Problem with associating comments with blog posts on same page

Hi,

I will admit I am very new to ruby and I am trying to do something that is not in any tutorials I have found. If you see a more conventional way to do some of the things I am trying to do, please let me know.

What I am trying to accomplish. People can edit the comments on the same page as the listing of posts. The problem is that when I go to create the comment, it is not getting associated with the post. I have accomplished this on other pages through normal methods such as:

app/views/posts/show.html.erb <% form_for [@post, Comment.new] do |f| %>

This successfully pulls the post id and saves the comment as belonging to that post.

Now, when I try to incorporate everything all into a very easy page to navigate I can't use the same code associations and my comments fail.

app/views/posts/index.html.erb <% div_for( post ) do %> <h3><%= link_to_unless_current h(post.title), statemant %></h3> <p class="timestamp">     Posted <%=h time_ago_in_words(post.created_at) %> ago </p> <p>   Approved: <%= h(post.approved) %>   </p> <p class="post_post">     <%= simple_format h(post.body) %> </p> <% randomNumber = rand(100000) %> <img src="/images/add_comment.jpg" class="add_comment_image<%= randomNumber %>" />   <div id="comments<%= randomNumber %>">       <%= render :partial => post.comments %>     <h1>New comment</h1> <% form_for :comment,       :url => { :controller => "comments", :action => :create} do |f| %>   <%= f.error_messages %>   <%= f.hidden_field(:post_id, :value => post.post_id) %>   <p>     <%= f.text_area :body %>   </p>   <p>     <%= f.submit 'Add your Comment' %>   </p> <% end %>   </div> <% end %>

Thanks for any help or pointers. I hope that you can understand what I am trying to accomplish.

Justin
