ruby-on-rails-4 - Google omniauth 无法识别路径

Question

我对 omniauth-google-oath2 gem 有疑问。

我的代码:

devise.rb

config.omniauth :google_oauth2, 'app_id','secret'

omniauth_callbacks_controller.rb

def google_oauth2
   auth = env["omniauth.auth"]

   @user = User.find_for_google_oauth2(request.env["omniauth.auth"], current_user) 
   if @user.persisted?
     flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google"
     sign_in_and_redirect @user, :event => :authentication
   else
     session["devise.google_uid"] = request.env["omniauth.auth"]
     redirect_to new_user_registration_url
   end
end

我还在我的 user.rb 模型中为 find_for_google_oauth2 提供了方法。在我的 html.erb 中我写道:

<%= link_to "With Google", user_omniauth_authorize_path(:google_oauth2) %>

最后我有这个错误:没有路由匹配 {:controller=>"omniauth_callbacks", :action=>"passthru", :provider=>:google_oauth2, :format=>nil} missing required键:[:provider]

我的错误在哪里？感谢您的任何预付款!

检查用户模型

devise :omniauthable, omniauth_providers: [:google_oauth2]

它可能丢失或错误。
