Help: Should the comment.rb reside under plugins or in my app/models/comments folder?

[hariis]

The reason I ask is, the belongs_to :user association does not seem to work when I do this

comments_controller:
@comment = Comment.build_from(@post, @user.id, comment_body)
@comment.save
-the comment record is created properly in DB

In my view _comment.html.erb, the following chokes
<%= comment.user.name %>
Throws exception
undefined method `name' for "#<User:0xb590f7e4>":User

-name is a method I defined in user.rb

Any ideas greatly appreciated.

As of my latest Rails 3 update, if you run the generator, you will have a Rails.root/app/models/comment.rb.
