"Type Error: class or module required" for two-to-many relationship

Question

在我的 rails 应用程序中，我基本上有一个 "account" 和一个 "transaction" 模型。 "transaction" 模型 belongs_to "account" 模型两次，一次是 credited_account，一次是 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

一切正常，但我运行遇到了一些关于我的规格的问题。

使用 RSpec 和 Factory_Girl，每次我运行一个调用事务工厂的规范时，我都会得到一个 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！

Answer 1

你应该改变

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

至

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