Create a foreign table identifier with FactoryGirl - Rails

I have two models, User and Answer. I would like to generate a user_id in the FactoryGirl creation of Answer. How would I go about this?

FactoryGirl.define do
  factory :user do
    name { Faker::Name.name }
    pasword { 'password' }
    password_confirmation { |u| u.password }
  end
end

And the following is what I have so far for generating a foreign user_id (obviously incorrect syntax):

FactoryGirl.define do
  factory :answer do
    description { Faker::Lorem.words }
    user_id = FactoryGirl.create(:user)::user_id
  end
end

You could do something like the following:

FactoryGirl.define do
  factory :answer do
    description { Faker::Lorem.words }

    after(:build) do |answer, evaluator|
      answer.user = create(:user) unless answer.user
    end
  end
end

This will create a new user if a user isn't provided when creating the answer.

Given the association answer belongs_to: :user, you can use association helper in factory definition as:

FactoryGirl.define do
  factory :answer do
    description { Faker::Lorem.words }
    association :user
  end
end

Then the usage:

u = FactoryGirl.create(:user)
answer = FactoryGirl.create(:answer, user: u)
