在用户确认帐户后覆盖重定向路径 - Devise

Question

我希望发生的情况是，一旦用户单击确认链接，并成功确认他们的账户，如果他们有特定的角色分配（在User模型上的after_create回调中已成功分配），则应将他们重定向到某个指定路径。

我创建了一个RegistrationsController：

class RegistrationsController < Devise::RegistrationsController
  protected

  def after_sign_up_path_for(resource)
    if resource.has_role? :seller
      new_item_path
    else
      root_path
    end
  end
end

但是，这总是重定向到root_path......尽管我已经验证了，用户确实拥有该角色。

似乎确认请求从未发送到RegistrationsController：

Started GET "/users/confirmation?confirmation_token=KRwZ7MChtxxq4sxxkDLq" for 127.0.0.1 at 2013-05-07 03:52:56 -0500

这是我的routes.rb文件的内容：

  devise_for :users, :path_names => { :sign_up => "register", 
                                      :sign_in => "login", 
                                      :sign_out => "logout",
                                      :settings => "settings" },
                      :controllers => { :registrations => "registrations" }

  devise_scope :user do
    get "login", :to => "devise/sessions#new"
    get "register", :to => "registrations#new"
        get "settings", :to => "devise/registrations#edit"
    get "logout",   :to => "devise/sessions#destroy"    
  end

资源是否等于用户？ - ahmet

我相信是这样的。这就是devise使用的方式。 - marcamillion

最终我想通了。

我不得不创建一个ConfirmationsController.rb类，覆盖Devise的确认控制器。

class ConfirmationsController < Devise::ConfirmationsController
  protected
    def after_confirmation_path_for(resource_name, resource)
      if resource.has_role? :seller
        new_item_path
      else
        root_path
      end
    end
end

接下来在我的routes.rb文件中：

  devise_for :users, :path_names => { :sign_up => "register", 
                                      :sign_in => "login", 
                                      :sign_out => "logout",
                      :settings => "settings" },
                      :controllers => {:confirmations => "confirmations"}

  devise_scope :user do
    get "login", :to => "devise/sessions#new"
    get "register", :to => "devise/registrations#new"
    get "settings", :to => "devise/registrations#edit"
    get "logout",   :to => "devise/sessions#destroy"    
  end

对我来说，那似乎很好用。

Answer 2

你在 model user.rb 中写了 role 方法吗？如果没有，你应该写一个 role 方法。

或者，在 User 类的 user.rb 中顶部写上 rolify。

是的，我已经验证了该用户确实拥有该角色。 - marcamillion

Answer 3

你是否已经编写了以下内容，以告诉Devise使用重写的控制器而不是默认控制器？

在config/routes.rb中： devise_for :users, :controllers => {:registrations => "registrations"}

- Murhari

是的。我已经更新了我的routes.rb文件。 - marcamillion

在注册控制器中编写load_and_authorize_resource。 - Murhari

您可以参考http://stackoverflow.com/questions/7624385/custom-registrations-controller-for-devise-not-overriding-create-action。 - Murhari

这会抛出一个错误 - 未初始化的常量Register。此外，它与Devise自己的建议相反：https://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-up-(registration)。 - marcamillion
