Django PhoneNumberField-不保存电话号码'；s扩展

在django应用程序中，我使用PhoneNumberFields modelfields和formfields。在表格中输入电话号码（例如+15146661234x99）时，分机（即99）不会保存在型号中。我做错了什么？ 以下是我的代码摘录：

型号.py

from phonenumber_field.modelfields import PhoneNumberField

class Profile(models.Model):
    user = models.OneToOneField(User, null=True, on_delete=models.CASCADE)
    phone = PhoneNumberField(_('Telephone'), max_length=30, null=True, blank=True, unique=False)

def userUpdate(request, pk):
    template = 'plans/form_user.html'
    context = {}
    user = User.objects.get(pk=pk)
    profile = user.profile
    form = ProfileForm(request=request, instance=profile)
    if request.method == 'POST':
        form = ProfileForm(request.POST, request=request, instance=profile)
        if form.is_valid():
            form.save()
            messages.success(request, _("Information of administrator {} has been updated").format(user))
            context['message_tag'] = 'success'
            return redirect('user_list')

    context['user'] = user
    context['form'] = form
    return render(request, template, context) 

from phonenumber_field.formfields import PhoneNumberField

class ProfileForm(ModelForm):
    class Meta:
        model = Profile
        fields = ['phone',]

    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop('request')
        super().__init__(*args, **kwargs)

        self.fields['phone'] = PhoneNumberField(
            label=_('Telephone number'),
            help_text=_('Enter a valid phone number, e.g. +14185551234x22')
            )

视图.py

from phonenumber_field.modelfields import PhoneNumberField

class Profile(models.Model):
    user = models.OneToOneField(User, null=True, on_delete=models.CASCADE)
    phone = PhoneNumberField(_('Telephone'), max_length=30, null=True, blank=True, unique=False)

def userUpdate(request, pk):
    template = 'plans/form_user.html'
    context = {}
    user = User.objects.get(pk=pk)
    profile = user.profile
    form = ProfileForm(request=request, instance=profile)
    if request.method == 'POST':
        form = ProfileForm(request.POST, request=request, instance=profile)
        if form.is_valid():
            form.save()
            messages.success(request, _("Information of administrator {} has been updated").format(user))
            context['message_tag'] = 'success'
            return redirect('user_list')

    context['user'] = user
    context['form'] = form
    return render(request, template, context) 

from phonenumber_field.formfields import PhoneNumberField

class ProfileForm(ModelForm):
    class Meta:
        model = Profile
        fields = ['phone',]

    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop('request')
        super().__init__(*args, **kwargs)

        self.fields['phone'] = PhoneNumberField(
            label=_('Telephone number'),
            help_text=_('Enter a valid phone number, e.g. +14185551234x22')
            )

forms.py

from phonenumber_field.modelfields import PhoneNumberField

class Profile(models.Model):
    user = models.OneToOneField(User, null=True, on_delete=models.CASCADE)
    phone = PhoneNumberField(_('Telephone'), max_length=30, null=True, blank=True, unique=False)

def userUpdate(request, pk):
    template = 'plans/form_user.html'
    context = {}
    user = User.objects.get(pk=pk)
    profile = user.profile
    form = ProfileForm(request=request, instance=profile)
    if request.method == 'POST':
        form = ProfileForm(request.POST, request=request, instance=profile)
        if form.is_valid():
            form.save()
            messages.success(request, _("Information of administrator {} has been updated").format(user))
            context['message_tag'] = 'success'
            return redirect('user_list')

    context['user'] = user
    context['form'] = form
    return render(request, template, context) 

from phonenumber_field.formfields import PhoneNumberField

class ProfileForm(ModelForm):
    class Meta:
        model = Profile
        fields = ['phone',]

    def __init__(self, *args, **kwargs):

        super().__init__(*args, **kwargs)

        self.fields['phone'] = PhoneNumberField(

            help_text=_('Enter a valid phone number, e.g. +14185551234x22')
