C# - Run Both Authorize Filter And Action Filter On Unauthenticated MVC Request
Mar 17, 2010I have decorated my base controller with a couple of action filters. They work fine.
One of those filters sets up the request - does things like set the culture based on the domain, etc.
I also have a handful of actions that require authorization using the Authorize attribute.
My problem is that when an user attempts to request a page they are not authorized to access, the authorization filter kicks in and redirects them to a page telling them that they cannot vie the page.
The issue is that the action filters never run so the culture and other request data is never set. This effectively causes language to be wrong in the view and other data to be missing.
I know that authorization filters run first but my question is this: How can I design this such that I can ensure that certain methods are always run before the view is returned, regardless of the authorization.

MVC :: Add A Default Value To Action Filter?
Dec 10, 2010I just learned about actionfilters yesterday and thought it would be great if i could put my meta data into a action filter and change the page title, page description etc from 1 location based on a value from the controller.
I've getting so far, but cannot seem to work out how to add the default value to the controller and pass that value to my actionfilter.

MVC :: Edit The Content Of A View From An Action Filter?
Jan 6, 2011Is it possible to edit the content of a view from a action filter.
What I am working on is a Resourcemanager that I can use to manage
my style sheets, js and other resources. I want to be able to put
lines in the the view any where like Html.ResourceManager.AddScriptFile("MyScript")
or Html.ResourceManager.AddCSSFile("MyCSS")
and at the end of the view call Html.Render(); this would then place the content of my resources at this point. My problem is that I want to put the CSS stuff at the top of the view, but them problem is that it is renderend at the end of the view, so I tought that I could use a ActionFilter to move it to the top of the view.
1) What would be the best way to do this task ?
2) Is there any resources that describe the way that the MVC framework works in more detail ?
MVC :: Action Filter Attribute Breaking Change?
Jan 20, 2011I have an app I am transitioning to MVC3 to see what the upgrade path is essentially. I've hit a snag. I believe I've run into a change that may be due to the changes for Dependency Injection in action filter attributes, but I have been unable to track down the cause, and the "correct" solution.This project uses StructureMap and NHibernate. The NHibernate session is started at the beginning of each request, and ends at the end of each request, thanks to a small module. This is just to give an idea of the stack involved...o I have a few custom Authorize attributes (Inheriting from AuthorizeAttribute) that perform some more complicated authorization logic for specific actions that they decorate. Part of their functionality involves using two repositories which they must either (a) have injected, or (b) get from the StructureMap ObjectFactory themselves. In MVC2 I was using option b, so that the CONSTRUCTOR of the attribute looked like this:
[Code]....
This worked fine, as in MVC2 the constructor was called each time the attribute was evaluated. This BREAKS in MVC3, where it would appear that this is no longer the case. Due to this apparent change, the FIRST time this attribute is evaluated, it runs fine, but each subsequent time, any calls in the repositories fails because it claims the NHibernate Session object hasn't been started! The reason being, as far as I can tell, that the CustomAuthorizeAttribute is created once, and then held in whatever state it exists in at that point for the lifetime of the application... Which means that the dependencies inside of it (Which SHOULD go out of scope at the end of each request, and be reinstantiated / fetched at the beginning of subsequent requests), are instead persisting with it becoming stale after the first evaluation.After banging my head against the desk for a few hours, I realized that simply moving these calls to the ObjectFactory into the AutorizeCore method made everything work again.Now, all of this was of course, a hack, because there wasn't a good easy to do real dependency injection into attributes in MVC2. I hear that is changed in MVC3, and I am wondering if this behavior is in response this change, and if so, what do I need to do to make this work?
MVC :: Why Synchronous Action Wasn't Executed Until Asynchronous Action Completed
Nov 29, 2010I'm implement Comet in Asp.net MVC, I used timer to keep Async request in server, Async request will complete when timer elapsed 1 minute and response to client (to avoid 404 error) and then reconnect to Async Controller. I also wanna execute some Synchronous action during Async request was holding, but the problem is: When an Async action was executed and hold by using timer, the Sync Action wasn't called until Async action (comet long-live request) completed. I did test with firefox 3.6 many times, but the result is the same, so strange, Do you know why ? I have a sub some questions : To implement comet, using timer (response after some minutes elapsed) or thread (response after several time sleeping thread) to hold async request, which is better?

Test That A Controller Action Simply Returns A Link To Another Action?
Apr 29, 2010Lets say I have a simple controller for ASP.NET MVC I want to test. I want to test that a controller action (Foo, in this case) simply returns a link to another action (Bar, in this case).How would you test TestController.Foo? (either the first or second link)
My implementation has the same link twice. One passes the url throw ViewData[]. This seems more testable to me, as I can check the ViewData collection returned from Foo(). Even this way though, I don't know how to validate the url itself without making dependencies on routing.The controller:
public class TestController : Controller

How To Pass Parameters To An Action Using Html.Action() In MVC?
Jun 30, 2010I've been using Html.Action("ActionName", "ControllerName") to invoke child actions across controllers without needing to have the view in ViewsShared. This has been working great for displaying things like session or cookie information.
Instead of just accessing cookies, I would like to pass additional parameters to Html.Action("ActionName", "ControllerName") so the action can execute different code based on the the data passed to the original view.
Should I be using a different method to pass parameters to a child action in a different controller?
MVC :: Controller Invokes GET Action Instead Of POST Action
May 20, 2010I'm trying to add file upload functionality to a page. I've got a form that posts the selected file to a controller with a 'savefile' method. But if I don't add a get version of 'savefile' I'll get a 404 error. Here is the form code which is presented on the Index page:
[Code]....
And here is the controller code:
[Code]....
Intuitively I don't think I should need a GET version of SaveFile but if omit it I get a 404 error when the form posts. Why should I need a GET version of SaveFile when all I want is to post a form and save the file?
