在我的模型中。py，有两种模型，AvailableArea有一个外域，请参阅AddressRegion：

class AddressRegion(models.Model):
    name = models.CharField(max_length=8)
    def __str__(self):
        return self.name
    def __unicode__(self):
        return self.name
class AvailableArea(models.Model):
    name = models.CharField(max_length=8)
    addressregion = models.ForeignKey(AddressRegion, default=1, related_name='availableareas', on_delete=models.CASCADE)
    def __str__(self):
        return self.name
    def __unicode__(self):
        return self.name

在序列化程序中。py，我序列化所有字段：

class AvailableAreaSerializer(ModelSerializer):
    """
    region
    """
    class Meta:
        model = AvailableArea
        fields = "__all__"

在views.py中：

class AddressRegionListAPIView(ListAPIView):
    serializer_class = AddressRegionSerializer
    permission_classes = []
    queryset = AddressRegion.objects.all()

其余框架数据如下：

[
    {
        "id": 13,
        "name": "st-01",
        "addressregion": 3
    },
    {
        "id": 14,
        "name": "tg-02",
        "addressregion": 4
    },
    {
        "id": 15,
        "name": "sx-01",
        "addressregion": 3
    }
]

我希望addressregion不显示addressregion的id，而是显示addressregion的m2n4o1p。
