如何從Rails 3.07中的過濾器中排除單個控制器動作？

Question

class ApplicationController < ActionController::Base 
    protect_from_forgery 
    before_filter :check_session_expiry, :except => :login 

你如何排除單控制器（用戶控制器，例如）登錄動作？

Answer 1

class ApplicationController < ActionController::Base 
    before_filter :check_session_expiry 


    def check_session_expiry 
    return true if self.class != UsersController && self.action == "login" 
    # do your thing 
    end 

Answer 2

首先，我不是軌測試它的機器上，但下面應該工作：

class UserController < ApplicationController 
    skip_filter :check_session_expiry, :only => :foo 

    # following is DEPRECATED as far as I know 
    #skip_before_filter :check_session_expiry, :only => :foo 

    def foo 
    end 
end 

Answer 3

我只想重新定義check_session_expiry在你的控制器是一個空的方法。

class UserController < ... 
    ... 
    private 
    def check_session_expire 
     # optional if other actions shall still use the filter 
     super unless self.action == 'login' 
    end 
    end
