Answer 1

This answer is the first result on Google for 'factory girl shared association' and the answer from santuxus really helped me out :)

Here's an update with the syntax from the latest version of Factory Girl in case anyone else stumbles across it:

FactoryGirl.define do
  factory :relationship do
    guardian
    relationship_type RelationshipType.first

    after(:build) do |relationship|
      relationship.student = FactoryGirl.create(:student, school: relationship.guardian.school) unless relationship.student.present?
    end
  end
end

The unless clause prevents student from being replaced if it's been passed into the factory with FactoryGirl.create(:relationship, student: foo).
