ruby-on-rails-3 - 找不到 Users::OmniauthCallbacksController 的操作 'google_oauth2'

Question

我正在使用“omniauth-google-oauth2”登录 google 并仔细遵循此处的所有说明

   https://github.com/plataformatec/devise/wiki/OmniAuth%3A-Overview

但我上面有错误。

我的路线

    devise_for :users, :controllers => {
      :omniauth_callbacks => "users/omniauth_callbacks"

    }

devise.rb代码

  config.omniauth :google_oauth2, "863625299460- 420n6c7lvad91dfvko60uamtvtr6huhf.apps.googleusercontent.com", "dcvA2aZRZi27KCQjWTYP30pw", {  access_type: "offline", approval_prompt: "" }

omniauth 回调 Controller 代码

     def google_oauth2
       #@user = User.find_for_google_oauth2(request.env["omniauth.auth"], current_user)
       binding.pry #control not coming here
     end

回调后出现以下错误。看截图

这看起来像是一个路由问题。如果你执行“rake routes | grep auth”你会看到什么？
