The problem is here:
crud.settings.delete_next = URL('course', args=unit.course)
form = crud.update(db.unit, unit.id,
next=URL('unit',args=unit.id))
the latter next overrides the former.
You can do:
ondelete_next = URL('course', args=unit.course)
form = crud.update(db.unit, unit.id,
next=URL('unit',args=unit.id),
ondelete=(lambda form, next=ondelete_next:
redirect(next)))
