Hi, everybody:  
I made a view - works as creating a new comment for a specific  
article, a example URL is “[http://localhost:3000/comments/new/2](http://localhost:3000/comments/new/2)”:  
here, comments is the controller, new is the action, 2 is the id of  
the specific article, which needs to be passed to next action  
“create”, so that this comment will be attached and displayed under  
2nd article. However, I didnt figure out how I can pass the id to next  
action named “create” in this controller, seems like only the  
“comments” is the only parameter when I click the “create” button…  
what can I do?

# the new view as follow:

# New comment

\<%= error\_messages\_for :comment %\>

\<% form\_for(@comment) do |f| %\>

**Desc**  
 \<%= f.text\_area :desc %\>

\<%= f.submit "Create" %\>

\<% end %\> ==================================

Thanks dudes!

Shortly I wanna deliver not only the “comments” but also the “id” as  
params to next action.

Pass the id to the URL that the form posts to.

\<% form\_for @comment, :url =\> {:id =\> @comment} do |f| %\>

good idea, RESTful… now I got to figure out how to do the nested  
URL in route.rb, but anyway, thanks for your comments!

Why not change the URL completely? Have it as /posts/2/comments/new?  
That  
way form\_for(@comment) _should_ generate the proper URL for it.

map.resources :posts, :has\_many =\> :comments

or if you’re not using Rails 2.0

map.resources :posts do |post|  
post.resources :comments  
end
