    Hi, I am new to asp.net mvc platform. I'm developing with razor template engine in mvc 3.

  • Using Django.test.client to check template vars

    - by scott
    I've got a view that I'm trying to test with the Client object. Can I get to the variables I injected into the render_to_response of my view? Example View: def myView(request): if request.method == "POST": # do the search return render_to_response('search.html',{'results':results},context_instance=RequestContext(request)) else: return render_to_response('search.html',context_instance=RequestContext(request) Test: c = Client() response = c.post('/school/search/', {'keyword':'beagles'}) # how do I get to the 'results' variable??

  • UIButton setBackgroundImage consumes doesn't release memory?

    - by just_another_coder
    My UIButton has it's background image set like this: [myImageButton setBackgroundImage:[UIImage imageNamed:myImageName] forState:UIControlStateNormal]; myImageButton is a retained property of the class, and is setup with IB. No where else is it accessed in the app. myImageName is simply an NSString with a filename like @"myImage_number_1.png" I am loading large images, 1024 x 1024 in size. When the view is shown, it changes the image with the above statement, then available memory decreases. After I see the view about 7-9 different times, the app crashes with a memory warning. I thought the method would free up the loaded image. The view itself is only instantiated and allocated one time, so it's not in the retain/release cycle if the view controller. Is there something about this setBackgroundImage I don't know that causes it to not release memory?

  • How do IOS know which viewController is being viewed and hence need viewWillAppear to be called

    - by Jim Thio
    How does iOs know? Does each view has a pointer to it's controller? What happened? When we pop a viewController from navigation, does the navigationController arrange which view should be called? For example: If I added: [[BNUtilitiesQuick window] addSubview:[BNUtilitiesQuick searchController].view]; viewWillAppear will be called. However, window doesn't know the viewController. I am passing the view outlet of the controller not the controller. How can iOs 5 knows that it has to call [[BNUtilitiesQuick searchController] viewWillAppear:YES]

  • Is there a way to get direct_to_template to pass RequestContext in django?

    - by BigJason
    I have found myself writing the same view over and over. It is basically this: def home_index(request): return render_to_response('home/index.html', RequestContext(request)) To keep with the dry principal, I would like to utilize a generic view. I have seen direct_to_template, but it passes an empty context. So how can I use a generic view and still get the power of RequestContext?

  • Clear button at uisearchbar not working at all

    - by kevin.ng
    I created a search bar programmatically and added to my view using the codes below: - (void)viewDidLoad { searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xPositionForSearchBar, yPositionForSearchBar, widthForSearchBar, heightForSearchBar)]; UIView *bg = [[searchBar subviews] objectAtIndex:0]; searchBar.delegate = self; searchBar.placeholder = @"Search record"; for(UIView *view in searchBar.subviews){ if([view isKindOfClass:[UITextField class]]){ UITextField *tf = (UITextField *)view; tf.delegate = self; break; } } [bg removeFromSuperview]; [self.view addSubview: searchBar]; } The code is implemented with UISearchBarDelegate and UITextFieldDelegate. I have tried using - (void)searchBarCancelButtonClicked:(UISearchBar *)aSearchBar { NSLog(@"cancel clicked"); searchBar.text = @""; [aSearchBar resignFirstResponder]; } - (BOOL)textFieldShouldClear:(UITextField *)textField { NSLog(@"clear"); [self performSelector:@selector(searchBarCancelButtonClicked:) withObject:searchBar afterDelay: 0.1]; return YES; } and yet, the text inside the searchBar is not cleared at all when i click on the "clear button" - a circle with a "X" inside. The clear button works when I implemented it in IB. Wonder why? Kindly advice, many thanks.

  • Dealloc'd Predicate crashing iPhone App!

    - by DVG
    To preface, this is a follow up to an inquiry made a few days ago: http://stackoverflow.com/questions/2981803/iphone-app-crashes-when-merging-managed-object-contexts Short Version: EXC_BAD_ACCESS is crashing my app, and zombie-mode revealed the culprit to be my predicate embedded within the fetch request embedded in my Fetched Results Controller. How does an object within an object get released without an explicit command to do so? Long Version: Application Structure Platforms View Controller - Games View Controller (Predicated upon platform selection) - Add Game View Controller When a row gets clicked on the Platforms view, it sets an instance variable in Games View for that platform, then the Games Fetched Results Controller builds a fetch request in the normal way: - (NSFetchedResultsController *)fetchedResultsController{ if (fetchedResultsController != nil) { return fetchedResultsController; } //build the fetch request for Games NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Game" inManagedObjectContext:context]; [request setEntity:entity]; //predicate NSPredicate *predicate = [NSPredicate predicateWithFormat:@"platform == %@", selectedPlatform]; [request setPredicate:predicate]; //sort based on name NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; //fetch and build fetched results controller NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:context sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [sortDescriptor release]; [sortDescriptors release]; [predicate release]; [request release]; [aFetchedResultsController release]; return fetchedResultsController; } At the end of this method, the fetchedResultsController's _fetch_request - _predicate member is set to an NSComparisonPredicate object. All is well in the world. By the time - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section gets called, the _predicate is now a Zombie, which will eventually crash the application when the table attempts to update itself. I'm more or less flummoxed. I'm not releasing the fetched results controller or any of it's parts, and the only part getting dealloc'd is the predicate. Any ideas?

  • Navigating between 2 ViewControllers

    - by Kobe.o4
    Im using Navigation Controller for my ViewControllers,I set my importantViewController as something like this to be its RootView: UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController: vc]; [self presentModalViewController: navControl animated: YES]; Then, I pushView anotherView the FrontViewController like this: [self.navigationController pushViewController:vc animated:YES]; After a button is pressed in FrontViewController another view will be pushed ViewA but it is connected with another ViewController ViewB the same way as this AGAIN: [self.navigationController pushViewController:vc animated:YES]; (Which I think Im doing wrong when dismissing either of them with [self.navigationController popViewControllerAnimated:YES];) This is an illustration: My problem is, I need to navigate between View A and View B then when I dismiss either of them it will got back to FrontViewController. Like a child of a child View. Thanks.

  • Using SQL Server Views with NHibernate

    - by colinramsay
    I have a site that sells cars. On the frontend, I want to only show cars that are published, and on the backend I want to show all cars. Whether a car is published or not depends on a number of factors, so I wanted to create a view to simplify this. My question is, can I reduce duplication by dynamically telling NHibernate to sometimes use the "PublishedCar" view and something use the "AllCar" view when querying/fetching Car entities?

  • How do you preserve the viewstate while using strongly typed views in asp MVC 2?

    - by Mark Kadlec
    I have an ActionResult returning from a strongly typed view where I manually validate some conditions, pass in an error message, but would like to preserve the users responses. Since my View is strongly typed, I am calling it like this: return View("PrincipalInvestigatorForm", new SmartFormViewModel(sections, questions)); My problem though, is that the error message is displayed but all the users data is wiped. How do I preserve the "ViewState" in MVC? Is there an easy way?

  • Visual Studio 2010 deploys views too late in deploy process

    - by Markus
    I have a database project in my VS2010 solution. I recently changed a view and and changed a number of functions to use this view instead of going directly against a table. But now when I deploy I get errors on most of these functions because the column asked for does not exists in the view yet. The update of the view happends later than the update of UDF's. Is there any way to change this behaviour? Wouldn't the best thing be if the deploy script updated in this order: tables, views, SP and UDF. It seems like tables is updated first, but the views are just thrown in somewhere in the middle of the deploy script.

  • Painting on GtkScrolledWindow or GtkEventBox

    - by ptomato
    Using GTK, I'm trying to overlay a "More" prompt (but it could just as well be any drawing object) in the corner of a GtkTextView contained within a GtkScrolledWindow. I draw the prompt in the handler for the expose signal of the text view. It works, but when I scroll the window I get artifacts: the prompt is moved along with the contents of the text view and not erased. In order to get rid of the artifacts I trigger a redraw after each scroll. This mostly works, but you can still see the prompt jumping up and down when you scroll quickly. Is there any way to prevent this? It would be nice if the prompt just "floated" on top of the text view. I tried enclosing the scrolled window in a GtkEventBox and painting the prompt on top of that, but that didn't work either; the scrollbars and text view always paint over the prompt, even when you set the event box's window to go in front of its children's windows. UPDATE If I connect the GtkEventBox's expose callback with g_signal_connect_after(), then it is called after the expose callbacks of the GtkScrolledWindow and GtkTextView. The text view still draws over the event box though. I think this is because the scrolling happens asynchronously. Anybody got any idea how I can prevent my drawing from being overwritten?

  • Layout: how to make image to change its width and height proportionally?

    - by Exterminator13
    I have such layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_centerVertical="true" android:layout_toLeftOf="@+id/my_image" android:ellipsize="end" android:singleLine="true" android:text="Some text" android:textAppearance="?android:attr/textAppearanceMedium" /> <ImageView android:id="@+id/my_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@+id/title" android:layout_alignBottom="@+id/title" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:adjustViewBounds="true" android:src="@drawable/my_bitmap_image" /> This layout does almost what I need: it makes image view height the same as text view. The image graphic contents stretched also keeping aspect ratio. But, the width of the image view does not change! As a result, I have a wide gap between text and the image view! As a temporal solution, I override View#onLayout. The question: how to change image width in xml layout? UPDATE: This is a final layout I need (text + a few images). Look at the first image: its width should be exactly the same as scaled image in it with no paddings and margins:

  • ASP.Net MVC - Models and User Controls

    - by cdotlister
    Hi guys, I have a View with a Master Page. The user control makes use of a Model: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<BudgieMoneySite.Models.SiteUserLoginModel>" %> This user control is shown on all screens (Part of the Master Page). If the user is logged in, it shows a certain text, and if the user isn't logged in, it offers a login box. That is working OK. Now, I am adding my first functional screen. So I created a new view... and, well, i generated the basic view code for me when I selected the controller method, and said 'Create View'. My Controller has this code: public ActionResult Transactions() { List<AccountTransactionDetails> trans = GetTransactions(); return View(trans); } private List<AccountTransactionDetails> GetTransactions() { List<AccountTransactionDto> trans = Services.TransactionServices.GetTransactions(); List<AccountTransactionDetails> reply = new List<AccountTransactionDetails>(); foreach(var t in trans) { AccountTransactionDetails a = new AccountTransactionDetails(); foreach (var line in a.Transactions) { AccountTransactionLine l = new AccountTransactionLine(); l.Amount = line.Amount; l.SubCategory = line.SubCategory; l.SubCategoryId = line.SubCategoryId; a.Transactions.Add(l); } reply.Add(a); } return reply; } So, my view was generated with this: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<System.Collections.Generic.List<BudgieMoneySite.Models.AccountTransactionDetails>>" %> Found <%=Model.Count() % Transactions. All I want to show for now is the number of records I will be displaying. When I run it, I get an error: "The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[BudgieMoneySite.Models.AccountTransactionDetails]', but this dictionary requires a model item of type 'BudgieMoneySite.Models.SiteUserLoginModel'." It looks like the user control is being rendered first, and as the Model from the controller is my List<, it's breaking! What am I doing wrong?

  • Show a SplashScreenScene before to GameScene?

    - by lisovaccaro
    I want to add a splash screen to my game. I created a SplashScene.sks and a SplashScene.swift file. I'm trying to load my SplashScene before GameScene but I cannot manage to do it. How should I do this? This is what I'm trying now: class GameViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let skView = self.view as SKView skView.ignoresSiblingOrder = true /* Set the scale mode to scale to fit the window */ var scene = SplashScreenScene() // Present SplashScreenScene first scene.scaleMode = .AspectFill skView.presentScene(scene) } Then on my SplashScreenScene: class SplashScreenScene: SKScene { override func didMoveToView(view: SKView) { self.size = view.bounds.size self.anchorPoint = CGPointMake(0.5, 0.5) var background = SKSpriteNode(imageNamed:"LaunchImage") self.addChild(background) // Start timer to load next scene NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: Selector("changeScene"), userInfo: nil, repeats: false) } func changeScene() { let scene = GameScene() view.presentScene(scene) } } This is very close to the solution, however for some reason when I do this my game becomes laggy (if I present GameScene directly the game runs fine).

  • How can I take zooming into account when a user touches a UIScrollView?

    - by Bill
    I have a UIImageView inside of a UIScrollView. The parent scroll view allows zooming and panning. When the user taps a point in the scroll view, I want to find the location in the raw image inside the UIImageView - i.e. I want the point after including any zooming and panning the user has done in the scroll view. Right now, I have a UIScrollView subclass called ForwardingScrollView that handles touch events and attempts to convert them into locations in the coordinate system of the child image view. I tried adding contentOffset to these points, tried multiplying them by zoomScale, and even tried doing both. I also tried calling [touch locationInView: self] and [touch locationInView: parent], but none of these methods correctly return the point that I clicked in the underlying image. What's the best way to do this? Thanks in advance.

  • Is it possible to change the default InputView in MonoTouch?

    - by Pwninstein
    I would like to display a different view than the standard keyboard (a picker control, or a date picker, for example) when a text field becomes first responder (i.e. gets focus). This would be really nice, because currently I'm pushing a custom view which contains my picker control onto the navigation stack where the user chooses an option, and then hits an OK or Cancel button. According to the documentation for UITextField.InputView: Assigning a custom view to this property causes that view to be presented instead. But, It's read only!!! Is there a workaround for this? Do I need to implement a custom UITextField control and somehow override the InputView property? Do I need to call some kind of native function? I'd really love not to have to do either of those things... but if I have to, so be it. Thanks in advance!
