Creating a Blog ruby on Rails - Problem Deleting Comments

As I always type I am new to rails and programming in general so go easy. Thanks in advance.

I have successfully followed the initial tutorial from Ryan Bates on how to build a weblog in 15 minutes. If you don't know this tutorial takes you through creating posts and allowing for comments on those post. It even introduces AJAX through the creating and displaying comments on the posts show.html.erb page. All works great.

Here's the hiccup, when Ryan takes you though this tutorial he clears out the comments_controller and only shows the code for creating comments. I am trying to add back the ability to edit and destroy comments. Can't seem to get it to work, keeps deleting the actual post not the comment (log shows that I keep sending DELETE request to PostsController). Here is my code:

class CommentsController < ApplicationController
 def create
   @post = Post.find(params[:post_id])
   @comment = @post.comments.create!(params[:comment])
   respond_to do |format|
     format.html { redirect_to @post }
     format.js
   end
 end

 def destroy
    @comment = Comment.find(params[:id])
    @comment.destroy

    respond_to do |format|
      format.html { redirect_to(posts_url) }
      format.xml  { head :ok }
    end
  end
end

/views/posts/show.html.erb

    <%= render :partial => @post %>

    <p>
        <%= link_to 'Edit', edit_post_path (@post) %> |
        <%= link_to 'Destroy', @post, :method => :delete, :confirm => "Are you sure?" %> |
        <%= link_to 'See All Posts', posts_path %>
    </p> 

    <h2>Comments</h2>
    <div id="comments">
        <%= render :partial开发者_运维知识库 => @post.comments %>
    </div>

    <% remote_form_for [@post, Comment.new] do |f| %>
        <p>
            <%= f.label :body, "New Comment" %><br/>
            <%= f.text_area :body %>
        </p>
        <p>

<%= f.submit "Add Comment" %></p>
<% end %>

/views/comments/_comment.html.erb

<% div_for comment do %>
    <p>
        <strong>Posted <%= time_ago_in_words(comment.created_at) %> ago
        </strong><br/>
        <%= h(comment.body) %><br/>
        <%= link_to 'Destroy', @comments, :method => :delete, :confirm => "Are you sure?" %>
    </p>
<% end %>

routes.rb

ActionController::Routing::Routes.draw do |map|
  map.resources :posts, :has_many => :comments
  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'
end

meagar is on the right path, but since this is a nested route you have to do:

<%= link_to 'Destroy', [@post, comment], ... %>

So, you are passing the comment and the post and letting rails figure out the route based on your definitions.

In _comments.html.erb, change your link_to to

<%= link_to 'Destroy', comment, ... %>

IE, pass it the comment itself, not the entire @comments array.
