Rails 3 Nested Forms

Question

I have a Person model and an Address Model:

class Person < ActiveRecord::Base
  has_one :address
  accepts_nested_attributes_for :address
end


class Addr         


        

Answer 1

Why is your address built in your new action, and not in the create action? You're building an address from a non saved model, without an id, so the foreign key can't be set. You should keep your @person in your new action, but put your build_address in your create action, after @person has been saved.

Answer 2

You need to have accepts_nested_attributes_for :address on your Person model for this to work nicely. In your create action you can then do this:

def create
  @person = Person.new(params[:person])
  ...
end

Then Rails will take care of the rest.

UPDATE: if the address_id column is in the people table then it should be belongs_to :address, not has_one :address
