使用nodejs从firestore文档中删除字段

Question

我尝试从 Firestore 文档中删除字段，但没有成功。

我已经搜索了收到的错误消息，但我可以找到的几页链接指向我已经在做的事情。我确信这很简单，但我现在不知所措。

const Firestore = require('@google-cloud/firestore');
const admin = require('firebase-admin');
const FieldValue = admin.firestore.FieldValue;

const firestore = new Firestore({
  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
});
const settings = {timestampsInSnapshots: true};
firestore.settings(settings);


var updateDoc = firestore.collection('XXXXXXXX').doc('XXXXXXX').update({
    fieldToBeDeleted: FieldValue.delete()
}); 

我希望删除该字段，但我收到以下错误消息：

Error: Update() requires either a single JavaScript object or an alternating list of field/value pairs that can be followed by an optional precondition. Argument "dataOrField" is not a valid Document. Couldn't serialize object of type "DeleteTransform". Firestore doesn't support JavaScript objects with custom prototypes (i.e. objects that were created via the 'new' operator).

Answer 1

显然，您不能在 Cloud SDK 和 Firebase Admin SDK（包装了 Cloud SDK）之间混合使用符号。Firebase 导出自己的符号，这些符号不能用于直接转至 Cloud SDK 的调用。呼叫者必须使用其中之一，但不能同时使用两者。

编辑：

以下是最终运行的代码，仅使用 Cloud SDK，而不使用 Firebase Admin SDK。

const Firestore = require('@google-cloud/firestore');

const firestore = new Firestore({
  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
});
const settings = {timestampsInSnapshots: true};
firestore.settings(settings);


var updateDoc = firestore.collection('XXXXXXXX').doc('XXXXXXX').update({
    fieldToBeDeleted: Firestore.FieldValue.delete()
});
