如何访问/删除 Firestore 中随机创建的文档 ID？

Question

Code for deleting something (not working with this.task.id or this.task)

const docRef = firebase.firestore().collection('users').doc(firebase.auth().currentUser.uid)
docRef.collection('tasks').doc(this.task.id).delete()

Answer 1

It looks like you are not handling the promise with a then or async/await, like the docs indicate https://cloud.google.com/firestore/docs/manage-data/delete-data#node.js .

Also, your code implies the tasks are nested within the individual users document. If this is not the case, you might be referencing the wrong collection entirely. I suggest first doing a .get().then(res => console.log(res)) for both the user & their task. If you can't get the document, you can't delete it.
