If you don't call '_get_next_id()' from any class methods (in other 
words, if you don't need to ever say 'self._gen_next_id()') then you can 
remove the '@staticmethod':

     def _get_next_id():
       [blah, blah, blah]
       return id

     user_id = IntField(required=True, default=_get_next_id)

If you do need to sometimes call it from a method then still leave off 
the '@staticmethod', and give 'self' a default of 'None':

     def _get_next_id(self=None):
       [blah, blah, blah]
       return id

     user_id = IntField(required=True, default=_get_next_id)
