Question

我是django / python的初学者。我在我的django模型中创建了一个用于存储用户电话号码的字段。我提供了一个正则表达式验证器来验证用户输入的条目，但是当我提交表单时，它会给出多次重复错误。我不确定为什么会出现这个错误。任何帮助表示赞赏。

以下是模型：

class Contact(models.Model):
    account_company_name = models.ForeignKey('Account', on_delete=models.CASCADE, db_column='account_id')
    name = models.CharField(db_column='Contact name', max_length=120, blank=False, null=False)
    email = models.EmailField(primary_key=True, db_column='Email', blank=False, null=False)
    phone = models.CharField(primary_key=True, max_length=10,validators = [RegexValidator(r'\d{10}+|\d{5}([- ]*)\d{6}')],\
        db_column='Phone', blank=False, null=False)
    notes = models.TextField()

    class Meta:
        db_table = 'Contact'

这是forms.py文件：

class ContactForm(forms.ModelForm):
    class Meta:
        model = Contact
        fields = ['account_company_name', 'name', 'email', 'phone', 'notes']

以下是错误跟踪请求：

你的正则表达式无效。我不知道您所需的格式，但可能是您正在寻找的

phone = models.CharField(
    primary_key=True,
    max_length=12,
    validators=RegexValidator(r"^\d{10}|(\d{5}[\-]\d{6})$")], 
    db_column='Phone',
    blank=False,
    null=False)

提交包含电话号码字段的django表单时出现多次重复错误
