Django

Question

我是 Django 的新手，我遇到了一个问题。我有多个模型需要地址和 phone 数字地址。并且部分机型只能绑定phone个号码。因此，我为“Addresses”和“PhoneNumber”建立了多态关系。喜欢这里：

class PhoneNumber(SoftDeleteModel):
     phone_number = PhoneNumberField()
     content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
     object_id = models.PositiveIntegerField()
     content_object = GenericForeignKey('content_type', 'object_id')
     created_at = models.DateTimeField(auto_now=False, auto_now_add=True)
     updated_at = models.DateTimeField(auto_now=True, auto_now_add=False)
     created_by = models.ForeignKey(get_user_model(), on_delete=models.CASCADE)

     def __str__(self):
         return self.phone_number.as_e164

class Address(SoftDeleteModel):
     house_number = models.CharField(max_length=255)
     street_number = models.CharField(max_length=255)
     area = models.CharField(max_length=255)
     city = models.CharField(max_length=255)
     country = models.CharField(max_length=255)
     content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
     object_id = models.PositiveIntegerField()
     phone_number = GenericRelation(PhoneNumber)
     content_object = GenericForeignKey('content_type', 'object_id')
     created_at = models.DateTimeField(auto_now=False, auto_now_add=True)
     updated_at = models.DateTimeField(auto_now=True, auto_now_add=False)
     created_by = models.ForeignKey(get_user_model(), on_delete=models.CASCADE)

     def __str__(self):
          return str(self.house_number)+", "+str(self.street_number)+", "+self.area+", "+self.city+", "+self.country

这些是 Address 和 PhoneNumber 的模型我在 Address 中使用 [= =28=]供应商喜欢：

class Vendor(SoftDeleteModel):
     vendor_name = models.CharField(max_length=500)
     vendor_phone = GenericRelation(PhoneNumber)
     vendor_address_detailed = GenericRelation(Address)
     vendor_contact_person = models.CharField(max_length=500)
     created_at = models.DateTimeField(auto_now=False, auto_now_add=True)
     updated_at = models.DateTimeField(auto_now=True, auto_now_add=False)
     created_by = models.ForeignKey(get_user_model(), on_delete=models.CASCADE)

     def __str__(self):
          return self.vendor_name

当我在管理员中为供应商制作 crud 时，我只能在地址中获得地址而不是 PhoneNumber 图中的模型

管理员类的代码如下：

class PhoneNumberAdmin(GenericTabularInline):
     model = PhoneNumber
     extra = 1
     exclude = ('deleted', 'created_by')

     def save_model(self, request, obj, form, change):
         obj.created_by = request.user
         super().save_model(request, obj, form, change)


class AddressAdmin(GenericStackedInline):
     model = Address
     extra = 1
     exclude = ('deleted', 'created_by')

     def save_model(self, request, obj, form, change):
         obj.created_by = request.user
         super().save_model(request, obj, form, change)


class VendorAdmin(admin.ModelAdmin):
     model = Vendor
     list_display = ('vendor_name', 'created_by', 'created_at_readable')
     inlines = (AddressAdmin, )
     exclude = ('deleted', 'created_by')

     def created_at_readable(self, obj):
         return naturaltime(obj.created_at)

     created_at_readable.empty_value_display = "???"

请帮助我使用 Django Admin 添加 PhoneNumber。

编辑：

我想将 phone 个数字与每个地址相关联。因此，在管理员中，PhoneNumber 字段将位于 Adress 模型中，而不是 Vendor 中。谢谢

Answer 1

在供应商管理中添加内联电话号码

 inlines = (AddressAdmin, PhoneNumberAdmin)

Answer 2

在网上冲浪后，我发现了这个名为 NestedAdmin 的库。这个库支持管理中几乎所有类型的嵌套关系。我要 post 它的 url 这里。
