Display a view from another controller in ASP.NET MVC

由 大憨熊 提交于 2019-11-27 05:54:55
Is it possible to display a view from another controller? Say for example I have a CategoriesController and a Category/NotFound.aspx view. While in the CategoriesController , I can easly return View("NotFound") . Now say I have a ProductsController and an action and view to add a product. However, this action requires that we have a Category to add the Product to. For example, Products/Add/?catid=10 . If I am not able to find the Category based on catid , I want to show the NotFound view from the Categories controller instead of creating a CategoryNotFound view under the Products controller.

问题 If I wanted to make a currentUser() function for some oauth stuff I am doing where I can use it in a view or in a controller (think rails, where you do helper_method: current_user in the application controller). Everything I read states to create a helpers folder and add the function there and then that way you can do Helpers::functionName Is this the right way to do this? Whats the "laravel way" of creating helper functions that can be used in blade templates and controllers? 回答1: Create a

问题 Is it possible to get all controllers available to a ControllerFactory? What I want to do is get a list of all controller types in application, but in a consistent way. So that all controllers I get are the same ones default request resolution is using. (The actual task is to find all action methods that have a given attribute). 回答1: You can use reflection to enumerate all classes in an assembly, and filter only classes inherit from Controller class. The best reference is asp.net mvc source

问题 Reading Guru-Gu's blog post about ASP.NET MVC3 hitting RC, he says:- Session-less Controller Support You can now indicate whether you want a Controller class to use session-state – and if so whether you want it to be read/write or readonly.read/write or readonly.

问题 Is possible to connect two FXML (JavaFX) files to one controller? I can't do this with changing "fx:controller" in each FXML file... Any ideas? 回答1: Yes, you can do this. Although, it can be done, I do not recommend this approach . Don't place a fx:controller attribute in either FXML. Create a new controller and set the same controller into separate FXMLLoader instances. CustomerDialogController dialogController = new CustomerDialogController(param1, param2); FXMLLoader summaryloader = new

Angularjs, passing scope between routes

由 試著忘記壹切 提交于 2019-11-26 14:56:51
I have a situation with a form that stretches over several pages (might not be ideal, but that is how it is). I'd like to have one scope for the entire form that gets filled in as you go along, so that if the user goes back and forth between steps it's easy to remember the state. So I need to do, in very-pseudo-code: Set $scope.val = <Some dynamic data> Click a link and be routed to a new template (probably with the same controller). $scope.val should still be the same value as it was on the last page. Is somehow persisting data for the scope the right way to go about this, or is there some
