How to establish associations using FactoryGirl to test a Rails app

I'm just beginning to experiment with Rails tests. I'm having trouble getting started.

My first tests require a User, which I'm creating within FactoryGirl. But my model validates presence of an invitation.

class User
  has_many :sent_invitations, :class_name => 'Invitation', :foreign_key => 'sender_id'
  belongs_to :invitation
  validates_presence_of :invitation_id
end

class Invitation
  belongs_to :sender, :class_name => 'User'
  has_one :recipient, :class_name => 'User'
end

How do I generate an invited user using FactoryGirl?

I've tried a few approaches, but the association is not being set. The one that seems most likely to work is something like:

factory :invitation do
  token "MyInvitationToken"
  recipient_email "[email protected]"

  factory :invited_user do
    association :user, :factory => :user
  end
end

factory :user do
  email "[email protected]"
end

This is failing with Validation failed: Invitation is required.

What is the correct way to establish this association with FactoryGirl?

For bonus points, how can I modify this so the :invitation.recipient_email is a sequence sequence(:recipient_email) { |n| "test#{n}@example.com" }, and that this value gets passed to the invited_user's email column for each iteration.

you can use:

factory :user do
  email "[email protected]"
  f.association :invitation
end

OR

factory :user do
  email "[email protected]"

  after_build do |foo|
    user.invitations << Factory.build(:invitation)
  end
end
