swift - 如何编写Realm 嵌套对象？

Question

我有这个 Realm 结构:

class DateLog: Object {
    dynamic var date = NSDate()
    let workouts = List<WorkoutLog>()
    let activities = List<ActivityLog>()
}

class WorkoutLog: Object {
    dynamic var name = ""
    dynamic var value = 0
    dynamic var notes = ""
}

class ActivityLog: Object {
    dynamic var name = ""
    dynamic var value = 0
    dynamic var notes = ""
}

我如何将 DateLog > WorkoutLog 数据添加到 Realm ？(DateLog 的日期；WorkoutLog 的名称、值、注释)？

我正在寻找的工作流程:

1. 将新记录添加到日期日志(只是一个日期)
2. 添加该日期的锻炼日志记录(包含所有详细信息)
3. 添加同一日期的事件日志记录

只需在写入 block 中创建 DateLog 对象并将其添加到 Realm:

let realm = try! Realm()

try realm.write {
    var dateLog = DateLog()
    dateLog.date = NSDate()

    var workoutLog = WorkoutLog()
    workoutLog.name = "My Workout"
    workoutLog.value = 1
    workoutLog.notes = "my note"

    dateLog.workouts.append(workoutLog)

    realm.add(dateLog)
}
