排序

代码：

from rest_framework.generics import ListAPIView
from rest_framework.filters import OrderingFilterclass TestListAPIView(ListAPIView):queryset = models.Course.objects.filter(is_delete=False).all()serializer_class = serializers.TestModelSerializer# 配置过滤器类filter_backends = [OrderingFilter,]# 参与排序的字段: ordering=-score, idordering_fields = ['id', 'score']

前端请求：

http://127.0.0.1:8000/api/test?ordering=-score,id

群查搜索过滤器

代码：

from rest_framework.generics import ListAPIView
# SearchFilter搜索过滤器
from rest_framework.filters import SearchFilterclass TestListAPIView(ListAPIView):queryset = models.Course.objects.filter(is_delete=False).all()serializer_class = serializers.FreeCourseModelSerializer# 配置搜索过滤器类filter_backends = [SearchFilter]# 参与搜索的字段: search = liuliuliu (意思是name、status、create_by字段中带liuliuliu就可以了)search_fields = ['name', 'status', 'create_by']

前端请求：

http://127.0.0.1:8000/api/test?search=liuliuliu

自定义过滤器

自定义过滤器代码：

from rest_framework.filters import BaseFilterBackendclass MyFilter(BaseFilterBackend):def filter_queryset(self, request, queryset, view):# 例如：获取前端想要的数据条数limit = request.query_params.get('limit')try:return queryset[:int(limit)]except:return queryset

视图代码：

from rest_framework.generics import ListAPIView
from rest_framework.filters import OrderingFilterclass TestListAPIView(ListAPIView):queryset = models.Course.objects.filter(is_delete=False).all()serializer_class = serializers.FreeCourseModelSerializer# 配置过滤器类, 自定义过滤器类可与自带的共用filter_backends = [OrderingFilter, MyFilter]  # MyFilter为自定义过滤器# 参与排序的字段: ordering=-score,idordering_fields = ['id', 'score']

前端请求：

http://127.0.0.1:8000/api/test?limit=5
