Question

我一直在努力将用户（登录后）重定向到之前的网址。但是我收到了以下错误：

Filter chain halted as :require_no_authentication rendered or redirected

所以我在网上看到它，我看到在会话控制器中预先设置过滤器可以解决问题：

class SessionsController < Devise::SessionsController
  prepend_before_filter :require_no_authentication, only: [ :new, :create ]
end

但我仍然遇到同样的错误。有没有其他方法可以解决这个问题？

应用程序控制器

  after_filter :store_location

  def store_location
    # store last url - this is needed for post-login redirect to whatever the user last visited.
    if (request.fullpath != "/users/sign_in" &&
        request.fullpath != "/users/sign_up" &&
        request.fullpath != "/users/password" &&
        !request.fullpath.match("/users") &&
        !request.xhr? && # don't store ajax calls
        request.format == "text/html" || request.content_type == "text/html")
      session[:previous_url] = request.fullpath 
      session[:last_request_time] = Time.now.utc.to_i
    end
  end

  def after_sign_in_path_for(resource)
    session[:previous_url] || root_path
  end

的routes.rb

  devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks", :registrations => "registrations" }, :skip => [:sessions] 
  as :user do
    get 'login' => 'devise/sessions#new', :as => :new_user_session
    post 'login' => 'devise/sessions#create', :as => :user_session
    delete 'logout' => 'devise/sessions#destroy', :as => :destroy_user_session
  end

Answer 1

设计会话控制器已为:require_no_authentication和:new添加了:create。在我的代码中，我有一个save_last方法，就像你的store_location一样，在application_controller.rb中定义为before_action。

Answer 2

除非您需要覆盖Devise的控制器，否则无需使用它们，但如果您确实需要，请删除prepend_before_filter :require_no_authentication。

这是我用于重定向到上一个网址的内容：

# app/controllers/application_controller.rb
after_action :store_location

# If you are requiring authentication for all your controllers you can use
#   before_action :authenticate_user! unless: :devise_controller?
# and disable particular actions in other controllers with
# require_no_authentication (except on any DeviseController)


private

  def after_sign_in_path_for(resource)
    stored_location_for(resource) || dashboard_path
  end

  def after_sign_out_path_for(resource_or_scope)
    new_user_session_path
  end

并且

# config/routes.rb
devise_for :user

authenticated :user do
  root to: 'sistema/inicio#tablero_de_mando', as: :authenticated_user_root
end

root to: 'some_controller#some_action'

您可以在控制器上使用authenticate_user!或require_no_authentication和before_action / before_filter，具体取决于天气，或者您不需要对该控制器的特定操作进行身份验证。

设计prepend_before_filter：require_no_authentication无效
