Сохранение списка строк в Firestore ⇐ Android

[Anonymous]

Я работаю над тем, чтобы сэкономить время, которое выбирается пользователями. Выбранные времена должны быть спасены в Firestore. В моих журналах log.d («Firestoresave», «Saving Place: $ placeinfo») показывает, что Times также создает область доступного времени в Firestore, но массив выглядит пустым. Также другие входы от пользователя, показанные без проблем. < /P>
Мой класс данных < /p>

Код: Выделить всё

data class PlaceData(
val name: String = "",
val capacity: Int = 0,
val id: String = "",
val placeImageUrl: String = "",
val availableTimes: List = emptyList() // Firestore can handle this
):Serializable
< /code>
Репозитория реализация < /p>
override suspend fun addPlace(placeData: PlaceData): Flow = flow {
emit(RootResult.Loading)
try {
val currentUser = firebaseAuth.currentUser
val userId = currentUser?.uid
if (userId != null) {
val placeId = firestore.collection("users").document(userId).collection("places")
.document().id

// Create a map of the data to save
val placeInfo = mapOf(
"name" to placeData.name,
"capacity" to placeData.capacity,
"id" to placeId,
"placeImageUrl" to placeData.placeImageUrl,
"availableTimes" to placeData.availableTimes // Ensure this is a List
)

Log.d("FirestoreSave", "Saving place: $placeInfo")

// Save the data to Firestore
firestore.collection("users").document(userId).collection("places")
.document(placeId).set(placeInfo, SetOptions.merge())
.addOnSuccessListener {
Log.d("FirestoreSave", "Place saved successfully!")
}
.addOnFailureListener { e ->
Log.e("FirestoreSave", "Failed to save place: ", e)
}

emit(RootResult.Success(true))
} else {
emit(RootResult.Error("User ID is null"))
