1. 安装django-filter

   pip install django-filter
   

2. 在视图中定义一个FilterSet类，指定要过滤的模型，以及要过滤的字段

   from django_filters import rest_framework as filters
   
   class MyFilterSet(filters.FilterSet):
       name = filters.CharFilter(lookup_expr='icontains')
       age = filters.RangeFilter()
   
       class Meta:
           model = MyModel
           fields = ['name', 'age']
   

3. 将FilterSet类传递给Django视图

   from rest_framework import generics
   
   class MyListView(generics.ListAPIView):
       queryset = MyModel.objects.all()
       serializer_class = MySerializer
       filter_backends = [filters.DjangoFilterBackend]
       filterset_class = MyFilterSet
   

4. 在URLconf中定义相应的url

   from django.urls import path
   from .views import MyListView
   
   urlpatterns = [
       path('my-list/', MyListView.as_view()),
   ]
   

现在，当向 my-list/ 发出请求时，只有与 name 字段匹配的记录和年龄字段范围匹配的记录会被返回。
