在Django REST框架中，如何根据用户过滤列表？

from django_filters.rest_framework import DjangoFilterBackend

class MyFilter(filters.FilterSet):
    # 定义过滤的字段和条件
    field_name = filters.Filter(lookup_expr='exact')  # 精确匹配

    class Meta:
        model = MyModel  # 指定过滤的模型
        fields = ['field_name']  # 指定需要过滤的字段

from django_filters import rest_framework as filters

class MyViewSet(viewsets.ModelViewSet):
    queryset = MyModel.objects.all()
    serializer_class = MySerializer
    filter_backends = [DjangoFilterBackend]
    filterset_class = MyFilter  # 将过滤器类作为参数传递

    # 其他视图逻辑...
