Question

在我的rails应用程序中，我基本上有一个＆＃34;帐户＆＃34;和＆＃34;交易＆＃34;模型。＆＃34;交易＆＃34;模型belongs_to＆＃34;帐户＆＃34;模型两次，一次为credited_account，一次为debited_account。它看起来像这样：

class Account < ActiveRecord::Base
  has_many :credits, :class_name => "Transaction", :foreign_key => 'credited_account_id'
  has_many :debits, :class_name => "Transaction", :foreign_key => 'debited_account_id'
# ... validators and such ... #
end

class Transaction < ActiveRecord::Base
  belongs_to :credited_account, :class => "Account"
  belongs_to :debited_account, :class => "Account"
end

这一切都有效，但我的规格遇到了一些问题。

使用RSpec和Factory_Girl，每次运行调用事务工厂的规范时，我都会收到TypeError。 Rspec输出如下：

Failure/Error: transaction = build(:transaction)
 TypeError:
   class or module required

下面是我的spec / factories.rb

  FactoryGirl.define do
  factory :account do
     #... account factory ...#
  end

  factory :transaction do
    association :credited_account, factory: :account
    #... other attributes set here ...#
    association :debited_account, factory: :account
  end
end

非常感谢任何见解！

此致

你应该改变

class Transaction < ActiveRecord::Base
  belongs_to :credited_account, :class => "Account"
  belongs_to :debited_account, :class => "Account"
end

到

class Transaction < ActiveRecord::Base
  belongs_to :credited_account, :class_name => "Account"
  belongs_to :debited_account, :class_name => "Account"
end

＆＃34;类型错误：所需的类或模块＆＃34;为了两对多的关系
