获取一级目录

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, 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

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__"
