丝路通：apiview方式实现商品列表页2

序列化serializers.py

cd /root/mxshop/apps/goods

基于DRF ,编写serializers 序列化功能

vi serializers.py

__author__ = 'bobby'

from rest_framework import serializers

from goods.models import Goods

class GoodsSerializer(serializers.ModelSerializer):

    class Meta:
        model = Goods
        fields = "__all__"

视图层views.py

vi /root/mxshop/apps/goods/views.py

from .serializers import GoodsSerializer
from rest_framework.views import APIView
from rest_framework.response import Response


from .models import Goods

# Create your views here.

class GoodsListView(APIView):
    """
    商品列表页
    """


    def get(self, request):
        goods =Goods.objects.all()[:10]
        goods_serializer = GoodsSerializer(goods,many=True)
        return Response(goods_serializer.data)

路由urls.py

from django.conf.urls import url, include
#from django.contrib import admin
import xadmin
from mxshop.settings import MEDIA_ROOT
from django.views.static import serve
from rest_framework.documentation import include_docs_urls

from goods.views import GoodsListView
urlpatterns = [
    url(r'^xadmin/', xadmin.site.urls),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
    url(r'^media/(?P<path>.*)$', serve, {"document_root": MEDIA_ROOT}),
    url(r'goods/$',GoodsListView.as_view(), name="goods-list"),
    url(r'docs/', include_docs_urls(title="silutong")),

]

测试

在浏览器输入：http://10.0.0.30:8000/goods/

上图中 图片位置的补全，是DRF 根据settings.py中MEDIA_URL参数自动配置的结果。

另外，按下Option按钮，会显示：

HTTP 200 OK
Allow: GET, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept

{
    "name": "Goods List",
    "description": "商品列表页",
    "renders": [
        "application/json",
        "text/html"
    ],
    "parses": [
        "application/json",
        "application/x-www-form-urlencoded",
        "multipart/form-data"
    ]
}
