MVC HTML.RenderAction – Error: Duration must be a

问题:

On my website I want the user to have the ability to login/logout from any page. When the user select login button a modal dialog will be present to the user for him to enter in his credentials.

Since login will be on every page, I thought I would create a partial view for the login and add it to the layout page. But when I did this I got the following error: Exception Details: System.InvalidOperationException: Duration must be a positive number.

There are other ways to work around this that would not using partial views, but I believe this should work.

So to test this, I decided to make everything simple with the following code:

Created a layout page with the following code

@{Html.RenderAction("_Login", "Account");}

In the AccountController:

public ActionResult _Login()
{
    return PartialView("_Login");
}

Partial View _Login

<a id="signin">Login</a>

But when I run this simple version this I still get this error: Exception Details: System.InvalidOperationException: Duration must be a positive number.

Source of error points to "@{Html.RenderAction("_Login", "Account");}"

There are some conversations on the web that are similar to my problem, which identifies this as bug with MVC (see links below). But the links pertain to Caching, and I'm not doing any caching.

Caching ChildActions using cache profiles won't work? Caching ChildActions using cache profiles won't work?

I'm not sure if this makes a difference, but I'll go ahead and add it here. I'm using MVC 3 with Razor.

Answer Thanks Darin Dimitrov

Come to find out, my AccountController had the following attribute

[System.Web.Mvc.OutputCache(NoStore =true, Duration = 0, VaryByParam = "*")].

I don't believe this should caused a problem, but when I removed the attribute everything worked.

Adding my comment as answer:

Hmm, that's weird. By reading your question I am ready to bet 5 bucks that you have caching enabled somehow. Try renaming the action, controller. Make sure that the action you are calling is not decorated with the [OutputCache] attribute. Try doing this in a new project that you start from scratch. I am sure you will be able to narrow it down.

回答3:

I got around the problem by creating a custom OutputCache attribute, that manually loads the Duration, VarByCustom and VarByParam from the profile:

public class ChildActionOutputCacheAttribute : OutputCacheAttribute
{
    public ChildActionOutputCacheAttribute(string cacheProfile)
    {
        var settings = (OutputCacheSettingsSection)WebConfigurationManager.GetSection("system.web/caching/outputCacheSettings");
        var profile = settings.OutputCacheProfiles[cacheProfile];
        Duration = profile.Duration;
        VaryByParam = profile.VaryByParam;
        VaryByCustom = profile.VaryByCustom;
    }
}

The advantage of this approach is that you get to still keep all your profiles in just one place in the web.config.

In some cases it may be appropriate to just create a second action method, with caching disabled that is called by your primary action.

    /// Use this for normal HTTP requests which need to be cached
    [OutputCache(CacheProfile = "Script")]
    public ContentResult Foo(string id)
    {
        return _Foo(id);
    }

    /// Use this for Html.Action
    public ContentResult _Foo(string id)
    {
        return View();
    }

When you need Html.Action you just call _Foo instead of Foo.

@Html.Action("_Foo", "Bar").ToString();

You can then rely on the parent page to do the caching.

Another way is to just bypass the whole 'CacheProfile' thing for ActionMethod and use my 'DonutCacheAttribute' instead.

The 'CacheProfile' for ActionMethods currently only respects the Duration and varyByParam properties - and this method makes it easy to set different caching durations in debug vs. deployment (assuming you're using XDT transformations).
