python-2.7 - Django Meta Class - 将排序应用于用户的模型字段

Question

我是 Django 1.9 的新手，我有一个 models.py :

class MyProfile(models.Model):

    user = models.OneToOneField(User, on_delete=models.CASCADE)
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    Role = ArrayField(models.CharField(max_length=1000), blank=True,null=True)
    ContactNumber = models.CharField(max_length=100)

    class Meta:
        ordering = ('date_joined',)

在这里我想使用 date_joined 订购表格这是User model的字段.

当我尝试运行时 python manage.py makemigrations它给了我如下错误:

SystemCheckError: System check identified some issues:

ERRORS:
projectmanagement.UniservedTeam: (models.E015) 'ordering' refers to the non-existent field 'date_joined'.

我如何实现这一目标？

要在通用 api View 上设置排序:

http://www.django-rest-framework.org/api-guide/filtering/#orderingfilter

使用:ordering = ('user__date_joined', )
编辑:

您可以像这样在元类上指定排序:

class Meta:
    ordering = ('user__date_joined', )
