自动加载常数时检测到循环依赖用户 [英] Circular dependency detected while autoloading constant User

问题描述

我遵循了本教程（ http://railscasts.com/episodes/236 -omniauth-part-2 ）用于通过OmniAuth和Devise创建Facebook登录，并且我得到这个错误：自动加载常量时检测到循环依赖用户在我的routes.rb中

I've followed this tutorial (http://railscasts.com/episodes/236-omniauth-part-2) for creating facebook login with OmniAuth and Devise and I get this error: Circular dependency detected while autoloading constant User in my routes.rb

  devise_for :users , :controllers => {:registrations => 'registrations'}

registrationrations_controller.rb

registrations_controller.rb

Class RegistrationsController < Devise::RegistrationsController

  def create
    super
    session[:omniauth] = nil unless @user.new_record?
  end

  private

  def build_resource(*args)
    super
    if session["devise.omniauth"]
      @user.apply_omniauth(session["devise.omniauth"])
      session["devise.omniauth"] = nil
   end
  end
end

这里是我的来自AuthenticationsController的创建方法

and here's my create method from AuthenticationsController

def create
    omniauth = request.env["omniauth.auth"]
    authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
    if authentication
      flash[:notice] = "Signed in successfully."
      sign_in_and_redirect(:user, authentication.user)
    elsif current_user
      current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid'])
      flash[:notice] = "Authentication successful."
      redirect_to authentications_url
    else
      user = User.new
      user.apply_omniauth(omniauth)
      if user.save
        flash[:notice] = "Signed in successfully."
        sign_in_and_redirect(:user, user)
      else
        session[:omniauth] = omniauth.except('extra')
        redirect_to new_user_registration_url
      end
    end
end

推荐答案

你的 registrations_controller.rb 保存到？位置很重要。我发现我把一个错误保存到 app / controllers / devise /.中。它只需要保存在 app / controllers /.中，例如：

Where was your registrations_controller.rb saved to? The location is important. I found that I was making a mistake saving it to app/controllers/devise/.. It simply needed to be saved in app/controllers/. e.g.:

controller / registrations_controller.rb

另外， config / routes。 rb 路由应定义为：

devise_for：用户，控制器：{注册：'注册'}

devise_for :users, controllers: { registrations: 'registrations' }
