ruby-on-rails - 设计 1.5 + Omniauth 1.0 + Facebook : undefined method `extra`

Question

我正在尝试让我的 Cucumber 测试与 Devise 1.5 和 Omniauth 1.0 一起使用，并使用 Facebook 身份验证。有趣的是，它在开发模式下工作，但是当运行 Cukes 测试时，它失败并显示以下消息:

undefined method `extra' for #<Hash:0x007f95f0d26260> (NoMethodError)
./app/models/user.rb:13:in `find_for_facebook_oauth'
./app/controllers/users/omniauth_callbacks_controller.rb:4:in `facebook'
(eval):2:in `click_link'
./features/step_definitions/web_steps.rb:58:in `/^(?:|I )follow "([^"]*)"$/'
features/facebook_auth.feature:11:in `When I follow "Sign in with Facebook"'

对应的方法如下:

def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)

    data = access_token.extra.raw_info
    if user = User.where(:email => data.email).first
        user
    else 
        User.create!(:email => data.email, :password => Devise.friendly_token[0,20]) 
    end
end

为了让 Cukes 测试全部变为绿色，我必须采用此变通方法，这会破坏开发模式代码。所以现在，我正在这样做:

    case Rails.env
    when "test"
        data = access_token['extra']['user_hash']
        if user = User.find_by_email(data["email"])
            user
        else 
            User.create!(:email => data["email"], :password => Devise.friendly_token[0,20])
        end
    else
        data = access_token.extra.raw_info
        if user = User.where(:email => data.email).first
            user
        else 
            User.create!(:email => data.email, :password => Devise.friendly_token[0,20]) 
        end
    end     

似乎违规行是 data = access_token.extra.raw_info。

我 mock Facebook 哈希的方式是:

OmniAuth.config.add_mock(:facebook, {
    :uid => '12345',
    :nickname => 'zapnap',
    :extra => {
      :user_hash => {
        'email' => 'someone@webs.com'
      }
    }
  })

我通过将 OmniAuth.config.test_mode = true 附加到 test.rb 的最后一行来启用它。

任何想法将不胜感激!

您可以将设置放在 spec_helper.rb 中，作为 stub_env_for_omniauth 方法的替代方法。

  OmniAuth.config.test_mode = true
  OmniAuth.config.full_host = 'http://example.com'

  omni_hash = {
    'uid' => '12345',
    'provider' => 'facebook',
    "info" => {
      "email" => Faker::Internet.email,
      "image" => "http://example.com/pic.img"
     },
    "extra" => {
      "raw_info" => {
        "first_name" => Faker::Name.first_name,
        "last_name" => Faker::Name.last_name,
        "name" => Faker::Internet.user_name,
        "gender" => "male",
        "locale" => "en"
      }
    }
  }
  OmniAuth.config.mock_auth[:facebook] = OmniAuth::AuthHash.new(omni_hash)
