迁移到OmniAuth 1.0:未定义的方法`user_omniauth_authorize_path'

Question

试图将我的应用程序从Rails 3.0迁移到3.2,作为其中的一部分,我也在更新Devise gem.原来,新的Devise需要新的OmniAuth宝石.我有使用OmniAuth配置的Facebook授权.阅读迁移指南后,我还添加了omniauth-facebook gem并在devise.rb中进行了配置.

现在我收到这个错误:

ActionView :: Template :: Error(##:0x00000003b01e88>的未定义方法`user_omniauth_authorize_path')

我正在使用这条路径登录Facebook登录按钮.我现在该怎么用？

用户模型包含此(user.rb):

 # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable, :lockable and :timeoutable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable,
         :omniauthable

更新:好的,我设法解决了这个路径问题.现在点击Facebook登录按钮,我得到了这个:

Started GET "/users/auth/facebook" for 127.0.0.1 at 2012-02-23 16:02:01 +0200

NoMethodError (undefined method `include?' for nil:NilClass):

  warden (1.1.1) lib/warden/manager.rb:34:in `catch'
  warden (1.1.1) lib/warden/manager.rb:34:in `call'

这一切都有点令人困惑.在我指定了本教程中的:facebook params之后解决了路径问题:https://github.com/plataformatec/devise/wiki/OmniAuth :-Overview .现在我也注意到我在config/initializers文件夹中缺少omniauth.rb,这在omniauth-facebook wiki中有提到.我用以下内容创建了omniauth.rb,但仍然遇到同样的问题:

Rails.application.config.middleware.use OmniAuth::Builder do
    provider :facebook, ENV['APP_ID'], ENV['APP_SECRET']
  end

我通过再次运行设计生成器解决了这个问题.需要验证的两个文件是:config/routes.rb和models/user.rb

在routes.rb文件中,顶部会有一个重复的'devise_for',而user.rb将有默认的设计模块,因此需要在这里添加'omniauthable'.
