如何将电话号码字段添加到 django UserCreationForm？答案

【问题描述】：

我想添加 PhoneNumberField 以便在注册时使用用户的电话号码。我已经有 CreateUserForm 用来创建新用户的 UserCreationForm 模型。但是默认情况下它没有电话号码字段。我尝试通过在 forms.py 中添加 phone 变量来添加它，但它不起作用并给出以下错误。

forms.py

class CreateUserForm(UserCreationForm):
    phone=PhoneNumberField()
    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2', 'phone']

models.py

class CustomerReg(models.Model):
    user=models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE)
    name=models.CharField(max_length=200, null=True)
    email=models.EmailField(max_length=254)
    phone=PhoneNumberField(default=None)
def create_profile(sender, **kwargs):
    if kwargs['created']:
        user_profile=CustomerReg.objects.create(user=kwargs['instance'])

post_save.connect(create_profile, sender=User)

这是我在运行 python manage.py makemigrations 时遇到的错误

【解决方案1】：

我建议这样做：

from django.core.validators import RegexValidator

class CreateUserForm(UserCreationForm):
   phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
   phone = forms.CharField(validators=[phone_regex], max_length=17)
   class Meta:
      model = User
      fields = ['username', 'email', 'password1', 'password2', 'phone']
