Question

我在django应用程序中有两个模型，Doctor和Django Built in User模型。每个人都可以拥有许多注册的电话号码和地址。我决定创建一个地址簿应用程序来存储地址和电话号码。

地址簿应用

models.py

from __future__ import unicode_literals

from django.contrib.contenttypes.models import ContentType
from django.contrib.contenttypes.fields import GenericForeignKey
from django.db import models
from django.db import models
from django.utils.translation import ugettext_lazy as _
from django.db.models import permalink
from django.contrib.auth.models import User
from django.conf import settings
from doctors.models import Doctor
from django.core.validators import RegexValidator


class AddressPhoneType(models.Model):
    type_name = models.CharField(_('Type'), max_length=50)

    class Meta:
        verbose_name = _('Address / Phone Type')
        verbose_name_plural = _('Address / Phone Type')

    def __unicode__(self):
        return u'%s' % self.type_name


class City(models.Model):
    city = models.CharField(_('City'), max_length=50)

    class Meta:
        verbose_name = _('City')
        verbose_name_plural = _('Cities')

    def __unicode__(self):
        return u'%s' % self.city


class Address(models.Model):
    """Address model."""
    body = models.TextField(_('Address'))
    city = models.ForeignKey(City, null=True)
    lng = models.DecimalField(max_digits=9, decimal_places=6)
    lat = models.DecimalField(max_digits=9, decimal_places=6)

    #content_type = models.ForeignKey(ContentType, related_name="content_type_address")
    #object_id = models.PositiveIntegerField()
    #content_object = GenericForeignKey()

    doctor = models.ForeignKey(Doctor, null=True)
    user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True)
    address_type = models.ForeignKey(AddressPhoneType)

    class Meta:
        verbose_name = _('Address')
        verbose_name_plural = _('Addresses')

    def __unicode__(self):
        return u'%s' % self.body


class PhoneNumber(models.Model):
    phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="""Phone number must be entered in the format: 
        '+999999999' or '999999999'. Up to 15 digits allowed.""")
    phone_number = models.CharField(validators=[phone_regex], blank=True, max_length=15)
    description = models.CharField(_('Description'), max_length=100)
    phone_type = models.ForeignKey(AddressPhoneType)
    doctor = models.ForeignKey(Doctor, null=True)
    user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True)

    class Meta:
        verbose_name = _('Phone Number')
        verbose_name_plural = _('Phone Number')

    def __unicode__(self):
        return u'%s - %s' % (self.phone_number, self.description)

如果你看一下类别地址，有两个外键，一个给用户，另一个给医生，所以每个地址条目可以与任何一个相关联（相同的机制适用于手机）。问题是，当我进入管理页面并添加医生（我将地址模型设置为在医生应用程序的admin.py中显示为inine）时，我看到用户下拉以选择该用户的添加地址这似乎不正确。

我尝试使用ContentType和GenericForeignKeys，但我认为它们不是解决方案....有什么建议吗？

我猜您在AddressInline内创建了DoctorAdmin，如果是这种情况，您可以将用户排除在inline之外。

from django.contrib import admin

class AddressInline(admin.TabularInline):
    model = Address
    exclude = ('user',)

class DoctorAdmin(admin.ModelAdmin):
    inlines = [
        AddressInline,
    ]
