Description:
 def create(cls, fields=None, **fields_kwargs):
 """ create an instance of cls with the passed in fields and set it into the db fields -- dict -- field_name keys, with their respective values **fields_kwargs -- dict -- if you would rather pass in fields as name=val, that works also """

        # NOTE -- you cannot use hydrate/populate here because populate alters modified fields
        instance = cls(fields, **fields_kwargs)
        instance.save()
        return instance
