rails way to transfer polymorphic object through url

Question

how do i pass a polymorphic object to another controller?

for example redirecting from messages/1/

to requests/new?object_type=message&object_id=1

or, second example, from files/154/

to requests/new?object_type=file&object_id=154

is

redirect_to new_request_path(:object_type => params[:controller].classify, :object_id => params[:id])

right?

Request model has

  belongs_to      :object , :polymorphic => true

Answer 1

You nest your routes, for example:

messages/1/requests/new
files/154/requests/new

redirect_to new_comments_request_path(Comment.find(1))

i accepted amikazmi's answer because information about routes nesting led me to polymorphic_url/polymorphic_path helper, which were response to my question
