I have created a simple blog application with Ruby on Rails. The applications consists of two tables, posts and comments. Comments belongs_to :post and posts has_many :comments.
I created posts table with the following columns: title:string, body:text.
I created the comments table with the following columns: body:text post_id:integer name:string email:string
In the /views/comments/index.html.erb display I would like to show a listing of all comments w/ the post title as well. Currently, the index view only displays post_id, body, name, email.
How do I replace the post_id column with the corresponding post title? Here is my code:
CommentsController Index action:
def index
@comments = Comment.all :order => "created_at DESC"
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @comments }
format.json { render :json => @comments }
format.atom
end
end
/views/comments/index.html.erb
<h1>Listing comments</h1>
<table>
<tr>
<th>Post</th>
<th>Body</th>
</tr>
<% @comments.each do |comment| %>
<tr>
<td><%=h comment.post_id %></td>
<td><%=h comment.body %></td>
<td><%=h comment.name %></td>
<td><%=h comment.email %></td>
</tr>
<% end %>
</table>
<br />
