There's so much wrong with what I see here I don't know where to start. You really need to study the Model-View-Controller (MVC) design pattern. Otherwise you'll never get Rails to work for you as it was designed to do.

But, here are the top five things I see wrong:

5. Request is probably a bad name for a model class in web applications. It's could be too easily confused with the actual HTTP request object.

4. The request_id appears to be an instance method, but you're showing it called on the Comment class.

3. Don't manipulate primary and foreign keys directly. Manage associations through association manipulation methods.

@comment = @request.comments.build(:title => "Learn MVC", :author => "Robert")

@request.comments << an_existing_comment

Note: What you see here is controller code not view code.

2. Fetching data IS NOT the responsibility of the view.

RequestController (request_controller.rb)

Thank you all for your warm response!!! I got the solution. Its something like below

<% form_for [@request, Comment.new] do |f| %>           <p>             <%= f.hidden_field :request_id, :value => @request.id %>     ...................................           </p>           ................................................................................. <% end %>

You can avoid the hidden field if you setup a nested route for request/ ##/comments.
