Django REST framework数据展示技巧：分页、过滤与搜索的实用配置与实践

from rest_framework.pagination import PageNumberPagination, LimitOffsetPagination
from rest_framework.filters import SearchFilter, OrderingFilter
from django_filters.rest_framework import DjangoFilterBackend
from rest_framework import generics
 
# 定义模型查询集
queryset = YourModel.objects.all()
 
# 序列化器
class YourSerializer(serializers.ModelSerializer):
    class Meta:
        model = YourModel
        fields = '__all__'  # 或者列出所有你想要暴露的字段
 
# 分页配置
class StandardResultsSetPagination(PageNumberPagination):
    page_size = 100
    page_size_query_param = 'page_size'
    max_page_size = 1000
 
# 视图
class YourListView(generics.ListAPIView):
    queryset = YourModel.objects.all()
    serializer_class = YourSerializer
    pagination_class = StandardResultsSetPagination
    filter_backends = [DjangoFilterBackend, SearchFilter, OrderingFilter]
    filterset_fields = ['field1', 'field2']
    search_fields = ['field1', 'field2']
    ordering_fields = ['field1', 'field2']

这个代码实例展示了如何在Django REST framework中配置分页、过滤和搜索功能。首先定义了一个自定义的分页类StandardResultsSetPagination，设置了每页的大小和查询参数。在视图YourListView中，我们使用了分页类，并添加了过滤、搜索和排序功能的后端配置。这些配置可以根据实际模型和需求进行调整。
