django-modeltranslation导致django无法访问数据库

Question

我有一个 django rest 框架项目，其中已经创建了一些模型，我正在尝试将 django-modeltranslation 添加到项目中。我按照 django-modeltranslation 文档中指定的过程进行操作，但应用程序在使用 django-modeltranslation 修改进行迁移后停止工作。

每次我尝试访问 de 数据库时，无论是通过管理页面还是 django rest 框架页面，我添加 transalation.py 文件的应用程序都会出错。没有它的应用程序继续工作。

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完整回溯：

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