如何在django restframework中过滤许多字段值

from django_filters.rest_framework import DjangoFilterBackend
from rest_framework import filters
from .models import YourModel

import django_filters

class YourModelFilter(django_filters.FilterSet):
    field1 = django_filters.CharFilter(lookup_expr='icontains')
    field2 = django_filters.NumberFilter(lookup_expr='exact')
    # 添加更多的字段过滤器

    class Meta:
        model = YourModel
        fields = ['field1', 'field2']  # 根据你的需求添加更多的字段

from rest_framework import generics

class YourModelListView(generics.ListAPIView):
    queryset = YourModel.objects.all()
    serializer_class = YourModelSerializer
    filter_backends = [DjangoFilterBackend, filters.SearchFilter, filters.OrderingFilter]
    filterset_class = YourModelFilter
    search_fields = ['field1', 'field2']  # 根据你的需求添加更多的搜索字段
    ordering_fields = ['field1', 'field2']  # 根据你的需求添加更多的排序字段
