我有一个用户Devise + Omniauth允许用户通过Facebook注册的应用程序.我还使用Carrierwave允许用户上传他们自己的个人资料图像并处理从Facebook请求的图像.因此,我在控制器和用户模型中具有以下功能:

user.rb

def self.find_for_facebook_oauth( data, signed_in_resource=nil)
user = User.where(:email => data.info.email).first
unless user
  params =
    {  
      :user =>
      {
        :username => data.uid,
        :email => data.info.email,
        :password => Devise.friendly_token[0,20],
        :user_profile_attributes => 
          {
            :first_name => data.info.first_name,
            :last_name => data.info.last_name,
            :remote_image_url => data.info.image
          },
        :user_auths_attributes =>
        [{
          :uid => data.uid,
          :provider => data.provider
        }]
      }
    }
    user = User.create!(params[:user])
end
return user
end

# You need to implement the method below in your model (e.g. app/models/user.rb)
@user = …
