與FactoryGirl創建關聯

我有一個User has_many :accounts, through: :roles和User has_many :owned_accounts, through: :ownerships，我正在使用STI，其中Ownership < Roles。我無法爲Ownership型號和owned_account關聯編寫一個工作工廠，我的測試失敗。與FactoryGirl創建關聯

class User < ActiveRecord::Base 
    has_many :roles 
    has_many :accounts, through: :roles 
    has_many :ownerships 
    has_many :owned_accounts, through: :ownerships 
end 
class Account < ActiveRecord::Base 
    has_many :roles 
    has_many :users, through: :roles 
end 
class Role < ActiveRecord::Base 
    belongs_to :users 
    belongs_to :accounts 
end 
class Ownership < Role 
end

我有用戶，帳戶和角色的工作工廠;我不能寫一個擁有工廠和owned_accounts關聯，但是：

FactoryGirl.define do 
    factory :user do 
    name "Elmer J. Fudd" 
    end 
    factory :account do 
    name "ACME Corporation" 
    end 
    factory :owned_account do 
    name "ACME Corporation" 
    end 
    factory :role do 
    user 
    account 
    end 
    factory :ownership do 
    user 
    owned_account 
    end 
end

我開始用這些測試，但我得到一個未初始化的恆定誤差，所有的測試失敗：

describe Ownership do 
    let(:user) { FactoryGirl.create(:user) } 
    let(:account) { FactoryGirl.create(:owned_account) } 
    before do 
    @ownership = user.ownerships.build 
    @ownership.account_id = account.id 
    end 
    subject { @ownership } 
    it { should respond_to(:user_id) } 
    it { should respond_to(:account_id) } 
    it { should respond_to(:type) } 
end 

1) Ownership 
    Failure/Error: let(:account) { FactoryGirl.create(:owned_account) } 
    NameError: 
     uninitialized constant OwnedAccount 
    # ./spec/models/ownership_spec.rb:17:in `block (2 levels) in <top (required)>' 
    # ./spec/models/ownership_spec.rb:21:in `block (2 levels) in <top (required)>'

的錯誤消息是因爲您需要指定父級，或者它會假定工廠定義是針對該名稱的ActiveRecord類的。

factory :owned_account, :parent => :account do 
    name "ACME Corporation" 
end
