How pass the params :id to next action?

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”:
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!

Br,

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.

Really big hand!

map.resources :posts, :has_many => :comments

or if you’re not using Rails 2.0

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