Question

I am facing the same problem as the question here. The post is quite outdated. I was wondering how to do the same thing. My factory is:

FactoryGirl.define do
  factory :user do
    sequence(:email) {|n| "email#{n}@factory.com" }
    password "foobar"
    password_confirmation { |u| u.password }
    profile
  end
end

But FactoryGirl.create(:user) fails because of a validation error in the profile model with the user being blank.

Answer 1

What I would do is to use the after_create. This ensures it only creates profile after it creates user.

factory :user do
    sequence(:email) {|n| "email#{n}@factory.com" }
    password "foobar"
    password_confirmation { |u| u.password }
    after_create do |user|
      FactoryGirl.create(:profile, :user => user)
    end
  end

You can call Factory(:user) afterward.
