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.
