Is there a way I can perform a delete on Firestore
documents where field1 =x and field2 = y?
I see the delete function
To achieve this, you need to create the desired query first and then just use the delete()
method like this:
FirebaseFirestore rootRef = FirebaseFirestore.getInstance();
CollectionReference itemsRef = rootRef.collection("yourCollection");
Query query = itemsRef.whereEqualTo("field1", "x").whereEqualTo("field2", "y");
query.get().addOnCompleteListener(new OnCompleteListener() {
@Override
public void onComplete(@NonNull Task task) {
if (task.isSuccessful()) {
for (DocumentSnapshot document : task.getResult()) {
itemsRef.document(document.getId()).delete();
}
} else {
Log.d(TAG, "Error getting documents: ", task.getException());
}
}
});
