在云功能中添加多个文档

问题描述

我想在sampleData集合中添加多个文档吗?另外，sampleData上有一个serverTimeStamp属性，我该如何添加它.

I want to add multiple documents in the sampleData collection?Also, there is a serverTimeStamp property on the sampleData, how can I add this as well.

sampleData看起来像:

sampleData looks like:

名称:字符串

serverTimeStamp:serverTimeStamp

serverTimeStamp: serverTimeStamp

标签:数组[]

exports.newUserSignup = functions.auth.user().onCreate((user) => {

    const p1 = admin.firestore().collection('users').doc(user.uid).collection('score').add({
        gems: 0,
    })

    const p2 = admin.firestore().collection('users').doc(user.uid).collection('sampleData').add({
        ...
    });

    return Promise.all([p1, p2]);
})

推荐答案

到添加文档，您可以使用.doc().set(...)，也可以使用.add(...)(完全等效).

To add a document you may use .doc().set(...) or as in your case .add(...), which are completely equivalent.

如果要添加多个文档，则可能需要考虑批量写入.因为您将能够作为一个批处理执行多个写操作，而这些批处理包含set()，update()或delete()操作的任意组合.可以通过此文档.

If you are looking to add multiple documents, you may want to consider batch writes. As you would be able to execute multiple write operations as a single batch that contains any combination of set(), update(), or delete() operations. More information can be found through this documentation.
