I wrote the below code

    def prep(r):
        if (r.representation == 'json'):
            list_fields = ['id', 'priority_rank', 'color_code', 'severity', 'certainty', 'urgency', 'event_type_id', 'event_code', 'name']
            s3db.configure('cap_warning_priority', list_fields=list_fields)
        return True
    s3.prep = prep
    return s3_rest_controller()
