Я пишу одновременно и в мою базу данных Firebase Realtime, и в облачное хранилище пожаров.
Первоначально у меня было поле с именами POJO "user_id". Недавно я изменил на «creator_id» в моем POJO, и когда я записываю POJO с измененным полем в базу данных, он появляется как «creator_id». Тем не менее, он все еще записывается в Firestore как «user_id». Не уверен, есть ли проблема с моим кодом:
mBaseRef.updateChildren(childUpdates);
Collections.reverse(mPollAnswers);
for (int i = 0; i < mPollAnswers.size(); i++) {
mBaseRef.child("Polls").child(key).child("answers").child(String.valueOf(i + 1)).updateChildren(poll.answerConvert(mPollAnswers, i));
}
String userID = FirebaseAuth.getInstance().getCurrentUser().getUid();
Log.v("USER_ID", userID);
mUserRef.child(userID).updateChildren(childUpdates);
mStoreBaseRef.collection(POLLS).add(poll).addOnCompleteListener(new OnCompleteListener<DocumentReference>() {
@Override
public void onComplete(@NonNull Task<DocumentReference> task) {
if (task.isSuccessful()) {
DocumentReference docRef = task.getResult();
String key = docRef.getId();
Log.v("KEY", key);
Toast.makeText(getApplicationContext(), key, Toast.LENGTH_LONG).show();
CollectionReference pollAnswerRef = mStoreBaseRef.collection("Polls").document(key).collection("answers");
//TODO: need to add answers
for (int i = 0; i < mPollAnswers.size(); i++){
pollAnswerRef.document(String.valueOf(i + 1)).set((poll.answerConvert(mPollAnswers, i)), SetOptions.merge());
}
}
}
});
