Rails 3.2.13/Devise 2.2.3：方法“authenticate_scope！”抛出错误：错误的参数数目（1 0）

Question

我使用的设计（2.2.3），我试图加载“编辑”的形式使用此jQuery的Ajax调用用户：

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

这将调用此的before_filter ...

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

...从宝石文件...

devise/app/controllers/devise/registrations_controller.rb 

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

多数民众赞成最终调用的方法是：

# 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 

而我得到的错误是：

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 
``` 

但是当我删除 “：力=> true”，则错误消失：

# 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 

所以我不知道什么是“：force => true”意味着......当我离开它时为什么会出现错误？ 我想这是一个坏主意，像这样猴子补丁宝石代码。但我还能做些什么来避免错误？

感谢您的帮助！

想通了：这个问题是我已经重写的方法...

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

    # then hand over to Devise's method 
    super 
end 

...在ApplicationController中。但它必须是这样的：

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

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