Я выполнил каждый шаг по добавлению нового столбца базы данных в postgresql, однако, когда я нажимаю кнопку, чтобы сохранить информацию в базе данных postgresql после заполнения выделенного текстового поля, ничего не происходит. Информация не сохраняется. Я пытаюсь понять, почему, но на данный момент безуспешно. Есть идеи, почему это не работает? Как обычно, признательны за отзывы.
Внешний интерфейс: Jetpack Compose
Внешний интерфейс: приложение Flask
База данных: Postgresql
ОБС! Если потребуется какая-либо дополнительная информация, дайте мне знать, и я обновлю код!
RelationshipModel:
@Keep
@Entity(tableName = "UserRelationDB", indices = [Index(value = ["id"], unique = true)])
@Serializable
data class UserRelationshipModel(
@PrimaryKey
val id: Int? = null,
val relationship: String? = null,
)
Модель отношений с пользователем:
@Serializable
class UserRelationModel (
val users:List
)
Interface UserService (Содержит все методы публикации и получения пользовательских данных из всех трех других столбцов базы данных. Это связано с AppModule!):
@POST("relationshipData")
suspend fun postUserRelationshipData(@Body data: UserRelationshipModel): Response
class:
class UserApi @Inject constructor(
private val userService: UserService,
private val webSocketManager: WebSocketManager
) {
suspend fun postRelationshipsData(data: UserRelationshipModel): Response {
return userService.postRelationshipsData(data)
}
}
пользовательский репо:
class Repo @Inject constructor(private val userApi: UserApi) {
suspend fun postRelationshipsData(data: UserRelationshipModel): Response {
return userApi.postRelationshipsData(data)
}
}
Интерфейс Дао:
@Dao
interface UserRelationshipDataModelDao {
@Insert(onConflict = OnConflictStrategy.REPLACE)
suspend fun insertUserRelationship(user: UserRelationshipModel)
@Update
suspend fun updateUserRelationship(user: UserRelationshipModel)
@Query("SELECT * FROM UserRelationDB WHERE id = :userId")
suspend fun getUserById(userId: Int): UserRelationshipModel?
@Query("SELECT * FROM UserRelationDB LIMIT 1")
suspend fun getLoggedInUser(): UserRelationshipModel?
@Query("DELETE FROM UserRelationDB")
suspend fun deleteAllUsers()
}
