Django REST framework 分页实战

前言

rest framework中提供了三种分页模式：

from rest_framework.pagination import 
PageNumberPagination, LimitOffsetPagination, CursorPagination

在我的项目中我使用的是PageNumberPagination
在全局配置文件，在用到的使用才会引入，有点像配置文件

REST_FRAMEWORK = {
    
    'rest_framework.pagination.PageNumberPagination',
    'PAGE_SIZE':20,
    
}

去实现

?

1 2 3 4 5 6 7 8 9 10 11 12

class text_list(APIView):     """     get: 获取列表页     """     def get(self, request):         coin_model=models.objects.all().order_by("-id")         //使用继承的方式实现分页对象         pg = MyPageNumberPagination()         objs = pg.paginate_queryset(coin_model, request,self)         ser = serializers.Serializer(objs, many=True)         data=pg.get_response_data(ser.data, 'list')         return response_util.ok(data=data)

class MyPageNumberPagination(PageNumberPagination):
    page_size = 6
    max_page_size = 100
    page_size_query_param = 'page_size'
    page_query_param = 'page_index'
​
    def get_response_data(self, data, data_key='results', **kwargs):
        data = {
            'page_total': self.page.paginator.count,
            'page_index': self.page.number,
            'page_size': len(data),
            data_key: data
        }
        data.update(**kwargs)
        return data

from rest_framework import serializers
​
from . import models
​
class Serializer(serializers.ModelSerializer):
    class Meta:
        model = models.TokenTpl
        fields = [
        //序列化的字段，也就是要输出的字段
            'id','name'
        ]
