ruby-on-rails - 如何修复DEPRECATION WARNING : Class level methods will no longer inherit scoping from in Rails 6. 1？

Question

最近将我的Rails应用程序更新为6.0。当我运行测试时，我从Referral模型的作用域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模型范围是hacky，但是这样写:

  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清晰的 English explanation。

如何修复Rail 6.1的已弃用范围？

Answer 1

通过将Referral.的内部范围调用更新为self.来使弃用警告消失:

  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)
  }
