上面哪些我都没试过1，有空再试试看

--------上面全局设置的我没成功----下面的我成功了

view

from django_filters.rest_framework import DjangoFilterBackend
from rest_framework import filters
class BookView(ModelViewSet):
    queryset = Member.objects.all()
    serializer_class = BookSerializers
    filter_backends = (filters.SearchFilter,DjangoFilterBackend,filters.OrderingFilter,)  # 指定过滤器
    search_fields = ('name','sex',)  # 搜索的字段 ?search=123  注意单个字段 要加个,
    filterset_fields = ('name',) #指定可搜索的字段 ?name=123
    ordering_fields = ("id",) #?ordering=-id

模糊查询见 : https://www.cnblogs.com/elijah-li/p/16128524.html （成功了）

view

//自定义过滤
from rest_framework.filters import BaseFilterBackend
from django.db.models import Q


class Myfilter(BaseFilterBackend):
    def filter_queryset(self, request, queryset, view):
        # 获取过滤参数
        qs_name = request.query_params.get('name')
        qs_price = request.query_params.get('price')
        # title__contains：精确大小写查询，SQL中-->like BINARY
        # 利用Q查询构造或关系
        if qs_name:
            queryset = queryset.filter(name__contains=qs_name)
        elif qs_price:
            queryset = queryset.filter(price__contains=qs_price)
        elif qs_name or qs_price:
            queryset = queryset.filter(Q(name__contains=qs_name) | Q(price__contains=qs_price))
        return queryset
    
    
    
 //视图类  
from app01.filter import Myfilter


class BookViewSet(ViewSetMixin, ListAPIView):
    queryset = models.Book.objects
    serializer_class = BookModelSerializer
    authentication_classes = [LoginAuth, ]
    filter_backends = [Myfilter, ]    #指定过滤器
    filterset_fields = ('name',)  # 指定可搜索的字段 ?name=123
