comments not displaying in ruby on rails blog application - ruby-on-rails

Question

I'm trying to display commenter and body of comments model in blog application. But it is not displaying.
Here is the code of comments controller.
class CommentsController < ApplicationController
http_basic_authenticate_with :name => "dhh", :password => "secret", :only => :destroy
def create
#post=Post.find(params[:post_id])
#comment=#post.comments.create(params[:comments])
redirect_to post_path(#post)
end
def destroy
#post = Post.find(params[:post_id])
#comment = #post.comments.find(params[:id])
#comment.destroy
redirect_to post_path(#post)
end
def check
#comment=Comment.all
end
end
//comment model
class Comment < ActiveRecord::Base
belongs_to :post
attr_accessible :body, :commenter
end
//post model
class Post < ActiveRecord::Base
attr_accessible :content, :name, :title, :tags_attributes
validates :name, :presence=>true
validates :title, :presence=>true,
:length=>{:minimum=>5}
has_many :comments, :dependent=>:destroy
has_many :tags
accepts_nested_attributes_for :tags, :allow_destroy => :true,
:reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } }
end
// comment view
<p>
<b>Commenter:</b>
<%= comment.commenter %>
</p>
<p>
<b>Comment:</b>
<%= comment.body %>
</p>
<p>
<%= link_to 'Destroy Comment', [comment.post, comment],
:confirm => 'Are you sure?',
:method => :delete %>
</p>
// Post view
<p id="notice"><%= notice %></p>
<p>
<b>Name:</b>
<%= #post.name %>
</p>
<p>
<b>Title:</b>
<%= #post.title %>
</p>
<p>
<b>Content:</b>
<%= #post.content %>
</p>
<p>
<b>Tags:</b>
<%= join_tags(#post) %>
</p>
<h2>Comments</h2>
<%= render #post.comments %>
<h2>Add a comment:</h2>
<%= render "comments/form" %>
<br />
<%= link_to 'Edit Post', edit_post_path(#post) %> |
<%= link_to 'Back to Posts', posts_path %> |
Please fix this.

Answer 1

<%= render #post.comments %>
is incorrect. You must render partials, not objects.
I will think that your comment view in views/comments is named show.html.erb. Try something like that:
<%= #post.comments.map do |comment| %>
<%= render 'comments/show', comment: comment %>
<%= end %>
UPD: My mistake: it's correct, description in comments.

Answer 2

Which file is what you call 'comment view'? To be a able to render a collection like this
<%= render #post.comments %>
you need to place a comment template to views/comments/_comment.html.erb
Of course you can place it into another partial, e.g. 'posts/_comment.html.erb` but then you'll have to be more explicit:
<%= render :partial => 'posts/comment', :collection => #post.comments %>
(Mind there is an underscore in the file name, but not in the 'partial path' passed to render)
