Python 电子邮件验证（1062，密钥和电子邮件的“重复输入和重复输入”）

我在注册中有两个电子邮件字段来验证电子邮件是否正确：

这是我的表格：

class RegistrationForm(forms.ModelForm):
    email1 = forms.EmailField(label="El.paštas")
    email2 = forms.EmailField(label="Pakartokite el. paštą")

    class Meta:
        model = AuthUser
        fields = ("email1", "email2", "first_name", "last_name", "password", "city", "other_city", "age", "accepts_emails")
        widgets = {
            "password": forms.PasswordInput(),
        }

    def __init__(self, *args, **kwargs):
        super(RegistrationForm, self).__init__(*args, **kwargs)
        self.fields["city"].queryset = City.objects.filter(other_city=False)

        for field_name in self.fields:
            field = self.fields.get(field_name)

            if field and field_name != "accepts_emails" and field_name != "other_city":
                field.widget.attrs.update({"class": "form-control"})

    def clean_email2(self):
        email1 = self.cleaned_data["email1"]
        email2 = self.cleaned_data["email2"]

        if email1 and email2 and email1 != email2:
            raise forms.ValidationError("El. pašto adresai nesutampa.")

        try:
            AuthUser._default_manager.get(email=email1)
        except AuthUser.DoesNotExist:
            return email1

        raise forms.ValidationError("Toks el. paštas jau naudojamas.")

当我试图保存我的模型时，我得到的错误是：

IntegrityError at /registracija/
(1062, "Duplicate entry '' for key 'email'")

如果您还需要其他任何信息，请告知我

您应该覆盖

save（）

方法，并在此处设置用户的

email

字段：

def save(self, *args, **kwargs):
    user = super(RegistrationForm, self).save(commit=False)
    user.email = self.cleaned_data['email1']
    user.save()
    return user

---

“重复输入”错误是因为您在

电子邮件中有唯一的密钥。但是，您的字段是
email1
和
email2
。你迁移了应用程序吗？什么是迁移？我是指你的应用程序的南迁移，以便更新数据库中的模型AuthUser。你的
AuthUser
模型是什么？
