我正在尝试为模型创建一个表单，该表单继承自 Django auth.User 类

我得到了这个问题。有没有更好的方法来实现它？

#models.py

class Teacher(User):
    #tutor = models.OneToOneField(User, on_delete=models.CASCADE, parent_link=True)
    department = models.CharField(max_length=100)
    contact_no = models.BigIntegerField()

    def __str__(self):
        return "%s %s" % (self.tutor.first_name, self.tutor.last_name)

#Forms.py
class TeacherForm(forms.ModelForm):
    class Meta:
        model = Teacher
        fields = ('username', 'first_name', 'last_name', 'email', 'contact_no', 'department')

#views.py
def new_teacher(request):
    form = TeacherForm()
    return render(request, {'form': form})

Django 版本：2.2.3
异常类型：TypeError

异常值：
join() 参数必须是 str 或 bytes，而不是 'dict'
