Rails - Best-Practice: How to create dependent has_one relations

Question

Could you tell me whats the best practice to create has_one relations?

f.e. if i have a user model, and it must have a profile...

How could i accomplish that

Answer 1

Your solution is definitely a decent way to do it (at least until you outgrow it), but you can simplify it:

# user.rb
class User < ActiveRecord::Base
  has_one      :profile
  after_create :create_profile
end
