Mapper save on MappedLongForeignKey

[Brent Lemons]

Is there a way to cascade a save when I have an object that extends
MappedLongForeignKey?

For example, let's say I have the following relationship:

val myName: Name = Name.create.given("test").family("name")
val myPerson: Person = Person.create.name(myName)

If I say myPerson.save, it inserts a null value in the person table
for the name. If I say myName.save prior to assigning it to the name
in person, then everything is great.

I'd rather not have to insert each entity individually. Is there a
way to cascade the insert of the name object?

Thanks,
Brent

One option: Make your FK mix in LifecycleCallbacks and override def afterSave {obj.foreach(_.save)}
Not sure how that interacts with save's success return value. Another option: in the Mapper class,

override def save = super.save && fk.obj.dmap(true)(_.save)

This will return true if super.save returns true, and also either fk.obj is empty or its mapper's save returns true.

It will return false if either super.save returns false, or if both fk.obj is full and its mapper's save returns false.

It will only try to save the foreign mapper if super.save returns true.

Thank you for the quick reply! I'll give both a shot and see what
works best for me.
