如同Django提供了Form类和ModelForm类一样，REST framework包括Serializer类和ModelSerializer类.
from rest_framework import serializers
from goods.models import Goods
class GoodsSerializer(serializers.ModelSerializer):
class Meta:
model = Goods
# fields = ("name","sold_num","fav_num","price")
fields = "__all__"
上述代码还存在一个问题，由于category字段是Category表的外键，因此此处我们显示的结果仅仅是Category表中的id,而不是该表的所有字段
解决方法：
class CategorySerializer(serializers.ModelSerializer):
class Meta:
model = GoodsCategory
fields = "__all__"
class GoodsSerializer(serializers.ModelSerializer):
category = CategorySerializer()
class Meta:
model = Goods
# fields = ("name","sold_num","fav_num","price")
fields = "__all__"
如果应用于多对多关系，则应将此参数设置为True,category = CategorySerializer(many=True)
