Cloud 9 ruby on rails 制作文章时出错

Question

我收到一条错误消息：

https://i.stack.imgur.com/7mw12.png（这是错误的图片）

new.html.erb

<h1>  Create an article  </h1>
<%= form_for @article do |f| %>
<p>
<%= f.label :title %>
<%=f.text_field :title %>
</p>
<% end %>

articles_controller.rb

class ArticlesController < ApplicationController    

def new
@article = Article.new  

end

end

这是我的 routes.rb

Rails.application.routes.draw do
# The priority is based upon order of creation: first created -> highest 
priority.
# See how all your routes lay out with "rake routes".
# You can have the root of your site routed with "root"
# root 'welcome#index'
root 'pages#home'
get 'about', to: 'pages#about'
resources :articles

我不知道如何制作文章模型，如果我做了，我不知道该放什么...显示如果你能告诉我如何[在此处输入图片描述][，我将不胜感激1]

Answer 1

我想你还没有在模型文件夹中创建文章模型。因此它无法创建新对象。在您的模型文件夹中创建一个文件：

class Article < ApplicationRecord

end

然后尝试在 Article

上创建 .new 命令

Article.new
