Ruby on rails 非预期布局输出-RoR 3.0.1.1

我最近开始学习RoR。我的问题是，当我调用html.erb文件中的post时，会得到一个意外的输出

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>

//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

我在下面得到了我想要的帖子列表，但在列表的顶部是一个我不想输出的帖子数组。有人知道为什么会这样吗

//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

以下是输出：

//Unwanted array

//不需要的数组

雨天今天是雨天
它起作用了！将数据从rails控制台保存到mysql数据库工作！我太高兴了D
