undefined方法_path（NoMethodError）

当我尝试访问包含创建post的表单的页面时，我在Rails应用程序中收到以下错误。 我正在尝试在他的示例应用程序中实现类似于Michael Hartl的Micropostfunction的function：

NoMethodError in Home#index undefined method `posts_path' for #<#:0xb60013b8> 

这是索引视图页面，其中包含插入表单的代码：

_post_form.html.erb：

这是Home控制器：

  class HomeController  "Welcome #{current_user.email}!" @users = User.all @post = current_user.posts.build if signed_in? end end 

我可以在查看代码时使用一些帮助。 我正盯着它，我需要别人为我审查。 我是Rails的新手，如果我没有提供必要的信息，请原谅我。

附加信息：我正在使用Devise gem来处理用户身份validation。

谢谢！

编辑：我添加了错误的控制器。

Routes.rb文件：

 AppName::Application.routes.draw do #get "users/index" #get "users/show" authenticated :user do root :to => 'home#index' end root :to => "home#index" devise_for :users resources :users do member do get :following, :followers, :posts end end resources :works resources :relationships, only: [:create, :destroy] end

您需要添加resources :posts routes.rb文件中的resources :posts ，以便Rails自动为您创建posts_path帮助程序。

添加resources :posts将生成适当的RESTful路由，供您创建，删除，更新和获取posts 。 请查看Ruby on Rails指南以获取路由，特别是此处有关路由和RESTful路由的部分。
