I'm new to rails, so be nice.

I'm building a "rolodex" type application, and this question is about the best way to handle creating an entity along with several relationship entities at the same time.

For (a contrived) example: My application will have a Person model, which has_one Contact_Info model. On the create.html.erb page for Person it makes sense for the user of my appliction to create the person, and the contact_info at the same time.

It doesn't seem right to include details for creating a contact directly in the create view/controller for person. What's the rails way to handle this?
