我无法使用自动生成的文档 ID 将数据批量上传到 firestore 子集合

Question

我正在尝试使用 firebase-admin sdk 更新子集合中的数据。但是，没有上传数据。

collection-name --> auto-gen-doc-key --> sub-collection-name --> auto-gen-doc-key --> datas

const admin = require('./node_modules/firebase-admin');
const serviceAccount = require("./serviceAccountKey.json");

const data = require("./data.json");
const collectionKey = "movies"; //name of the collection
const documentKey = "my-document-key";
const subCollectionKey = "listItem";

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: "https://my-database-url.firebaseio.com"
});

const firestore = admin.firestore();
const settings = { timestampsInSnapshots: true };
firestore.settings(settings);

if (data && (typeof data === "object")) {
    Object.keys(data).forEach(docKey => {
        firestore
            .collection(collectionKey)
            .doc(documentKey)
            .collection(subCollectionKey)
            .doc()
            .set(data[docKey])
            .then((res) => {
                console.log("Document " + docKey + " successfully written!");
            })
            .catch((error) => {
                console.error("Error writing document: ", error);
            });
    });
}

data.json 我尝试上传的文件，因为下面给出了子集合的文档。

设置多个文档时，我建议使用 batch writes，因为根据我的经验，当您在一个函数中编写超过 ~10 个文档时，文档往往不会得到 updated/set。

参考您的代码实现如下：

// IMPORT
const admin = require('./node_modules/firebase-admin');
const serviceAccount = require("./serviceAccountKey.json");
const data = require("./data.json");

// VAR DECLARATION
const collectionKey = "movies"; //name of the collection
const documentKey = "my-document-key";
const subCollectionKey = "listItem";

// INIT
admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: "https://my-database-url.firebaseio.com"
});
const firestore = admin.firestore();
const settings = { timestampsInSnapshots: true };
firestore.settings(settings);

// UPLOADING
if (data && (typeof data === "object")) {
    // CREATE BATCH WRITE
    var batch = firestore.batch();
    var path = collectionKey + "/" + documentKey + "/" + subCollectionKey;
    var id;

    // PRECREATE ID AND INSERT OPERATION INTO BATCH.
    data.forEach(dat =>{
        id = firestore.collection(path).doc().id;
        batch.set(firestore.collection(path).doc(id), dat);
    })

    // COMMIT THE OPERATIONS, MIGHT WANT TO CONVERT THIS TO AN ASYNC AWAIT FUNCTION TO ENSURE THIS FUNCTION FINISHES.
    batch.commit().then(res=>{
        console.log("COMMIT SUCCESSFUL!");
        return;
    }).catch(e=>{
        console.log(e.message);
    })
}
