我正在做的升级是

• Ruby 2.6
• MongoDB 3.6
• Mongoid从5.0到7.1
• Rails从4.2到5.2

我有一个回调，在一定条件下停止未来的回调。现在我必须使用throw(:abort)来停止回调并阻止save操作，Mongoid将抛出：

Mongoid::Errors::Callback:

       message:
         Calling save! on Survey resulted in a false return from a callback.
       summary:
         If a before callback returns false when using Document.create!, Document#save!, or Document#update_attributes! this error will get raised since the document did not actually get saved.
       resolution:
         Double check all before callbacks to make sure they are not unintentionally returning false.

这是有问题的。我们甚至不期望一个错误消息，这是记录，我们继续前进。我们只想让record.save返回false。如何从Mongoid中抑制这个异常？
