Exclude a controller from before_action
提问by Matt C
I am using the before_actionfilter to call authenticatewhich is a method that will redirect users back to their home page if they aren't authorized to be on the page requested.
我正在使用before_action过滤器来调用authenticate这是一种方法，如果用户未被授权进入请求的页面，则将用户重定向回他们的主页。
I would like to exclude a page from this step, just for testing purposes.
我想从这一步中排除一个页面，仅用于测试目的。
What I have seen so far is that I can use exceptto exclude certain controller actions from being subject to the before_actionfilter so like:
到目前为止我所看到的是，我可以except用来排除某些控制器操作不受过before_action滤器的影响，例如：
before_action :authenticate, except: :demo_login
I can also exclude more than one action at a time like this:
我也可以像这样一次排除多个动作：
before_action :authenticate, except [:demo_login, :demo_show]
How can I exclude all actions in a specific controller?
如何排除特定控制器中的所有操作？
回答by Anthony E
Use skip_before_action :authenticatein the relevant controller.
使用skip_before_action :authenticate的相关负责人。
The format of this method is the same as before_actionso if you want to skip calling :authenticatefor a specific controller action, use:
此方法的格式与before_action如果您想跳过调用:authenticate特定控制器操作的格式相同，请使用：
skip_before_action :authenticate, only: [:show, :index]
skip_before_action :authenticate, only: [:show, :index]
The except:keyword can also be used.
该except:关键字也可以使用。
