django-modeltranslation 导致 django 无法访问数据库

Question

我有一个已经创建了一些模型的 django rest 框架项目，我正在尝试将 django-modeltranslation 添加到项目中。我按照 django-modeltranslation 文档中指定的流程进行操作，但是在使用 django-modeltranslation 修改进行迁移后，应用程序停止工作。

每次我尝试访问数据库时，无论是通过管理页面还是 django rest 框架页面，我都收到我添加 transalation.py 文件的应用程序错误。没有它的应用程序将继续工作。

这是我的模型：

class Country(models.Model):
    name = models.CharField(max_length=40, unique=True, verbose_name=_('Name'))
    code = models.CharField(max_length=5, verbose_name=_('Code'))
    calling_code = models.CharField(max_length=3, null=True, blank=True, verbose_name=_('Calling code'))

    class Meta:
        verbose_name = _('Country')
        verbose_name_plural = _('Countries')

    def __str__(self):
        return self.name

这是我的translation.py

@register(models.Country)
class CountryTranslationOptions(TranslationOptions):
    fields = ('name',)

这是我得到的错误的全部追溯：

我将不胜感激。

谷歌搜索错误 (;)) 导致我找到 https://github.com/deschler/django-modeltranslation/issues/436 – 如果我假设正确，您使用的是 Django 2.0，并且尚未发布的 django-modeltranslation 版本支持它。
