Ruby on rails Rails作为嵌套的多个关联不工作

当我经过阵列时

user.as_json(
  include: [
    user_purchased_packages: {
      include: [
        business_package: {
          include: [
            business: {
              include: :business_address
            },
            package: {
              include: :services
            }
          ]
        }
      ]
    }
  ]
)

因此，它期望业务和包的两个对象值都应该出现

但是我只能得到业务对象，包对象不会出现。

user.as_json（include:{:user\u bookings=>{include:[:business\u category\u service\u sub\u services，：business=>{include:：business\u address}]，方法：[:date format][user\u purchased\u packages=>{:include=>[:business\u package=>{:include=>{include:：services}，：business=>{include:：business\u address}}]，方法：[:date\u format]}，方法：[:followers\u count，：following\u count，：full\u name]）

[:business=>{:include=>:business_address},:package=>{:include=>:services}]
