设计Omniauth未定义方法omniauth_authorize_path

问题描述：

我注意到，登录到Devise时，我开始收到这些错误消息.

I've noticed that when logging to Devise I have started to receive these error message.

我正在将Devise 2.2.4与Omniauth 1.1.4和Omniauth-Facebook 1.4.1一起使用

I'm using Devise 2.2.4 with Omniauth 1.1.4 and Omniauth-Facebook 1.4.1

有人知道这个错误的原因吗?

Does anybody know what is the cause of this error?

答

一个可能的错误是omniauth配置设置在错误的位置.

One possible mistake is that omniauth configuration is set at the wrong place.

我遇到此错误是因为按照omniauth自述文件的指示，我在config/initializers/omniauth.rb中设置了我的Facebook帐户.

I encountered this error because I set my facebook accounts in config/initializers/omniauth.rb, as instructed by the omniauth readme.

但是，我们需要通过设计进行设置，即在omniauth部分的config/initializers/devise.rb.

However we need to set it through devise, i.e. config/initializers/devise.rb at the omniauth section.
