How to check if a Django model object gets locked?

Question

Is there any way to check if a Django model object is fetched using select_for_update()? Although 'locked' property in the following code does not exists actually, I want one like this.

with atomic():
   unlocked_obj = SomeModel.objects.get(pk=123)
   unlocked_obj.locked  # False

   locked_obj = SomeModel.objects.select_for_update().get(pk=123)
   locked_obj.locked  # True

Answer 1

The only way to check that is by including "select_for_update(nowait = True)", if it is locked, Django raise a DatabaseError.
