将数据从 Android Kotlin API 记录到房间

Question

I want to save data to Room. There is a string, there is an int but there is also a List. I wonder if there is a way to save the listed structures in Room?

data class Model(
    var ranking: Int? = null,
    var team_name: String? = null,
    var coach: String? = null,
    var market_value: String? = null,
    var image: String? = null,
    var next_week_opponent: NextWeekOpponent? = null,
    var last_week_opponent: LastWeekOpponent? = null
)

Answer 1

Room can handle collections and based on what value is passed, it returns single row ID or list of all the row IDs inserted. The response object needs be mapped with the entity. For example response data class:

data class ApiResponse(
    val intValue: Int,
    val stringValue: String,
    val sources: List<SomeList>
)

val response = apiService.getSomeList()

appDatabase.someDummyDao.insertAll(response.someList)

Room can save/retrieve list.

  @Insert
    fun insertAll(vararg list: SomeList): List<long>

  @Query("select * from some_table")
    fun getSavedList(): List<SomeList>
