问题
I recently started learning RoR. My problem is I get an unintended output when I call the post in the html.erb file.
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>
I get the list of posts I want below, but on top of the list is an array of posts I do not want outputted. Anyone know why this is happening?
Below is the output:
//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

You're outputting the contents of @posts because you're using <%=. You should change it to <%:
<% @posts.each do |p| %>
