I don't understand why not the invalidators' error_message only use English. eg. class IS_NOT_EMPTY(Validator): def __init__(self, error_message='enter a value', empty_regex=None):
why not class IS_NOT_EMPTY(Validator): def __init__(self, error_message=T('enter a value'), empty_regex=None): I don't want to assign every IS_NOT_EMPTY's error_message.
