I have been working on implementing my own ORM. And I was wondering how the
rails path helper extracts the ID from the object. For example how would I
make this work for my ORM?
@contact = Contact.first
contact_path(@contact)
Any help would be greatly appreciated!

Active model is 2 things: reusable modules dealing with things such as validations, dirty attributes etc. and a protocol that classes should conform to. It''s the latter you''re interested in. There are only a handful of methods you have to implement, including (from memory) to_param, new_record? And a few others. There''s also an ActiveModel::Lint module that tests that your implementations of these primitives are valid. Once you have that you should be able to use the URL helpers, do stuff such as form_for(@contact) and so on Fred -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
