问题 I want to call a method before the execution of every and each controller's method. I don't want to go and call the method in every method.

问题 I think I'm beginning to be confused with the job of a controller in MVC. I have a service that exposes five functions: list packages in queue get package delete package accept package deny package My ASP.NET MVC controller depends on this service, and can generally execute a service call on an Action. I'm happy so far. The second part is then building the ViewModel result. If I do this inside of the controller, the controller now has an exploding dependency list -- each action added

问题 I'd like to trigger a remote action for a model using a link. Basically all this link needs to do is trigger a method with one parameter. Here's my code: = link_to 'Move Up', reorder_collection_folder_path(@collection, folder), :reorder => :up, :remote => true This does trigger the Folders#reorder controller action as expected, but the :reorder param is not being passed through. My log says: Started GET "/collections/1/folders/1/reorder" for 127.0.0.1 at 2011-03-01 18:03:31 -0600 Processing

问题 I have an MVC WebAPI 2 project with a Controllers controller. The Method I'm trying to call is POST (Create). I need to access the referring URL that called that method yet, no matter what object I access, the referring URL either doesn't exist in the object or is null. For example, I've added the HTTPContext reference and the following returns null : var thingythingthing = HttpContext.Current.Request.UrlReferrer; The Request object does not have a UrlReferrer property.
