Question

我正在尝试验证模特卖家的mobileno（独特）。但它给了我错误而没有做任何期望的任务我该怎么做才能在表格中检查mobileno的唯一性？
以下是我的model.py:

    class Seller(models.Model):
    mobilenno = models.DecimalField(max_digits=10, decimal_places=0, unique=True)  # Field name made lowercase.
    password = models.CharField(max_length=64)
    name = models.CharField( max_length=64)
  #  city = models.ForeignKey(City)
    address = models.CharField(max_length=512, blank=True, null=True)  # Field name made lowercase.
    phoneno = models.DecimalField(max_digits=10, decimal_places=0, blank=True, null=True)  # Field name made lowercase.

和form.py

class SellerRegistrationForm(forms.Form):

    mobileno1 = forms.DecimalField(widget=forms.TextInput(attrs=dict(required=True, max_length=30)),
                                  max_digits=10, decimal_places=0,label=_("Mobile Number"))
    password1 = forms.CharField(widget=forms.PasswordInput(attrs=dict(required=True, max_length=30, render_value=False)),
                                label=_("Password"))
    password2 = forms.CharField(widget=forms.PasswordInput(attrs=dict(required=True, max_length=30, render_value=False)),
                                label=_("Password (again)"))
    name = forms.CharField(widget=forms.TextInput(attrs=dict(required=True, max_length=30)),
                                 label=_("Seller Name"))
    address = forms.CharField(widget=forms.TextInput(attrs=dict(required=True, max_length=30)),
                                 label=_("Seller Address"))
    phoneno = forms.DecimalField(widget=forms.TextInput(attrs=dict(required=True, max_length=30)),
                                 max_digits=10, decimal_places=0, label=_("Phone Number"))

    def clean_mobileno1(self):

        try:
            Seller.objects.get(mobileno=self.cleaned_data['mobileno1'])
        except Seller.DoesNotExist:
            return self.cleaned_data['mobileno1']
        raise forms.ValidationError(_("The mobilenumber already exists. Please try another one."))

    def clean(self):
        if 'password1' in self.cleaned_data and 'password2' in self.cleaned_data:
            if self.cleaned_data['password1'] != self.cleaned_data['password2']:
                raise forms.ValidationError(_("The two password fields did not match."))
        return self.cleaned_data

views.py

def seller_register(request):
    if request.method == 'POST':
        form = SellerRegistrationForm(request.POST)
        if form.is_valid():
            Seller.objects.create(
                mobilenno=form.cleaned_data['mobileno1'],
                password=form.cleaned_data['password1'],
                name=form.cleaned_data['name'],
                address=form.cleaned_data['address'],
                phoneno=form.cleaned_data['phoneno']
            )
            return HttpResponseRedirect('/register/success/')
    else:
        form = SellerRegistrationForm()

    return render(request,'registration/register.html', {'form': form })

我不清楚你得到了什么错误，所以我不确定错误在哪里，但clean_mobileno1看起来是个好人选。检查mobilenno和mobileno1之间的命名一致性。

该函数中的逻辑难以理解，您尝试捕获＆＃34; normal＆＃34;的异常。用例，如果你没有抓住第一个，那么就引发异常，这似乎是反直觉的。此外，您正在检查python中的unicity，当它真的应该被推送到数据库时（字段定义中的unique=True应该强制执行）。

我建议您使用https://github.com/stefanfoulis/django-phonenumber-field代替Decimal电话号码。您将获得实际的电话号码验证，以及一系列非常有用的电话特定功能。后端基于Android的电话号码库，因此它可以保持最新状态。

您的模型变为：

from phonenumber_field.modelfields import PhoneNumberField

class Seller(models.Model):
    mobileno = PhoneNumberField(unique=True)
    ...

此外，您应该使用ModelForm表单：

class SellerRegistrationForm(forms.ModelForm):
    class Meta:
        model = Seller

    ...
