Rapidfire和Devise [英] Rapidfire and Devise

问题描述

我执行了Devise，并通过了安装Rapidfire
和应用程序控制器的说明，我有

  def current_user 
 current_user #rb：7 
 end 
 
 def can_administer 
 true＃只是现在... 
 end 
  

但在页面上我发现错误，如果我在控制台中看到，

  ActionView :: Template ::错误（堆栈级别太深）
 app / controllers / application_controller.rb：7 
  

这是 current_user 行。

$ b $你可以创建一个叫做 current_user的方法。

解决方案

，您将返回 current_user 的值。

Ruby不需要您调用方法时使用括号。

  current_user 
  

是相同的东西，如

  current_user（）
  

您正在一遍又一遍地调用 current_user 函数。

没有理由您定义一个名为 current_user 的方法，当devise给你。

I implemented Devise and went through the instructions to install Rapidfire and for the application controller I have

def current_user
  current_user  #rb:7
end

def can_administer
  true # just for right now...
end

but on the page I get a something went wrong and if I look in the console it says

ActionView::Template::Error (stack level too deep)
app/controllers/application_controller.rb:7

which is the current_user line.

Can anyone tell me whats going on?

解决方案

You are creating a method called current_user, and you are returning the value of current_user.

Ruby doesn't require that you use parenthesis when calling methods.

current_user

is the same thing as

current_user()

You are calling the current_user function over and over and over again.

There is no reason for you to define a method called current_user, when devise gives that to you.
