如何将动态范围与设计和omniauth一起使用

Question

我正在将旧应用程序从 rails 3.0 升级到 rails 4.1，并且在设置设计和omniauth 的路线时遇到问题。目前的路线如下所示：

scope "(:locale)", locale: /#{I18n.available_locales.join("|")}/ do
      devise_for :users, controllers: {
            omniauth_callbacks: "users/omniauth_callbacks"
      }

当我运行它时，我收到以下错误：

 Devise does not support scoping omniauth callbacks under a dynamic segment (RuntimeError)
 and you have set "/(:locale)/users". You can work around by passing
 `skip: :omniauth_callbacks` and manually defining the routes. Here is an example:

match "/users/auth/:provider",
  constraints: { provider: /google|facebook/ },
  to: "devise/omniauth_callbacks#passthru",
  as: :omniauth_authorize,
  via: [:get, :post]

match "/users/auth/:action/callback",
  constraints: { action: /google|facebook/ },
  to: "devise/omniauth_callbacks",
  as: :omniauth_callback,
  via: [:get, :post]

我尝试了多种方式手动定义路由，但是当我运行测试时，我的路由都不起作用。有谁知道用 devise_for 处理这些动态段的正确方法吗？

Answer 1

我在 routes.rb

中添加了 devise_for 2 次

devise_for :users, skip: [:session, :password, :registration], controllers: { omniauth_callbacks: "users/omniauth_callbacks" }

scope ":locale", locale: /#{I18n.available_locales.join("|")}/ do
   devise_for :users, skip: [:omniauth_callbacks]

此外，您需要为omniauth 自定义故障块来处理登录期间的错误（例如用户取消）：

# In config/initializers/omniauth.rb
require 'devise/omniauth'
# Work around for bug when scoping paths
# See: https://github.com/spree/spree_social/issues/130
OmniAuth.config.on_failure = Proc.new do |env|
  env['devise.mapping'] = Devise.mappings[:user]
  controller_name  = ActiveSupport::Inflector.camelize(env['devise.mapping'].controllers[:omniauth_callbacks])
  controller_klass = ActiveSupport::Inflector.constantize("#{controller_name}Controller")
  controller_klass.action(:failure).call(env)
end

Answer 2

我想添加到设计的 wiki 上提供的解决方案：https://github.com/plataformatec/devise/wiki/How-To:-OmniAuth-inside-localized-scope

如果您已经在使用设置阶段（devise.rb 中的setup: true），您可以跳过创建新控制器（在他们的示例中为omniauth_controller.rb），只需将session[:omniauth_login_locale] = I18n.locale 添加到setup 操作。最终我的routes.rb 看起来像这样：

  devise_for :users, skip: [:session, :password, :registration, :confirmation], controllers: { omniauth_callbacks: 'omniauth_callbacks' }

  scope '(:locale)', locale: /en|zh/ do
    devise_for :users, skip: :omniauth_callbacks

    devise_scope :user do
      get 'auth/:provider/setup' => 'omniauth_callbacks#setup'
    end
  end
