's spec_server but I'm using Test::Unit with shoulda. I tried Snailgun (http://github.com/candlerb/snailgun) but noticed very little increased in speed. I have also tried spork-testunit (http://github.com/timcharper/spork-testunit) but it's not fully compatible with my existing tests. The delay in running tests is a definite pain point and is putting me of TDD (at least with rails). Is anyone aware of any other options? thanks Sam

• Application_End() cannot access cache through HttpContext.Current.Cache[key]

  - by Carl J.

  I want to be able to maintain certain objects between application restarts. To do that, I want to write specific cached items out to disk in Global.asax Application_End() function and re-load them back on Application_Start(). I currently have a cache helper class, which uses the following method to return the cached value: return HttpContext.Current.Cache[key]; Problem: during Application_End(), HttpContext.Current is null since there is no web request (it's an automated cleanup procedure) - therefore, I cannot access .Cache[] to retrieve any of the items to save to disk. Question: how can I access the cache items during Application_End()?

• A controller method that calls a different method on the same controller

  - by justSteve

  I have a controller method: public ActionResult Details(int id) { Order order = OrderFacade.Instance.Load(id); return View(order); } that is used for 95% of possible invocations. For the other 5% i need to manipulate the value of id before passing to the facade. I'd like to create a separate method within this same controller that executes that manipulation and then calls this (Details) method. What would the signature of that method look like? What is the syntax to call the main Details method? public ??? ManipulatorMethod(int id) { [stuff that manipulates id] [syntax to call Details(manipulatedID)] } mny thx

• How should I build a privacy drop-down (select) menu?

  - by animuson

  I'm trying to build something similar to Facebook's privacy selection menu, except without the 'custom' option. It will only list a few options such as 'show to all', 'show to friends only', or 'completely hidden'. Right now I'm thinking of using simple JavaScript to change a hidden input field to the new value they click on, so if they clicked on the division for 'show to friends only' it would change the corresponding field, say 'email_privacy', to 1. Is there a better way to do this or am I pretty much on track? P.S. I am not planning on using a select element, I was planning on building a custom drop-down menu using CSS since select elements are so highly non-customizable. I'm doing it this way to save space, rather than having this massive selection menu at the right which takes up a bunch of space. Note: I'm not really interested in using jQuery, that's just extra libraries and crap that I don't want to load. I can do it in JavaScript just as easily so I might as well use that.

• Preventing symbols from being stripped in IBM Visual Age C/C++ for AIX

  - by smountcastle

  I'm building a shared library which I dynamically load (using dlopen) into my AIX application using IBM's VisualAge C/C++ compiler. Unfortunately, it appears to be stripping out necessary symbols: rtld: 0712-002 fatal error: exiting. rtld: 0712-001 Symbol setVersion__Q2_3CIF17VersionReporterFRCQ2_3std12basic_stringXTcTQ2_3std11char_traitsXTc_TQ2_3std9allocatorXTc__ was referenced from module ./object/AIX-6.1-ppc/plugins/plugin.so(), but a runtime definition of the symbol was not found. Both the shared library and the application which loads the shared library compile/link against the static library which contains the VersionReporter mentioned in the error message. To link the shared library I'm using these options: -bM:SRE -bnoentry -bexpall To link the application, I'm using this option: -brtl Is there an option I can use to prevent this symbol from being stripped in the application? I've tried using -nogc as stated in the IBM docs, but that causes the shared library to be in an invalid format or the application to fail to link (depending on which one I use it with).

• HLSL/XNA Ambient light texture mixed up with multi pass lighting

  - by Manu-EPITA

  I've been having some troubles lately with lighting. I have found a source on google which is working pretty good on the example. However, when I try to implement it to my current project, I am getting some very weird bugs. The main one is that my textures are "mixed up" when I only activate the ambient light, which means that a model gets the texture of another one . I am using the same effect for every meshes of my models. I guess this could be the problem, but I don't really know how to "reset" an effect for a new model. Is it possible? Here is my shader: float4x4 WVP; float4x4 WVP; float3x3 World; float3 Ke; float3 Ka; float3 Kd; float3 Ks; float specularPower; float3 globalAmbient; float3 lightColor; float3 eyePosition; float3 lightDirection; float3 lightPosition; float spotPower; texture2D Texture; sampler2D texSampler = sampler_state { Texture = <Texture>; MinFilter = anisotropic; MagFilter = anisotropic; MipFilter = linear; MaxAnisotropy = 16; }; struct VertexShaderInput { float4 Position : POSITION0; float2 Texture : TEXCOORD0; float3 Normal : NORMAL0; }; struct VertexShaderOutput { float4 Position : POSITION0; float2 Texture : TEXCOORD0; float3 PositionO: TEXCOORD1; float3 Normal : NORMAL0; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; output.Position = mul(input.Position, WVP); output.Normal = input.Normal; output.PositionO = input.Position.xyz; output.Texture = input.Texture; return output; } float4 PSAmbient(VertexShaderOutput input) : COLOR0 { return float4(Ka*globalAmbient + Ke,1) * tex2D(texSampler,input.Texture); } float4 PSDirectionalLight(VertexShaderOutput input) : COLOR0 { //Difuze float3 L = normalize(-lightDirection); float diffuseLight = max(dot(input.Normal,L), 0); float3 diffuse = Kd*lightColor*diffuseLight; //Specular float3 V = normalize(eyePosition - input.PositionO); float3 H = normalize(L + V); float specularLight = pow(max(dot(input.Normal,H),0),specularPower); if(diffuseLight<=0) specularLight=0; float3 specular = Ks * lightColor * specularLight; //sum all light components float3 light = diffuse + specular; return float4(light,1) * tex2D(texSampler,input.Texture); } technique MultiPassLight { pass Ambient { VertexShader = compile vs_3_0 VertexShaderFunction(); PixelShader = compile ps_3_0 PSAmbient(); } pass Directional { PixelShader = compile ps_3_0 PSDirectionalLight(); } } And here is how I actually apply my effects: public void ApplyLights(ModelMesh mesh, Matrix world, Texture2D modelTexture, Camera camera, Effect effect, GraphicsDevice graphicsDevice) { graphicsDevice.BlendState = BlendState.Opaque; effect.CurrentTechnique.Passes["Ambient"].Apply(); foreach (ModelMeshPart part in mesh.MeshParts) { graphicsDevice.SetVertexBuffer(part.VertexBuffer); graphicsDevice.Indices = part.IndexBuffer; // Texturing graphicsDevice.BlendState = BlendState.AlphaBlend; if (modelTexture != null) { effect.Parameters["Texture"].SetValue( modelTexture ); } graphicsDevice.DrawIndexedPrimitives( PrimitiveType.TriangleList, part.VertexOffset, 0, part.NumVertices, part.StartIndex, part.PrimitiveCount ); // Applying our shader to all the mesh parts effect.Parameters["WVP"].SetValue( world * camera.View * camera.Projection ); effect.Parameters["World"].SetValue(world); effect.Parameters["eyePosition"].SetValue( camera.Position ); graphicsDevice.BlendState = BlendState.Additive; // Drawing lights foreach (DirectionalLight light in DirectionalLights) { effect.Parameters["lightColor"].SetValue(light.Color.ToVector3()); effect.Parameters["lightDirection"].SetValue(light.Direction); // Applying changes and drawing them effect.CurrentTechnique.Passes["Directional"].Apply(); graphicsDevice.DrawIndexedPrimitives( PrimitiveType.TriangleList, part.VertexOffset, 0, part.NumVertices, part.StartIndex, part.PrimitiveCount ); } } I am also applying this when loading the effect: effect.Parameters["lightColor"].SetValue(Color.White.ToVector3()); effect.Parameters["globalAmbient"].SetValue(Color.White.ToVector3()); effect.Parameters["Ke"].SetValue(0.0f); effect.Parameters["Ka"].SetValue(0.01f); effect.Parameters["Kd"].SetValue(1.0f); effect.Parameters["Ks"].SetValue(0.3f); effect.Parameters["specularPower"].SetValue(100); Thank you very much UPDATE: I tried to load an effect for each model when drawing, but it doesn't seem to have changed anything. I suppose it is because XNA detects that the effect has already been loaded before and doesn't want to load a new one. Any idea why?

• Serializing ActiveRecord objects without storing their attributes?

  - by Allan Grant

  I'm working on a problem where I need to store serialized hierarchies of Ruby objects in the database. Many of the objects that will need to be saved are ActiveRecord objects with a lot of attributes. Instead of saving the entire objects and then refreshing their attributes from the DB when I load them (in case they changed, which is likely), it would be easier to just store the references (class and database id) for these objects. Does anyone know if there's already a way to do this in Rails, or if there's an existing gem for it? Wanted to check if something existed before spending a ton of time hacking on it.

• How to invoke an Objective-C Block via the LLVM C++ API?

  - by smokris

  Say, for example, I have an Objective-C compiled Module that contains something like the following: typedef bool (^BoolBlock)(void); BoolBlock returnABlock(void) { return Block_copy(^bool(void){ printf("Block executing.\n"); return YES; }); } ...then, using the LLVM C++ API, I load that Module and create a CallInst to call the returnABlock() function: Function *returnABlockFunction = returnABlockModule->getFunction(std::string("returnABlock")); CallInst *returnABlockCall = CallInst::Create(returnABlockFunction, "returnABlockCall", entryBlock); How can I then invoke the Block returned via the returnABlockCall object?

• Different Providers, different websites, still think I'm logged in on the same website.

  - by Mike

  I have two web applications in the same solution. They both use different membership/profile and role providers. They are named differently. When I run the solution, and visit one website, and login everything is fine. I then go to the other solution and it thinks I am already logged in and the profile provider tries to load profile properties that do not exist. How can I keep them separate, so when I try to log in on one site, it doesn't think I'm still logged in on the other.

• How to keep an Hibernate's Session open until the page is rendered

  - by Neuquino

  I'm having the following problem: I'm using Oracle ADF for the view and controller of my app. With OpenSessionInViewFilter, I intercept the request and open an Hibernate's Session, and it is closed as soon as the bean's method finishes. What I need is to keep the Session opened until the page is rendered, because in my JSP y use the lazy attributes of the object i load from the DB. For example: When I enter index.jspx the IndexBean#main() is executed: public class IndexBean{ private DBObject myDBObject; public String main(){ this.myDBObject = this.myDAO.loadObjectFromDB(); return null; } } in index.jspx I have: ... <af:inputText value="#{myDBObject.lazyAttribute}" /> ... I'd like that the Hibernate's Session keeps open until the af:inputText is processed. Is this possible? How? Thanks in advance

• Flash AS 3 Loader OnComplete Inside a Loop

• Emacs: Define a function which loads the file where the function itself is defined

  - by damd

  I'm refactoring a bit in my Emacs set up and have come to the conclusion that I want to use a different init file than the default one. So basically, in my ~/.emacs file, I have this: (load "/some/directory/init.el") Up until now, that's been working just fine. However, now I want to redefine an old command that I've used for ages, which opens my init file: (defun conf () "Open a buffer with the user init file." (interactive) (find-file user-init-file)) As you can see, this will open ~/.emacs no matter what I do. I want it to open /some/directory/init.el, or wherever the conf command itself is defined. How would I do that?

• Losing NSManaged Objects in my Application

  - by Wayfarer

  I've been doing quite a bit of work on a fun little iPhone app. At one point, I get a bunch of player objects from my Persistant store, and then display them on the screen. I also have the options of adding new player objects (their just custom UIButtons) and removing selected players. However, I believe I'm running into some memory management issues, in that somehow the app is not saving which "players" are being displayed. Example: I have 4 players shown, I select them all and then delete them all. They all disappear. But if I exit and then reopen the application, they all are there again. As though they had never left. So somewhere in my code, they are not "really" getting removed. MagicApp201AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; context = [appDelegate managedObjectContext]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *desc = [NSEntityDescription entityForName:@"Player" inManagedObjectContext:context]; [request setEntity:desc]; NSError *error; NSMutableArray *objects = [[[context executeFetchRequest:request error:&error] mutableCopy] autorelease]; if (objects == nil) { NSLog(@"Shit man, there was an error taking out the single player object when the view did load. ", error); } int j = 0; while (j < [objects count]) { if ([[[objects objectAtIndex:j] valueForKey:@"currentMultiPlayer"] boolValue] == NO) { [objects removeObjectAtIndex:j]; j--; } else { j++; } } [self setPlayers:objects]; //This is a must, it NEEDS to work Objects are all the players playing So in this snippit (in the viewdidLoad method), I grab the players out of the persistant store, and then remove the objects I don't want (those whose boolValue is NO), and the rest are kept. This works, I'm pretty sure. I think the issue is where I remove the players. Here is that code: NSLog(@"Remove players"); /** For each selected player: Unselect them (remove them from SelectedPlayers) Remove the button from the view Remove the button object from the array Remove the player from Players */ NSLog(@"Debugging Removal: %d", [selectedPlayers count]); for (int i=0; i < [selectedPlayers count]; i++) { NSManagedObject *rPlayer = [selectedPlayers objectAtIndex:i]; [rPlayer setValue:[NSNumber numberWithBool:NO] forKey:@"currentMultiPlayer"]; int index = [players indexOfObjectIdenticalTo:rPlayer]; //this is the index we need for (int j = (index + 1); j < [players count]; j++) { UIButton *tempButton = [playerButtons objectAtIndex:j]; tempButton.tag--; } NSError *error; if ([context hasChanges] && ![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } UIButton *aButton = [playerButtons objectAtIndex:index]; [players removeObjectAtIndex:index]; [aButton removeFromSuperview]; [playerButtons removeObjectAtIndex:index]; } [selectedPlayers removeAllObjects]; NSError *error; if ([context hasChanges] && ![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } NSLog(@"About to refresh YES"); [self refreshAllPlayers:YES]; The big part in the second code snippet is I set them to NO for currentMultiPlayer. NO NO NO NO NO, they should NOT come back when the view does load, NEVER ever ever. Not until I say so. No other relevant part of the code sets that to YES. Which makes me think... perhaps they aren't being saved. Perhaps that doesn't save, perhaps those objects aren't being managed anymore, and so they don't get saved in. Is there a lifetime (metaphorically) of NSManaged object? The Players array is the same I set in the "viewDidLoad" method, and SelectedPlayers holds players that are selected, references to NSManagedObjects. Does it have something to do with Removing them from the array? I'm so confused, some insight would be greatly appreciated!!

• OpenExeConfiguration Path Issue

  - by Harry

  I'm trying to load an web.config from a server. Its placed at: \server\folders\web.config when i try this: ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web.config"); it searches for: web.config.config and fails. ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web"); it fails, because there is no folder \server\folders\web\ So i tried several things and it seems as its checking wether the file the path is pointing on exists, and afterwards it appliers a .config and gets the config file. Just for fun i created an web.loaders file, and a web.loaders.config file. with ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web.local"); it loads the \server\folders\web.local.config perfectly, but throws Exceptions without the web.local file. So there a many ways to get this small thing loaded, but isn't there a more nice one than using a temp .web file or something? Any help i highly appreciated, yours Harry

• Babel Django Off By 1 Cent

  - by Dave

  I ran into a problem today while using BabelDjango and thought I would ask if anyone has ran into anything similar. I was using the tags in my templates, {% load babel %} and then {{amount_owed|currencyfmt:"USD"}} which returned the amount_owed minus one-cent. I thought maybe the returned value was 9.949999 which should still be $9.95 but when I returned the raw value it returned "9.95". However when I formatted it using the babel tags the rsult was off by one-cent. My 9.95 returned "$9.94" Anyone have any advice where to look to troubleshoot this problem? Thanks in advance for your help.

• Ruby: Locate class definition at run time?

  - by Thor Thurn

  I'm having an odd probably with rails right now... a class is being defined somewhere, and I can't find it. Grepping for "class ClassName" hasn't managed to locate it, but it's definitely there when I load up the rails console. It's just a vanilla class inheriting from Object with nothing else defined... quite boring. So, what I'd like is a way to figure out where this class constant was originally defined from the rails console.
