ruby-on-rails - 在Rails 3中找不到has_many的逆关联

我有以下型号：

class Business < ActiveRecord::Base
  has_many :customers, :inverse_of => :business
  has_many :payments, :inverse_of => :business
end

class Customer < ActiveRecord::Base
  belongs_to :business, :inverse_of => :customer
  has_many :payments, :inverse_of => :customer
end

class Payment < ActiveRecord::Base
  belongs_to :customer, :inverse_of => :payment
  belongs_to :business, :inverse_of => :payment
end

做business.customers很好。但是，当我business.payments时，我会得到一个错误：Could not find the inverse association for business (:payment in Business)。
但我不知道为什么。我对这两种方式有着完全相同的联想。我的schema.db看起来也不错。有什么问题吗？
编辑
当我为inverse_of => :business移除has_many :payments时，它会工作。为什么会这样？是否与客户和企业的付款有关（这应该不重要，对吧？）？

最佳答案

使用以下内容更新付款模式：

class Payment < ActiveRecord::Base
  belongs_to :customer, :inverse_of => :payments
  belongs_to :business, :inverse_of => :payments
end

你宣布
has_many :payments, :inverse_of => :business商业模式
但在付款时，您使用了belongs_to :business, :inverse_of => :payment
应该belongs_to :business, :inverse_of => :payments
