DRF之过滤与排序

过滤组件

基于django内置的过滤组

from django_filters.rest_framework import DjangoFilterBackend
from rest_framework.generics import ListAPIView
需继承generics

class BooksGenericListApiView(ListAPIView):
    authentication_classes = []
    queryset = models.Book.objects.all()
    serializer_class = BookModelSerializer
    filter_backends = [DjangoFilterBackend]
　　定义过滤器

    filterset_fields=['title','addr']
　　定义过滤方式和字段 这个只能写models内有的字段，不能写方法

排序组件

这个需要借用django_filter   pip install 即可

from django_filters.rest_framework import DjangoFilterBackend
from rest_framework.filters import OrderingFilter
from rest_framework.generics import ListAPIView
class BooksGenericListApiView(ListAPIView):
    authentication_classes = []
    queryset = models.Book.objects.all()
    serializer_class = BookModelSerializer
    filter_backends = [DjangoFilterBackend,OrderingFilter]
    filterset_fields=['title','addr']

    ordering_fields=['price','id']

　　ordering_param = 'sort'
　　这个属性不好使
