python - 电子邮件验证(1062， "Duplicate entry ''对于 key 'email'“)

Question

我在注册时有两个电子邮件字段，用于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.")

当我尝试保存模型时，出现错误:

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

如果您还需要什么，请告诉我

您应该重写 save() 方法并在其中设置用户的 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
