Rails - Dec 2013 - Link posts and comments on a new view/controller

Hello everyone,

I''m a newbie following the
http://guides.rubyonrails.org/getting_started.html , so far everyone is
working without problems except a modification that I made earlier.

I''ve created a view called welcome that act as main content page where
I
list all the posts, going a bit further I created a new model called
comments with its own controller. At this point I''m stuck because
I''m
unable to include the comments into the welcome/index view.


This is the content of comments_controller.rb


class CommentsController < ApplicationController
  def create
    @post = Post.find(params[:post_id])
    @comment = @post.comments.create(params[:comment].permit(:commenter,
:body))
    redirect_to post_path(@post)
  end
end



And this is the welcome/index.html.erb

<h1>My posts</h1>

<table>
  <tr>
    <th>Title</th>
    <th>Text</th>
  </tr>

  <% @posts.each do |post| %>
    <tr>
      <td><%= post.title %></td>
      <td><%= post.text %></td>
      <td><%= link_to ''View/Post Comments'', post
%></td>

    </tr>
  <% end %>
</table>


<p>
<%= link_to "Admin", controller: "posts" %>



Any clue how to include the comments into the index page?


Sorry again for the noob question.

Phillip

Just sorted out using Nested Eager Loading.




       <% post.comments.each do |comment| %>
        <td><%= comment.commenter %></td>
        <td><%= comment.body %></td>
