Question

当我尝试使用页面中的UserChangeForm修改当前条目时，显示“用户已存在”。但是我没有问题，可以通过管理门户修改条目。

model.py

class User(AbstractUser):
    users = (
        ('doctor', 'Doctor'),
        ('patient', 'Patient'),
        ('assistant', 'Assistant'),
    )

    user_type = models.CharField(choices=users, max_length=9, default='patient')

    #return the users' name
    def __str__(self):
        return self.first_name  + " " + self.last_name

class Doctor(models.Model):
    upin = models.AutoField(primary_key=True) #unique physician identification number
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    user.user_type = "doctor"
    specialty = models.CharField(max_length=20)
    appointments_per_hour = models.IntegerField(null=True)

    #return the doctors' name
    def __str__(self):
        return str(self.user)

forms.py

class DoctorForm(UserChangeForm):
    class Meta:
        model = Doctor
        fields = ('user','specialty','appointments_per_hour',)

Django-如何在网络应用中使用UserChangeForm？
