问题 Is the following composite where(in:) and where(isEqualTo:) query possible in Firebase Firestore? (Swift) let taskDocIds = ["0ArJnMgTfDkvolUcZR8E", "0cdcZsfaEJQpsiByJIgH"] return db.collection("tasks") .whereField("status", isEqualTo: "approved") .whereField(Firebase.FieldPath.documentID(), in: taskDocIds) .limit(to: 100) .getDocuments(as: TaskModel.self) My security rules enforce that only tasks with status as approved may be read.

How do I code this up properly? let addAction = UIAlertAction(title: "Add Workout", style: .default) { (UIAlertAction) in if self.dayCount != 0 { print("\(self.dayCount)") self.colRef.addSnapshotListener { (querySnapshot, err

问题 Confusion with Firestore billing never ends! Lets say I have an Android app with bottom navigation, in which, one of the menus is displying some documents from a collection using a real-time listener. Now, it is very common for user to jump from one nav-menu to other in a short period of time. This is handled by replacing fragments, resulting in creation of new Query object on each onStart . Similar situation may happen in case of Activities. This answer says that for every new Query object,

问题 So on signup, the user will enter their name, username, along with the email and a password. On submit, the user's email and id are the only things that are delivered to Firebase but profileName is "" and username is null. I'm only expecting a value for username and profileName, everything else should still be "". This is from SignUpPage.dart I'm not sure if I did that loggedInUser part right by adding username: user.displayName and profileName: user.displayName. I did that because I saw
