我如何从 Firestore 文档中获取所有数据？

Question

Before you tell me to read the docs , I have. I've tried the examples on there and I haven't gotten it to work.

I am simply trying to get all of the data from the muted section of my database and be able to check if they're still muted. (Basically I need to get their UserId, guild ID, mute start, and mute end data.)

From the docs I've tried:

const mutedDB = db.collection('muted');
const queryRef = mutedDB.where('stillMuted', '==', true);
console.log(queryRef)

^ Returns ^

and

const mutedDB = db.collection('muted');
const snapshot = mutedDB.where('stillMuted', '==', true).get();
if (snapshot.empty) return console.log('None')  
        
snapshot.forEach(doc => {
  console.log(doc.id, '=>', doc.data());
});

^ Returns an error ^

I'm unsure if I did those correctly, please let me know if there's a way to fix/solve this!

Answer 1

get() returns a promise that yields a DocumentSnapshot. It does not itself return a DocumentSnapshot. You need to wait on the promise to fulfill in the usual JavaScript way:

const promise = mutedDB.where('stillMuted', '==', true).get();
promise.then(snapshot => {
    if (snapshot.empty) {
        console.log('None');
        return;
    }
    snapshot.forEach(doc => {
        console.log(doc.id, '=>', doc.data());
    });
}

This is spelled out in the documentation that you linked, so I would still actually recommend that you go back and study the docs again.
