Question

我正在编写一个Rails应用程序，该应用程序具有用于登录的root_path和用户应在登录后重定向到的配置文件路径，或者如果他们已经登录并访问主页。我还希望将未登录的用户始终重定向到登录页面，因此我设置了一个before_filter来尝试这样做。不幸的是，它并没有捕捉到任何东西。谁能解释我做错了什么？

应用程序控制器

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery

  before_filter :require_login

  private
    def current_user
      @current_user ||= User.find(session[:user_id]) if session[:user_id]
    end

    def require_login
      unless current_user
        redirect_to root_url
      end
    end

    helper_method :current_user, :require_login
end

会话控制器

class SessionsController < ApplicationController
  skip_before_filter :require_login

  def index
    if current_user
      redirect_to profile_path
    end
  end

  def create
    user = User.from_omniauth(env["omniauth.auth"])
    puts(env["omniauth.auth"])
    session[:user_id] = user.id
    redirect_to profile_path
  end

  def show
  end

  def destroy
    session[:user_id] = nil
    redirect_to root_url
  end
end

路线

Fbapp::Application.routes.draw do
  root to: "sessions#index"

  match 'profile', to: 'sessions#show', as: 'profile', via: [:get, :post]
  match "auth/:provider/callback", to: "sessions#create", via: [:get, :post]
  match "auth/failure", to: redirect('/'), via: [:get, :post]
  match 'signout', to: 'sessions#destroy', as: 'signout', via: [:get, :post]
  resources :posts

删除

 skip_before_filter :require_login

来自SessionsController

目前，SessionsController skip_before_filter中的所有操作都会从之前的过滤器链中删除require_login过滤器。因此，永远不会被称为。

顺便说一句，您可以使用：only和：except选项控制操作以跳过过滤器，就像应用过滤器一样。

skip_before_filter : require_login, :only => [:method_name]

或

skip_before_filter : require_login, :except => [:method_name]

Rails before_filter没有重定向
