为需要身份验证的操作设计动作过滤器 [英] Devise action filter for actions that require authentication

问题描述

我正在使用devise进行身份验证，但是我无法查看和操作过滤器来指定需要用户登录的操作，这是否包含在设计宝石中？如果不是我可以创建一个，我有一个想法，但由于我是新的rails，我宁愿从一个更有经验的程序员首先看到一个解决方案。

I'm using devise for authentication, however I cant see and action filter for specifying actions that require the user to login, is this included in the devise gem? if not how could I create one, I kind of have an idea but since I'm new to rails I'd rather see a solution from a more experienced programmer first.

推荐答案

请参阅设计自述文件。

class PostsController < ApplicationController
  respond_to :html

  # Tell Devise that the #destroy action is
  #   special, and that the user must be
  #   authenticated in order to access the
  #   #desroy action.
  # Note that the name of the method here,
  #   #authenticate_user!, depends on the
  #   particular class/table that you have
  #   set up to be managed with Devise.
  before_filter :authenticate_user!,
    :only => [:destroy]

  before_filter :find_post!,
    :only => [:destroy]

  def destroy
    @post.destroy
    respond_with @post
  end

  private

  def find_post!
    @post = Post.find(params[:id])
  end
end
