如何从云功能中移动 Firestore 文档? [英] How to move a firestore document from cloud functions?

问题描述

我有一个云功能，可以侦听集合中的文档更新.如果更新了特殊字段，我想将此文档移至另一个集合.

I have a cloud function which listens for document updates within a collection. If a special field is updated, I want to move this document to another collection.

我可以简单地更新文档的位置吗?

Can I simply update the location of the document?

或者我必须编写一个包含文档的 get()、write() 和 delete() 的事务，还是有更好的解决方案?

Or do I have to write a transaction which contains a get(), write() and delete() of the document, or is there a better solution?

这似乎是一个常见的用例，但我找不到任何文档.

That seems to be a common use case but I cant find any documentation.

推荐答案

Firestore 当前不提供移动"操作.您必须按照您在问题中的建议进行操作:在交易中自己复制文档.

Firestore currently doesn't offer a "move" operation. You'll have to do what you proposed in your question: copy the document yourself in a transaction.
