Rails 3.2.13/Devise 2.2.3：方法「authenticate_scope！」拋出錯誤：錯誤的參數數目（1 0）

Question

我使用的設計（2.2.3），我試圖加載「編輯」的形式使用此jQuery的Ajax調用用戶：

$.ajax({ 
    type: 'GET', 
    url: '/users/edit', 
    data: { 
    id: id 
    } 
}); 

這將調用此的before_filter ...

prepend_before_filter :authenticate_scope!, :only => [:edit, :update, :destroy] 

...從寶石文件...

devise/app/controllers/devise/registrations_controller.rb 

(see: https://github.com/plataformatec/devise/blob/master/app/controllers/devise/registrations_controller.rb) 

多數民衆贊成最終調用的方法是：

# Authenticates the current scope and gets the current resource from the session. 
def authenticate_scope! 
    send(:"authenticate_#{resource_name}!"), :force => true) 
    self.resource = send(:"current_#{resource_name}") 
end 

而我得到的錯誤是：

ArgumentError at /users/edit 
============================ 

> wrong number of arguments (1 for 0) 

(gem) devise-2.2.3/app/controllers/devise/registrations_controller.rb, line 116 
------------------------------------------------------------------------------- 

``` ruby 
    111  signed_in_root_path(resource) 
    112  end 
    113 
    114  # Authenticates the current scope and gets the current resource from the session. 
    115  def authenticate_scope! 
> 116  send(:"authenticate_#{resource_name}!", :force => true) 
    117  self.resource = send(:"current_#{resource_name}") 
    118  end 
    119 end 
``` 

但是當我刪除 「：力=> true」，則錯誤消失：

# Authenticates the current scope and gets the current resource from the session. 
def authenticate_scope! 
    send(:"authenticate_#{resource_name}!")) # deleted: :force => true 
    self.resource = send(:"current_#{resource_name}") 
end 

所以我不知道什麼是「：force => true」意味着......當我離開它時爲什麼會出現錯誤？ 我想這是一個壞主意，像這樣猴子補丁寶石代碼。但我還能做些什麼來避免錯誤？

感謝您的幫助！

想通了：這個問題是我已經重寫的方法...

def authenticate_user! 
    # do some stuff 
    # of my own here 

    # then hand over to Devise's method 
    super 
end 

...在ApplicationController中。但它必須是這樣的：

def authenticate_user!(options={}) 
    # do some stuff 
    # of my own here 

    # then hand over to Devise's method 
    super(options) 
end
