• views.py

from rest_framework import generics

from . import models
from .serializers import GoodsSerializer


class GoodsList(generics.ListCreateAPIView):

    """
    List all goods, or create a new good.
    """

    queryset = models.Goods.objects.all()
    serializer_class = GoodsSerializer


class GoodsDetail(generics.RetrieveUpdateDestroyAPIView):
    """
    List one good, update the good or delete the good.
    """

    queryset = models.Goods.objects.all()
    serializer_class = GoodsSerializer

• serializers.py

from rest_framework import serializers
from . import models

class CategorySerializer(serializers.ModelSerializer):

    class Meta:
        model = models.GoodsCategory
        fields = "__all__"

class GoodsSerializer(serializers.ModelSerializer):

    # 重写外键，序列化输出
    category = CategorySerializer()
    class Meta:
        model = models.Goods
        fields = "__all__"

• urls.py

from . import views
from django.urls import path
from rest_framework.urlpatterns import format_suffix_patterns

urlpatterns = [
    path('goods/',views.GoodsList.as_view(),name='goods_list'),
    path('goods/<int:pk>/', views.GoodsDetail.as_view()),
]

urlpatterns = format_suffix_patterns(urlpatterns)
