我有一个模型，我正在尝试向它添加一个外键字段。

这是字段定义：

part_of_speech = models.ForeignKey('PartOfSpeech', help_text=_('Translation | part_of_speech | help_text'), verbose_name = _('Translation','part_of_speech'))

当我尝试执行makemigrations命令时，出现以下错误：

Migrations for 'dictionary':
  0024_translation_part_of_speech.py:
    - Add field part_of_speech to translation

帮助文本声明（对 ugetttext 的调用）格式不正确。为了解决这个问题，改变这个：

verbose_name = _('Translation','part_of_speech')

对此：

verbose_name = _('Translation | part_of_speech')
