Answer 1

謝謝你的回答我已經通過你的回答改變了一些代碼它正在工作非常感謝你兄弟

模型.py

date_of_birth = models.DateField(null=True)
pin_code = models.IntegerField(null=True)

表格.py

def save(self, commit=True):
        user = super().save(commit=False)
        user.set_password(self.cleaned_data['password1'])
        if commit:
            user.save()
        return user
