Has_one belongs_to?

Rails
1

ok the models look like this:

class User < ActiveRecord::Base
has_one :address

class Address < ActiveRecord::Base
belongs_to :user

and my tables:

users has has the normal id field… and the addresses has user_id.

do I need a foriegn_key statement?

also the AR docs say the user_id should be automagicly populated…
if I have an account… and I’m logged in and create an address…
should it not get the user_id populated?

No, this is pretty rare. This is usually for odd joins or for legacy
table layouts.

also the AR docs say the user_id should be automagicly populated…
if I have an account… and I’m logged in and create an address…
should it not get the user_id populated?

If you create a new user via some_address.user.new() or
some_address.user.create() then everything will be linked together.

Easy as pie eh?

ok I’m a newbie and a newbie to OO programming!!!

here is what i got…

  1. the user creates an account via the restful_authentication gem
  2. i have created a table addresses with a user_id field
  3. setup the belongs_to has_one relationship
  4. after the user autherizes the account they can login and access the
    site
  5. and complete some forms about them selfs address etc…

what do i need to change when the address get saved to have it get
linked to the account

@address = Address.new(params[:address])
