流程

在goods文件夹下filters.py的代码以下：

filters.py

import django_filters
from django.db.models import Q

from .models import Goods


class GoodsFilter(django_filters.rest_framework.FilterSet):
    """ 商品的过滤类 """
    pricemin = django_filters.NumberFilter(name='shop_price', help_text="最低价格",lookup_expr='gte')
    pricemax = django_filters.NumberFilter(name='shop_price', lookup_expr='lte')
    top_category = django_filters.NumberFilter(method='top_category_filter')


    def top_category_filter(self, queryset, name, value):
        return queryset.filter(Q(category_id=value)|Q(category__parent_category_id=value)|Q(category__parent_category__parent_category_id=value))


    class Meta:
        model = Goods
        fields = ['pricemin', 'pricemax']

goods文件夹下serializers.py代码以下：

serializers.py

from rest_framework import serializers
from django.db.models import Q

from goods.models import Goods, GoodsCategory,HotSearchWords,GoodsImage,Banner,GoodsCategoryBrand

class CategorySerializer3(serializers.ModelSerializer):
    class Meta:
        model = GoodsCategory
        fields = "__all__"


class CategorySerializer2(serializers.ModelSerializer):
    sub_cat = CategorySerializer3(many=True)
    class Meta:
        model = GoodsCategory
        fields = "__all__"


class CategorySerializer(serializers.ModelSerializer):
    sub_cat = CategorySerializer2(many=True)
    class Meta:
        model = GoodsCategory
        fields = "__all__"


class GoodsImageSerializer(serializers.ModelSerializer):
    class Meta:
        model = GoodsImage
        fields = ("image", )

class GoodsSerializer(serializers.ModelSerializer):
    category = CategorySerializer()
    images = GoodsImageSerializer(many=True)
    class Meta:
        model = Goods
        fields = "__all__"

class GoodCategorySerializer(serializers.ModelSerializer):
    ''' 商品类别序列化 '''
    class Meta:
        model = Goods
        fields = "__all__"

class HotWordsSerializer(serializers.ModelSerializer):
    class Meta:
        model = HotSearchWords
        fields = "__all__"


class BannerSerializer(serializers.ModelSerializer):
    class Meta:
        model = Banner
        fields = "__all__"


class BrandSerializer(serializers.ModelSerializer):
    class Meta:
        model = GoodsCategoryBrand
        fields = "__all__"

goods文件夹下views.py代码以下：

views.py

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import mixins
from rest_framework import generics
from rest_framework import filters
from rest_framework.pagination import PageNumberPagination
from django_filters.rest_framework import DjangoFilterBackend
from rest_framework import viewsets
from rest_framework.authentication import TokenAuthentication

from .models import Goods,GoodsCategory,HotSearchWords
from .serializers import GoodsSerializer,CategorySerializer,HotWordsSerializer
from .filters import GoodsFilter
# Create your views here.

class GoodsPagination(PageNumberPagination):
    page_size = 12
    page_size_query_param = 'page_size'
    page_query_param = "page"
    max_page_size = 100

class GoodsListViewSet(mixins.ListModelMixin, mixins.RetrieveModelMixin, viewsets.GenericViewSet):
    """ 商品列表页, 分页， 搜索， 过滤， 排序 """
    queryset = Goods.objects.all()
    serializer_class = GoodsSerializer
    pagination_class = GoodsPagination
    # authentication_classes = (TokenAuthentication, )
    filter_backends = (DjangoFilterBackend, filters.SearchFilter, filters.OrderingFilter)
    filter_class = GoodsFilter
    search_fields = ('name', 'goods_brief', 'goods_desc')
    ordering_fields = ('sold_num', 'add_time')


class CategoryViewset(mixins.ListModelMixin, mixins.RetrieveModelMixin, viewsets.GenericViewSet):
    """ list: 商品分类列表数据 retrieve: 获取商品分类详情 """
    queryset = GoodsCategory.objects.filter(category_type=1)
    serializer_class = CategorySerializer


class HotSearchsViewset(mixins.ListModelMixin, viewsets.GenericViewSet):
    """ 获取热搜词列表 """
    queryset = HotSearchWords.objects.all().order_by("-index")
    serializer_class = HotWordsSerializer

修改api.js文件中商品详情ip

后台测试发现正常返回数据

查看商品详情页信息，正常显示

若添加商品为热销，须要在xadmin后台管理中添加
