我最近开始学习RoR。我的问题是当我在html.erb文件中调用帖子时,我得到了一个意外的输出。
1 class TestSiteController < ApplicationController
2 def Home
3 @greeting = 'Hello'
4 @posts = Post.all
5
6 respond_to do |format|
7 format.html
8 format.xml { render :xml => @posts }
9 format.json { render :json => @posts }
10 end
11 end
1 <h1>testsite#home</h1>
2 <%= link_to "contact", about_us_path %>
3
4 <table>
5 <%= @posts.each do |p| %>
6 <tr>
7 <td><%= p.topic %></td>
8 <td><%= p.post %> </td>
9 </tr>
10 <% end %>
11 </table>
我在下面找到了我想要的帖子列表,但在列表的顶部是我不想输出的帖子数组。任何人都知道为什么会这样吗?
以下是输出:
//Unwanted array
[#<Post id: 1, topic: "Rainy Day", post: "Today was a rainy day", created_at: "2012-03-29 21:22:43", updated_at: "2012-03-29 21:22:43">, #<Post id: 2, topic: "It works!", post: "Saving data from the rails console to the mysql db ...", created_at: "2012-03-29 21:25:18", updated_at: "2012-03-29 21:25:18">]
//List start
Rainy Day Today was a rainy day
It works! Saving data from the rails console to the mysql db work! I'm so ecstatic! :D
答案 0 :(得分:1)
您正在输出@posts
的内容,因为您正在使用<%=
。您应该将其更改为<%
:
<% @posts.each do |p| %>
