如何在Firebase Firestore中更新文档ID? [英] How to update the document ID in firebase firestore?

问题描述

在我的Firestore数据库中，我已将用户的电子邮件作为文档密钥.如果我想执行db.collection('users').doc('email_id')来执行某些操作，该怎么办.现在的问题是，当用户更新其电子邮件ID时，我找不到任何方法来更新Firestore中的document id.

in my firestore database, I've made the user's email as the document key. Do if I want I cal do db.collection('users').doc('email_id') to perform some action. Now the problem is when the user is updating their email id, I am not finding any way to update the document id in firestore.

我试图做

db.collection('users').doc(old_email).update({
  id: new_email
})

但是实际上创建了一个名为id的新字段，该新电子邮件作为该文档中的值，而不是更新实际的document id，以便我可以在doc()中传递它并获得与用户相同的数据.

But that actually created a new field called id with the new email as value inside that document instead of updating the actual document id so that I can pass it within doc() and get the same data about the user.

有人知道怎么做吗?如果是这样，请分享.

Does anyone know how to do it? If so, please do share.

在发布此问题之前，我检查了google和firestore文档，但未找到任何更新文档ID的方法.请帮忙.

before posting this question I have checked google and firestore docs but didn't find any way to update the document id. Please help.

推荐答案

我不认为有一种更改文档ID的方法，但是即使有某种方法，您所做的事情也绝对是错误的.该ID应该是唯一标识符，让自己成为UserID字段，例如，使用Firebase Auth使用firebase.Auth().currentUser.uid作为Firestore中用户特定的已保存数据的ID.

I dont think there is a way to Change the Document ID, but even if there is a way what you do is horribly wrong. The ID should be a Unique Identifier, make yourself a UserID Field, for example with Firebase Auth use firebase.Auth().currentUser.uid as the ID of your User specific saved data in the Firestore.

我建议您总体上进行更改，以解决您的问题，更重要的是为您提供坚实的结构. (身份验证中的UID是唯一的)

I Suggest you to Change that in General that solves your Problem and more importantly gives you a solid structure. (The UID from the Auth is Unique)
