I have a firestore collections named users, each users have a generated id with a field score :
users
0e8X3VFL56rHBxxgkYOW
score : 4
3SeDjrgAWMmh3ranh2u
score : 5
I use redux-firestore and i want to reset all my users score at 0, something like
firestore.update({ collection: 'users' }, { score : 0 }
I can't achieve this because update method need a document id
Do you know how to do this ?
You can get all the documents in the collection, get their id's and perform updates using those id's:
db.collection("cities").get().then(function(querySnapshot) {
querySnapshot.forEach(function(doc) {
doc.ref.update({
capital: true
});
});
});
