我改变了我的models.py，之后，我不能做python manage.py迁移，我有一个错误，当我运行此命令。我不明白这是什么字符串值Incorrect string value: '\\xD0\\x90\\xD0\\xB4\\xD0\\xB4...'在Traceback中写了这个字符串列名，但我没有列名在我的数据库！ 这是我的models.py：运行命令manage.py migrate错误

编辑 我是从我的数据库中删除所有表并删除所有迁移，之后，一切都精细！
在过去的迁移我添加只有两班，我以前在我的所有类的详细名称，所以问题并不在它 – Vladyslav
也许它在你的2个新类中的一个'verbose_name'字符中。评论那部分了解哪个。 –
刚刚阅读您的更新，好的一切正在工作！ –
