ActiveRecord::RecordInvalid: Validation failed for FactoryGirl

Question

I want to generate a :stake factory that belongs to a :topic and a :group. The :topic should belong to a :group (as :owner_group) and in this case it should be the same :group (as the one :stake belongs to). Topic also belongs to :membership. In short, I want this to set up valid objects:

it 'should set up all the factories' do
  member = FactoryGirl.create(:membership)
  topic  = FactoryGirl.create(:topic, owner_group: member.group, membership: member)
  stake  = FactoryGirl.create(:stake, group: member.group, topic: topic)
end

But I get the error:

Failure/Error: stake = FactoryGirl.create(:stake, group: member.group, topic: topic) ActiveRecord::RecordInvalid: Validation failed: Group has already been taken

Here are my factories:

factory :user
  sequence(:email) { |n| "foo#{n}@bar.com" }
end

factory :group
  name Faker::Company.name

  factory :owner_group
  end
end

factory :membership
  user
  group
end

factory :topic
  owner_group
  membership
end

factory :stake
  group
  topic
end

topic.rb has this association:

belongs_to :owner_group, class_name: "Group", foreign_key: "group_id"

I've remedied similar errors in the past with rake db:test:prepare, which doesn't work. I've also configured spec_helper.rb with the database_cleaner gem. So I suspect it's how I've set up my factories.

Is there anything in my factory associations or the way I'm creating the objects that's causing this error?

So it sounds like there is already a Stake with that same Group. I don't see a problem with the factory definition. I would check your test database to make sure the stakes table is empty, but that's probably not the issue. Do you have a before block that is creating a Stake? Or perhaps Topic or Group have an after_create callback that creates an initial Stake automatically?
