(Android) 如何在一对多关系中将子 ID 与父级匹配

我正在处理一个像one-to-many数据库这样的图像.

为了解释函数的流程，每当按下Add button时，列表中就会添加WorkoutSetInfo.(It is not inserted into DB.)

最后，当按下Save button时，Workout和WorkoutSetInfo list被插入DB.

我已经完成了设置Workout和WorkoutSetInfo之间的关系，但我不知道如何将每个Workout中的ID与Id(parendWorkoutId)WorktoutSetInfo匹配.

(现在，parendWorkoutId的所有ID都设置为1.)

我该怎么设置呢？

Workout

@Entity
data class Workout(
    @PrimaryKey(autoGenerate = true)
    val workoutId: Long,
    val title: String = "",
    var unit: String = "kg",
    val memo: String = "",
)

WorkoutSetInfo

@Entity(
    foreignKeys = [
        ForeignKey(
            entity = Workout::class,
            parentColumns = arrayOf("workoutId"),
            childColumns = arrayOf("parentWorkoutId"),
            onDelete = ForeignKey.CASCADE
        )
    ]
)
data class WorkoutSetInfo(
    @PrimaryKey(autoGenerate = true)
    val id: Long = 0,
    val set: Int,
    var weight: String = "",
    var reps: String = "",
    val parentWorkoutId: Long = 1 // How do I set this up?
)

WorkoutWithSets

data class WorkoutWithSets(
    @Embedded val workout: Workout,
    @Relation (
        parentColumn = "workoutId" ,
        entityColumn = "parentWorkoutId"
    )
    val sets: List<WorkoutSetInfo>
)

Repository

class WorkoutRepository(private val workoutDao : WorkoutDao, title: String) {
    val workout = Workout(0, title)
    private val setInfoList = ArrayList<WorkoutSetInfo>()
    
    fun add() {
        val item = WorkoutSetInfo(set = setInfoList.size + 1)
        setInfoList.add(item)
    }

    fun delete() {
        if(setInfoList.size != 0)
            setInfoList.removeLast()
        return
    }

    fun save() {
        workoutDao.insertWorkout(workout)
        workoutDao.insertSetInfoList(setInfoList)
    }
}
