Problem with Factory_girl, association and after_initialize

Question

I have a Family class so defined:

class Family < ActiveRecord::Base
  after_initialize :initialize_family
  belongs_to :user
  validates :user, 
       :prese         


        

Answer 1

Since after_initialize is triggered after new objects are instantiated and factory_girl builds instances by calling new without any arguments by default, you must use initialize_with to overwrite the default build.

FactoryGirl.define do
  factory :family do
    initialize_with { new(user: build(:user)) }
  end
end
