Question

最近将我的Rails应用程序更新为6.0。在运行测试时，我从Referral模型的范围中收到以下弃用警告：

DEPRECATION WARNING: Class level methods will no longer inherit scoping from `with_all_final_state_fulfillments` in Rails 6.1. To continue using the scoped relation, pass it into the block directly. To instead access the full set of models, as Rails 6.1 will, use `Referral.unscoped`. (called from block in <class:Referral> at /Users/home/workspace/APPNAME/app/models/referral.rb:60)

我所讨论的Referral模型范围很骇人，但写法是这样的：

  scope :with_all_final_state_fulfillments, lambda {
    final_state_ids = Referral.with_fulfillment_in_final_state.pluck(:id).uniq
    not_final_state_ids = Referral.where(id: final_state_ids).with_fulfillment_not_in_final_state.pluck(:id).uniq

    id_list = final_state_ids - not_final_state_ids
    Referral.where(id: id_list)
  }

我已经在互联网上搜索了有关如何解决此问题的建议，including the Rails GitHub PR进行了更改，但是在任何地方都找不到明确的English explanation。

如何为Rail 6.1修复此已弃用的范围？

Answer 1

通过将Referral.的内部范围调用更新为self.，使过时警告消失：

  scope :with_all_final_state_fulfillments, lambda {
    final_state_ids = self.with_fulfillment_in_final_state.pluck(:id).uniq
    not_final_state_ids = self.where(id: final_state_ids).with_fulfillment_not_in_final_state.pluck(:id).uniq

    id_list = final_state_ids - not_final_state_ids
    where(id: id_list)
  }

如何解决DEPRECATION警告：类级别的方法将不再从Rails 6.1中继承作用域？
