Rails - Feb 2009 - Making things DRY: RESTful address controller

Hello list,

I''m developing an e-commerce application, and the Checkout controller
has an
edit_address and create_addresses method. I''m not expert in any
RESTful-based architecture (including the Rails implementation) but this
just doesn''t feel right. I would rather have a Addresses controller to
create and edit addresses, create a resource out of it, and nest it as
needed for any other resource that needs it (by making it polymorphic,
something like this:
http://www.pathf.com/blogs/2008/07/drying-up-rails-controllers-polymorphic-and-super-controllers/).


To edit an address, I would then just POST to
http://url/addresses/idinstead of POSTing to checkout/edit_address/.
Much simpler and **DRY**.
Would also clean up the checkout controller, removing from it the
responsibilities of editing addresses...

However, in one of the checkout steps, I need to create two addresses in
only one request (billing and shipping addresses) - as there is a screen
with two addresses forms so the user can input their addresses. These
addresses need to be created in the account (account has one billing address
and has one shipping address). I would rather not create an edit_addresses
action in the addresses polymorphic controller, but I see no other way of
receiving the input of this form and updating both addresses at the same
time.

What do you think?

Thanks,

Marcelo.
