我可以在视图中获取当前控制器的名称吗？ [英] Can I get the name of the current controller in the view?

问题描述

有没有办法从视图内找出当前控制器？

有一个例子，为什么我想知道这个：如果几个控制器共享相同的布局，我可能有一个部分在布局ERB文件，我想突出显示当前页面的菜单项基于控制器。

也许这是一个坏方法。如果是这样，更好的方法是这样做？

我有兴趣知道如何获得当前控制器的名称。 >

（显然我可以在每个控制器中加入 @controller_name ='users' ）

解决方案

Rails会在后台执行，所以我只是想知道是否有一个内置的方法。 params [：controller] 保存用于投放当前视图的控制器的名称。

Is there a way to figure out what the current controller is from within the view?

For an example of why I would want to know this: if several controllers share the same layout, I may have a part in the layout ERB file where I want to highlight the current page's menu item based on the controller.

Maybe that is a bad approach. If so, what is the more preferred way to do this?

I'm interested to know about getting the name of the current controller either way, though.

(Obviously I could put something like @controller_name = 'users' in each controller; but that seems like the sort of thing Rails would've already done behind the scenes. So I'm just wondering if there's a built-in way.)

解决方案

params[:controller] holds the name of the controller used to serve the current view.
