i18n与RenderAction [英] i18n with RenderAction

问题描述

我在视图中有一些片段，如下所示:

I have some fragments in a view as follows:

@Html.RenderAction("Foo","Home")

然后所有控制器都扩展BaseController

Then all the controllers extends BaseController

class HomeController : BaseController{

    protected override IAsyncResult BeginExecuteCore(AsyncCallback callback, object state)
    {
        .... // http://afana.me/post/aspnet-mvc-internationalization.aspx
    }
}

发生的是，对于每个RenderAction调用，也会执行一次.但这并不需要导致它们是子行为.如果我有3次RenderAction调用，则上面的代码将被执行3次，这是不应该的.

What happens is, for every RenderAction call, this is executed as well. But it doesnt need to cause they are child actions. If i have 3 RenderAction call, the above code is being executed 3 times, which it shouldn't.

我只需要每个请求执行一次.

I need this executed only once per request.

我该如何正确完成?还是应该将此代码放在其他地方?

How can i get this done properly? Or should i put this code somewhere else?

推荐答案

这是ASP.NET MVC设计的.这是一个模板方法，它将始终被调用.

This is by design from ASP.NET MVC. This is a template method, and it will always be called.

但是，如果出于性能原因要跳过代码执行(如果该调用是针对子操作的话).用以下if语句包装代码:

However, if you want to skip code execution for performance reasons if the call is for a child action. Wrap the code with an if statement like this:

protected override IAsyncResult BeginExecuteCore(AsyncCallback callback, object state)
    {    
      if (!ControllerContext.IsChildAction) {
       .....       
     }
}
