将对象分配给关联不起作用

Question

我的关系有以下模型：

class Account < ActiveRecord::Base
  has_one :business, :inverse_of => :account
end

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

class Customer < ActiveRecord::Base
  belongs_to :business, :inverse_of => :customers
end

account拥有business，business有许多客户与之关联。

在我的控制器中，在设置客户实例后，我尝试执行以下操作：

@customer.business = @account.business

检查@customer.business和@account.business时，一切正常。但是，当我尝试执行：@account.business.customers时，我总是得到一个空数组。

Answer 1

我假设您在分配了帐户业务后保存了客户？
