  • Laravel - public layout not needed in every function

    - by fischer
    I have just recently started working with Laravel. Great framework so far! However I have a question. I am using a layout template like this: public $layout = 'layouts.private'; This is set in my Base_Controller: public function __construct(){ //Styles Asset::add('reset', 'css/reset.css'); Asset::add('main', 'css/main.css'); //Scripts Asset::add('jQuery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js'); //Switch layout template according to the users auth credentials. if (Auth::check()) { $this -> layout = 'layouts.private'; } else { $this -> layout = 'layouts.public'; } parent::__construct(); } However I get an error exception now when I try to access functions in my diffrent controllers, which should not call any view, i.e. when a user is going to login: class Login_Controller extends Base_Controller { public $restful = true; public function post_index() { $user = new User(); $credentials = array('username' => Input::get('email'), 'password' => Input::get('password')); if (Auth::attempt($credentials)) { } else { } } } The error I get, is that I do not set the content of the different variables in my public $layout. But since no view is needed in this function, how do I tell Laravel not to include the layout in this function? The best solution that I my self have come a cross (don't know if this is a bad way?) is to unset($this -> layout); from function post_index()... To sum up my question: how do I tell Laravel not to include public $layout in certain functions, where a view is not needed? Thanks in advance, fischer

  • How to : required validator based on user role ASP.Net MVC 3

    - by user70909
    Hi, i have a form where i have the field "Real Cost" i want to customize its appearance and wither it should be validated based on user role. to be more clear is say the client want to show his field in the form or details page and also make it editable for users in Roles "Senior Sales, Manager" but not other roles, so can anyone please guide me of the best way ? should i write custom required validation based on user in role, and if so can you please provide the right implementation of it? some may tell me create custom model for this, but i think it would be hassle plus the Roles will be dynamic so it is not predefined set of roles. i hope i was clear enough

  • How do I hook into the action method for an iPad popover toolbar button?

    - by Elisabeth
    Hi, I am using the split view template to create a simple split view that has, of course, a popover in Portrait mode. I'm using the default code generated by template that adds/removes the toolbar item and sets the popover controller and removes it. These two methods are splitViewController:willShowViewController:... and splitViewController:willHideViewController:... I'm trying to figure out how to make the popover disappear if the user taps on the toolbar button while the popover is displayed. You can make the popover disappear without selecting an item if you tap anywhere outside the popover, but I would also like to make it disappear if the user taps the button again. Where I'm stuck is this: there doesn't seem to be an obvious, easy way to hook into the action for the toolbar button. I can tell, using the debugger, that the action that's being called on the button is showMasterInPopover. And I am new to working with selectors programmatically, I admit. Can I somehow write an action and set it on the toolbar item without overriding the action that's already there? e.g. add an action that calls the one that's there now? Or would I have to write an action that shows/hides the popover myself (behavior that's being done behind the scenes presumably by the split view controller now???). Or am I missing an easy way to add this behavior to this button without changing the existing behavior that's being set up for me? Thank you!

  • Memory leaks with UIWebView and NSURL: already spent several days trying to solve them

    - by Sander de Jong
    I have already found a lot of information about how to solve memory leaks for iPhone Obj C code. The last two leaks keep me puzzled, I'm probably overlooking something. Maybe you can spot it. Instruments reports 2 leaks for the following code (part of a UIViewController subclass): (1) UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, self.view.bounds.size.height - LOWER_VERT_WINDOW_MARGIN)]; (2) webView.scalesPageToFit = YES; (3) webView.dataDetectorTypes = UIDataDetectorTypeNone; (4) (5) NSURL *url = [NSURL fileURLWithPath:self.fullPathFileName isDirectory:NO]; (6) NSMutableURLRequest *urlRequest = [[NSMutableURLRequest alloc] initWithURL:url]; (7) [webView loadRequest:urlRequest]; (8) [urlRequest release], urlRequest = nil; (9) [self.view addSubview:webView]; (10) [webView release], webView = nil; Instruments claims 128 bytes are leaking in line 1, as well as 256 bytes in line 4. No idea if it means line 3 or line 5. Does anybody have a clue what I'm overlooking?

  • Figuring if a link is clicked on a webView - iPhone

    - by Uygar
    Hi, I am using a custom webview to show a tabbar when user touches on the webview. But when I clicked on a link in a webview, tabbar is shown for a little time and then page loads. I am using this custom webview to detect touch: http://github.com/psychs/iphone-samples/blob/b772b963f2acf18d478b41b44555992fcd8d4f31/WebViewTappingHack/Classes/PSWebView.m Can I detect if a link clicked or not? Because a link stands on the webview, webview detects the touch and also it loads the page... I want to prevent it. Thanks in advance.

  • Getting gridview column value as parameter for javascript function

    - by newName
    I have a gridview with certain number of columns and the ID column where I want to get the value from is currently set to visible = false. The other column is a TemplateField column (LinkButton) and as the user clicks on the button it will grab the value from the ID column and pass the value to one of my javascript function. WebForm: <script language=javascript> function openContent(contentID) { window.open('myContentPage.aspx?contentID=' + contentID , 'View Content','left=300,top=300,toolbar=no,scrollbars=yes,width=1000,height=500'); return false; } </script> <asp:GridView ID="gvCourse" runat="server" AutoGenerateColumns="False" OnRowCommand="gvCourse_RowCommand" OnRowDataBound="gvCourse_RowDataBound" BorderStyle="None" GridLines="None"> <RowStyle BorderStyle="None" /> <Columns> <asp:TemplateField> <ItemTemplate> <asp:LinkButton ID="lnkContent" runat="server" CommandName="View" CommandArgument='<%#Eval("contentID") %>' Text='<%#Eval("contentName") %>'> </asp:LinkButton> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="contentID" HeaderText="contentID" ReadOnly="True" SortExpression="contentID" Visible="False" /> <asp:BoundField DataField="ContentName" HeaderText="ContentName" ReadOnly="True" SortExpression="ContentName" Visible="False" /> </Columns> <AlternatingRowStyle BorderStyle="None" /> Code behind: protected void gvCourse_RowCommand(object sender, GridViewCommandEventArgs e) { if (e.CommandName == "View") { intID = Convert.ToInt32(e.CommandArgument); } } protected void gvCourse_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { ((LinkButton)e.Row.FindControl("lnkContent")).Attributes.Add("onclick", "return openContent('" + intID + "');"); } } right not i'm trying to get the intID based on user selected item so when the user clicks on the linkbutton it will open a popup window using javascript and the ID will be used as querystring.

  • How do I check to see if my subview is being touched?

    - by Amy
    I went through this tutorial about how to animate sprites: http://icodeblog.com/2009/07/24/iphone-programming-tutorial-animating-a-game-sprite/ I've been attempting to expand on the tutorial by trying to make Ryu animate only when he is touched. However, the touch is not even being registered and I believe it has something to do with it being a subview. Here is my code: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [touches anyObject]; if([touch view] == ryuView){ NSLog(@"Touch"); } else { NSLog(@"No touch"); } } -(void) ryuAnims{ NSArray *imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"1.png"], [UIImage imageNamed:@"2.png"], [UIImage imageNamed:@"3.png"], [UIImage imageNamed:@"4.png"], [UIImage imageNamed:@"5.png"], [UIImage imageNamed:@"6.png"], [UIImage imageNamed:@"7.png"], [UIImage imageNamed:@"8.png"], [UIImage imageNamed:@"9.png"], [UIImage imageNamed:@"10.png"], [UIImage imageNamed:@"11.png"], [UIImage imageNamed:@"12.png"], nil]; ryuView.animationImages = imageArray; ryuView.animationDuration = 1.1; [ryuView startAnimating]; } -(void)viewDidLoad { [super viewDidLoad]; UIImageView *image = [[UIImageView alloc] initWithFrame: CGRectMake(100, 125, 150, 130)]; ryuView = image; ryuView.image = [UIImage imageNamed:@"1.png"]; ryuView.contentMode = UIViewContentModeBottomLeft; [self.view addSubview:ryuView]; [image release]; } This code compiles fine, however, when touching or clicking on ryu, nothing happens. I've also tried if([touch view] == ryuView.image) but that gives me this error: "Comparison of distinct Objective-C type 'struct UIImage *' and 'struct UIView *' lacks a cast." What am I doing wrong?

  • iPhone – Best method to import/drawing UI graphic elements? CGContextDrawPDFPage?

    - by Ross
    Hello, What is the best way to use the custom UI graphics on the iPhone? I've come across CGContextDrawPDFPage and Panic's Shrinkit. Should I be using storing my vector ui graphics as PDF's and loading them using CGContextDrawPDFPage to draw them. I did previously asked what way Apple store their UI graphics and was answered crushed png. The options as I see it, but I would really want to know what technique other people use. This question is for vector graphics only. Looking for what is standard / most effective / most efficient. PNG (bitmapped image) Custom UIView drawing code (generated from Opacity) PDF (I've not used this method, is it with CGContextDrawPDFPage?) Many thanks Ross

  • How do I specify a crossdomain policy file to allow Flash to grab a bitmap from an RTMP (Wowza) vide

    - by Ken Smith
    I'm trying to get a bitmap/snapshot of a Wowza video stream playing on my client, like so: var bitmapData:BitmapData = new BitmapData(view.videoPlayerComponent.width, view.videoPlayerComponent.height); bitmapData.draw(view.videoPlayerComponent); When I do this, I get this error message: SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: http://localhost:51150/Resources/WRemoteWebCam.swf cannot access rtmp://localhost/videochat/smithkl42._default/. No policy files granted access. I presume the error comes from not being able to locate the appropriate crossdomain.xml file. I'm not quite sure where it's looking for it, and a wireshark sniff was inconclusive, so I've tried placing one in each of the following places: http://localhost/crossdomain.xml http://localhost:1935/crossdomain.xml http://localhost:51150/crossdomain.xml I can retrieve the file successfully from each of those three locations. (I'm pretty sure that the last one wouldn't have any effect, since it's just the location of the web site which hosts the page that hosts the .swf file, but on the off chance...) These are the contents of the file that it's grabbing in each instance: <cross-domain-policy> <allow-access-from domain="*" to-ports="*" /> </cross-domain-policy> And it's still throwing that same error message. I've also followed the instructions on the Wowza forums, to turn on StreamVideoSampleAccess in the [install]\conf[appname]\Application.xml, with no joy: <Client> <IdleFrequency>-1</IdleFrequency> <Access> <StreamReadAccess>*</StreamReadAccess> <StreamWriteAccess>*</StreamWriteAccess> <StreamAudioSampleAccess>*</StreamAudioSampleAccess> <StreamVideoSampleAccess>*</StreamVideoSampleAccess> <SharedObjectReadAccess>*</SharedObjectReadAccess> <SharedObjectWriteAccess>*</SharedObjectWriteAccess> </Access> </Client> Any thoughts?

  • Sharepoint and Cross-Site Lookup

    - by Mina Samy
    Hi all I have this scenario I want to build two sharepoint 2007 sites. One for customers info and the other for products and customers orders. Now the problem is that in the second site I need to reference the customers info from the first site but unfortunately sharepoint doesnot provide out of the box cross-site lookup. I did some search and found custom cross-site fields and used one but when I upgraded the site to sharepoint 2010 this custom field was not compatible and the upgrade wizard said it could not be upgraded. so what is the solution for this ? is it to merge the two sites so that I can use the standard lookup feature or is there any workaround for this ? please if any body has faced such a scenario, share the solution with me ? thanks

  • Why does Facebook iOS dialog for feed publish disappear after login?

    - by Mason G. Zhwiti
    I'm trying to use the Facebook iOS "feed" dialog call to allow my app's user to share something on their Facebook wall. When the facebook app is not installed, it attempts to let them authenticate within the app (presumably using a web view). The issue is that this dialog just disappears once they authenticate. I was expecting the web view to return to the "feed" sharing view. How do I detect that they authenticated so that I can re-open the feed dialog? I've added fbDidLogin to my app delegate, but it's not being called. (I wasn't sure if this would normally be called or not, but I read several people recommending this.) SBJSON *jsonWriter = [SBJSON new]; // The action links to be shown with the post in the feed NSArray* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys: @"More Videos",@"name",@"http://www.example.com/",@"link", nil], nil]; NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks]; NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: @"Test Caption", @"caption", @"Test Description", @"description", @"https://s3.amazonaws.com/example/images/test.png", @"source", self.video.blogLink, @"link", @"01234567890123", @"app_id", actionLinksStr, @"actions", nil]; [delegate facebook].sessionDelegate = delegate; [[delegate facebook] dialog:@"feed" andParams:params andDelegate:self];

  • using jquery draggable can you create a helper based on the dragged item?

    - by user169867
    I wish to create a custom helper based on the element being dragged. I'm dragging documents and I'd like the document's number to be part of the custom helper. I know how to create a helper during init like this: helper: function() { return $("<div class='fax16'></div>"); } But what I really want to do is maybe in response to the start event get access to the element being dragged and use some of its properties to set the helper. Something like: start: function(event, ui) { var docID = //somehow access the dragged element ui.helper = $("<div class='save16'>" + docID + "</div>"); //Set drag Helper } Can this be done?

  • ASP.NET Timer Event

    protected void SubmitButtonClicked(object sender, EventArgs e) { System.Timers.Timer timer = new System.Timers.Timer(); --- --- //line 1 get_datasource(); String message = "submitted."; ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "popupAlert", "popupAlert(' " + message + " ');", true); timer.Interval = 30000; timer.Elapsed += new ElapsedEventHandler(timer_tick); // Only raise the event the first time Interval elapses. timer.AutoReset = false; timer.Enabled = true; } } protected void timer_tick(object sender, EventArgs e) { //line 2 get_datasource(); GridView2.DataBind(); } The problem is with the data in the grid view that is being displayed... since when get_datasource which is after line 1 is called the updated data is displayed in the grid view since it is a postback event but when the timer event handler is calling the timer_tick event the get_datasource function is called but after that the updated data is not visible in the grid view. It is nnot getting updated since the timer_tick is not a post back event

  • Design question for WinForms (C#) app, using Entity Framework

    - by cdotlister
    I am planning on writing a small home budget application for myself, as a learning excercise. I have built my database (SQL Server), and written a small console application to interact with it, and test out scenarios on my database. Once I am happy, my next step would be to start building the application - but I am already wondering what the best/standard design would be. I am palnning on using Entity Framework for handling my database entities... then linq to sql/objects for getting the data, all running under a WinForms (for now) application. My plan (I've never used EF... and most of my development background is Web apps) is to have my database... with Entity Framework in it's own project.. which has the connection to the database. This project would expose methods such as 'GetAccount()', 'GetAccount(int accountId)' etc. I'd then have a service project that references my EF project. And on top of that, my GUI project, which makes the calls to my service project. But I am stuck. Lets say I have a screen that displays a list of Account types (Debit, Credit, Loan...). Once I have selected one, the next drop down shows a list of accounts I have that suite that account type. So, my OnChange event on my DropDown on the account type control will make a call to the serviceLayer project, 'GetAccountTypes()', and I would expect back a List< of Account Types. However, the AccountType object ... what is that? That can't be the AccountType object from my EF project, as my GUI project doesn't have reference to it. Would I have to have some sort of Shared Library, shared between my GUI and my Service project, with a custom built AccountType object? The GUI can then expect back a list of these. So my service layer would have a method: public List<AccountType> GetAccountTypes() That would then make a call to a custom method in my EF project, which would probably be the same as the above method, except, it returns an list of EF.Data.AccountType (The Entity Framework generated Account Type object). The method would then have the linq code to get the data as I want it. Then my service layer will get that object, and transform it unto my custom AccountType object, and return it to the GUI. Does that sound at all like a good plan?

  • WPF TabBarControl Setting Focus to element when tab changes

    I have a TabControl that is bound to a view model <TabControl ItemsSource="{Binding Path=ViewModelCollection}" > <TabControl.ItemContainerStyle> <Style TargetType="TabItem" BasedOn="{StaticResource {x:Type TabItem}}"> <Setter Property="Header" Value="{Binding Title}" /> <Setter Property="Content" Value="{Binding}" /> </Style> </TabControl.ItemContainerStyle> </TabControl> Each Tab simply contains a View Model Item. I use a data template to display this. <!-- View Model Template --> <DataTemplate DataType="{x:Type local:ViewModelItem}"> <DockPanel> <TextBox Text="I want this to have the focus"/> </DockPanel> </DataTemplate> When the current tab is changed i want the focus to be on the textbox (this is a simple example, in my production code i have a datagrid) in the data template. how do i accomplish this?

  • Django Admin interface with pickled set

    - by Rosarch
    I have a model that has a pickled set of strings. (It has to be pickled, because Django has no built in set field, right?) class Foo(models.Model): __bar = models.TextField(default=lambda: cPickle.dumps(set()), primary_key=True) def get_bar(self): return cPickle.loads(str(self.__bar)) def set_bar(self, values): self.__bar = cPickle.dumps(values) bar = property(get_bar, set_bar) I would like the set to be editable in the admin interface. Obviously the user won't be working with the pickled string directly. Also, the interface would need a widget for adding/removing strings from a set. What is the best way to go about doing this? I'm not super familiar with Django's admin system. Do I need to build a custom admin widget or something? Update: If I do need a custom widget, this looks helpful: http://www.fictitiousnonsense.com/archives/22

  • Survey on logging classes / frameworks / writers

    - by ts
    I am curious what writers (handlers, loggers) are you using. Text file and db its quite obvious, but what are other possibilities ? Firephp maybe (as in Zend_Log), mail, jabber, url ? Is anyone using syslog() or error_log() ? Are you using streams (especially custom ones) ? Are you using custom error levels or you limit yourself to predefined values? Are you logging common php errors / warning / notices? And last question - is there anything new in the town, worth consideration, apart of Zend_Log ? Or are you using your homebrew class?

  • How does one paint the entire row's background in a QStyledItemDelegate ?

    - by Casey Link
    I have a QTableView which I am setting a custom QStyledItemDelegate on. In addition to the custom item painting, I want to style the row's background color for the selection/hovered states. The look I am going for is something like this KGet screenshot: Here is my code: void MyDelegate::paint( QPainter* painter, const QStyleOptionViewItem& opt, const QModelIndex& index ) const { QBrush backBrush; QColor foreColor; bool hover = false; if ( opt.state & QStyle::State_MouseOver ) { backBrush = opt.palette.color( QPalette::Highlight ).light( 115 ); foreColor = opt.palette.color( QPalette::HighlightedText ); hover = true; } QStyleOptionViewItemV4 option(opt); initStyleOption(&option, index); painter->save(); const QStyle *style = option.widget ? option.widget->style() : QApplication::style(); const QWidget* widget = option.widget; if( hover ) { option.backgroundBrush = backBrush; } painter->save(); style->drawPrimitive(QStyle::PE_PanelItemViewItem, &option, painter, widget); painter->restore(); switch( index.column() ) { case 0: // we want default behavior style->drawControl(QStyle::CE_ItemViewItem, &option, painter, widget); break; case 1: // some custom drawText break; case 2: // draw a QStyleOptionProgressBar break; } painter->restore(); } The result is that each individual cell receives the mousedover background only when the mouse is over it, and not the entire row. It is hard to describe so here is a screenshot: In that picture the mouse was over the left most cell, hence the highlighted background.. but I want the background to be drawn over the entire row. How can I achieve this? Edit: With some more thought I've realized that the QStyle::State_MouseOver state is only being passed for actual cell which the mouse is over, and when the paint method is called for the other cells in the row QStyle::State_MouseOver is not set. So the question becomes is there a QStyle::State_MouseOver_Row state (answer: no), so how do I go about achieving that?

  • UIButton not firing selector if I draw it using CALayer

    - by Horatiu Paraschiv
    Hi everybody I create this button like this: _myButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; DLBadgeLayerDelegate *layerDelegate = [[DLBadgeLayerDelegate alloc] init]; _myButton.frame = CGRectMake(0.0 , 0.0, 100.0, 100.0); [_myButton addTarget:self action:@selector(myButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; _myButton.layer.backgroundColor = [[UIColor redColor] CGColor]; _myButton.center = CGPointMake(10.0, 10.0); [self addSubview:_myButton]; [_myButton release]; The button appears on the screen but if I tap on it nothing happens. If I just create a Rounded rect button instead with no custom drawing on its layer or if I just leave the layer line of code out all works well. Do you have any Idea why do I get this behaviour as I would like to do some custom drawing in the button's layer?

  • Visual Studio Package for 2005/2008/2010 ??

    - by asp2go
    We are looking to turn an internal tool we have developed into a Visual Studio Package that we would sell to other developers. The tool will impact the custom editor and/or custom languages. Visual Studio 2010 has redesigned the API's heavily to simplify much of the work involved for these types of integration but the key question we have is: What is the typical adoption pace of new Visual Studio versions? Is there any information out there on adoption rates based on history? How many shops are still using 2005? This will help us to consider whether to target just 2010 using the new APIs or whether trying to go back and support 2008 (maybe 2005) and testing it forward.

  • How to start develop for chinese mobile phones based on nucleus RTOS? (MTK)

    - by juckobee
    I've noticed that chinese mobile phones became very popular, perhaps because of their very reasonable price and many modern features (touch screens, advanced multimedia, double sim cards etc). I'm wondering if there's any way to develop custom solutions for this handsets as independent developer? How to obtain a toolkit and documentation? I've found some resources, but mainly inconsistent tech notes, often in chinese only. For now I know, that majority of chinese handsets are based on chips from MediaTek (MTK), with operating system based on Nucleus RTOS and MMI (plutoMMI?) framework. Unfortunately, there is no Java RE avaiable (ok, there are some handsets with Java, however, Java isn't something I'm looking for) Is there any SDK, documentation, emulators/simulators, how-tos, etc avaiable? How to develop, deploy and test custom application for MTK mobile?

  • Assign binding path at runtime in WPF DataTemplate

    - by Abiel
    I am writing a WPF program in C# in which I have a ListView for which the columns will be populated at runtime. I would like to use a custom DataTemplate for the GridViewColumn objects in the ListView. In the examples I have seen where the number of columns is fixed in advance, a custom DataTemplate is often created using something like the XAML below. <DataTemplate x:Key="someKey"> <TextBlock Text="{Binding Path=FirstName}" /> </DataTemplate> This DataTemplate could also later be assigned to GridViewColumn.CellTemplate in the code-behind by calling FindResource("someKey"). However, this alone is of no use to me, because in this example the Path element is fixed to FirstName. Really I need something where I can set the Path in code. It is my impression that something along these lines may be possible if XamlReader is used, but I'm not sure how in practice I would do this. Any solutions are greatly appreciated.

  • Visual Studio 2010 Extensibility, MPF and language services

    - by MainMa
    Hi, I am trying to extend Visual Studio 2010 RC to be able to use a custom programming language. The first two things I've tried to do is a syntax highlight/Intellisense feature (easily done, thanks to "Ook!" sample from PDC09) and a possibility to create new project templates (i.e. be able to open *.myproj files). For this second task, I can't find any easy tutorials or samples. Most samples are for Visual Studio 2008 (as for IronPython integration) or even VS2003. The few samples available for VS2010 do not work (including MPFProj) or do not compile, and are too hard to understand. Is there any easy-to-understand sample, either using MPFProj or a standalone solution, showing how to integrate templates for a custom language inside Visual Studio 2010?

  • Asp.Net MVC Tutorial Unit Tests

    - by Nicholas
    I am working through Steve Sanderson's book Pro ASP.NET MVC Framework and I having some issues with two unit tests which produce errors. In the example below it tests the CheckOut ViewResult: [AcceptVerbs(HttpVerbs.Post)] public ViewResult CheckOut(Cart cart, FormCollection form) { // Empty carts can't be checked out if (cart.Lines.Count == 0) { ModelState.AddModelError("Cart", "Sorry, your cart is empty!"); return View(); } // Invoke model binding manually if (TryUpdateModel(cart.ShippingDetails, form.ToValueProvider())) { orderSubmitter.SubmitOrder(cart); cart.Clear(); return View("Completed"); } else // Something was invalid return View(); } with the following unit test [Test] public void Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error() { // Arrange CartController controller = new CartController(null, null); Cart cart = new Cart(); cart.AddItem(new Product(), 1); // Act var result = controller.CheckOut(cart, new FormCollection { { "Name", "" } }); // Assert Assert.IsEmpty(result.ViewName); Assert.IsFalse(result.ViewData.ModelState.IsValid); } I have resolved any issues surrounding 'TryUpdateModel' by upgrading to ASP.NET MVC 2 (Release Candidate 2) and the website runs as expected. The associated error messages are: *Tests.CartControllerTests.Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error: System.ArgumentNullException : Value cannot be null.

  • Unit Testing - Validation of ViewModel ASP.NET MVC 2

    - by dean nolan
    I am currently unit testing a service that adds users to a repository. I am using dependency injection to test using a fake repository. The repository has a method CreateUser(User user) which just adds it to the database or in this case a List of Users. The logic for the creation is in the UserServices class. The application has a form for creating a user that requires some properties such as name and address. This is an MVC 2 app and I will be using the new validation using data annotations. This makes me wonder about a few things: 1) Should I annotate a POCO object that will map to the database? Or should I create a specific View Model that has these annotations and pass this data to the UserServices class? 2)Should the UserServicesClass also check this data? Would I best be constructing a Usr out of the ViewModel and passing this into the Service as a parameter? 3) The actual unit testing would depend on 2), I either populate a User object and pass that in, or I pass a large list of strings to the method CreateUser. Writing this out I get a basic idea that I should probably annotate the view model only, pass in a user (constructed by the view model if the data is valid) and also just construct the user in the unit test also. Is this the best way to go?
