目录
获取所有一级目录
视图层Views.py
app/goods/views.py:
from .models import Goods,GoodsCategory
from .filters import GoodsFilter
from .serializers import GoodsSerializer,CategorySerializer
class CategoryViewset(mixins.ListModelMixin, 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
路由urls.py
from goods.views import GoodsListViewSet, CategoryViewset router.register(r'goods',GoodsListViewSet, base_name='goods') #配置category的url router.register(r'categorys', CategoryViewset, base_name="categorys")
效果
http://10.0.0.30:8000/categorys/
获取一级、二级、三级目录
app/goods/serilizers.py 中增加：
CategorySerializer3 代表三级目录，
CategorySerializer2 代表二级目录，
通过各自的sub_cat变量层层嵌套。
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__"

获取某个一级目录的详细信息
Redtful API 获取某个指定对象的详细信息的格式为 GET /zoos/ID
在DRF中 这可以通过CategoryViewset继承mixins.RetrieveModelMixin来实现。
视图层Views.py
app/goods/views.py:
from .models import Goods,GoodsCategory
from .filters import GoodsFilter
from .serializers import GoodsSerializer,CategorySerializer
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
效果验证
http://10.0.0.30:8000/categorys/108/
只返回某个一级目录下的详细信息。
