【问题描述】：

我正在创建一个带有电话号码字段的 django 模型表单。我已经 pip 安装了 phonenumber 字段模块并将其添加到我已安装的应用程序中，但现在当我尝试运行迁移以将此字段的表单添加到我的数据库中时。我得到这个错误。我做错了什么。

__init__
 if field.is_relation and hasattr(field.related_model, '_meta'):
AttributeError: 'PhoneNumberField' object has no attribute 'is_relation'

这是我的model.py

from django.db import models
from phonenumber_field.formfields import PhoneNumberField

class Profile(models.Model):
 Name = models.CharField(max_length=100)
 Last_Name = models.CharField(max_length=100)
 phone_number = PhoneNumberField()
 Address_Line_1 = models.CharField(max_length=300)
 Address_Line_2 = models.CharField(max_length=300)
 Postcode = models.IntegerField()
 State = models.CharField(max_length=100)
 Area = models.IntegerField()
 Email = models.EmailField()
 Country = models.CharField(max_length=300)
 State_Region = models.CharField(max_length=100)

 def __str__(self):
    return self.Name + ' ' + self.State_Region

forms.py

from .models import Appear, Performance, Profile2, Publicity, Bookings, Profile
from phonenumber_field.formfields import PhoneNumberField

class Profiles(forms.ModelForm):

   phone_number = PhoneNumberField()

   class Meta:
      model = Profile
      fields = "__all__"

【参考方案1】：

您现在可能已经解决了（或放弃了），但以防万一：问题是您将 表单字段 放入模型中，但您需要一个 模型字段。这很令人困惑，它一直在发生。如果您将 models.py 中的导入更改为 from phonenumber_field.modelfields import PhoneNumberField，它应该可以工作。
