如何将具有自定义ID的文档添加到Firestore [英] How to add Document with Custom ID to firestore

问题描述

是否有机会使用自定义生成的ID(而不是Firestore引擎生成的ID)将文档添加到Firestore集合中?

解决方案

要使用自定义ID，您需要使用.set，而不是.add

这将创建一个ID为"LA"的文档:

db.collection("cities").doc("LA").set({
    name: "Los Angeles",
    state: "CA",
    country: "USA"
})

这摘自官方文档此处

Is there any chance to add a document to firestore collection with custom generated id, not the id generated by firestore engine?

解决方案

To use a custom ID you need to use .set, rather than .add

This creates a document with the ID "LA":

db.collection("cities").doc("LA").set({
    name: "Los Angeles",
    state: "CA",
    country: "USA"
})
