问题描述
如果我使用 Facebook 帐户登录，当我尝试更新我的用户个人资料时出现错误（'nonetype' 对象没有属性 'city_set'）。我假设问题是由以下原因引起的：最初没有选择国家和城市。正常注册和更新用户个人资料没有问题，但是social_django违反了规则。我正在使用 abstractbaseuser 模型，并且它有一个国家-城市模型。我尝试了很多方法来解决这个问题，但这些都没有帮助。非常感谢您提前抽出时间...

解决方法
在您的 AccountUpdate 表单中，您写了：
// Set graduationDate to enrollmentDate,then add 4 years
graduationDate = new GregorianCalendar(); // New object
graduationDate.setTime(enrollmentDate.getTime()); // Update time
graduationDate.add(GregorianCalendar.YEAR,4); // add years
但用户可能没有国家/地区，因此将其更改为：
elif self.instance.pk:
self.fields['city'].queryset = self.instance.country.city_set.order_by('name')
