04.PageNumberPagination分页

一.使用默认分页

1.settings 设置

REST_FRAMEWORK = {

    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',

    'PAGE_SIZE': 2

}

2.参数

1.第几页

    # Client can control the page using this query parameter.

    page_query_param = 'page'

    page_query_description = _('A page number within the paginated result set.')

2.每页大小

    # Client can control the page size using this query parameter.

    # Default is 'None'. Set to eg 'page_size' to enable usage.

    page_size_query_param = None

    page_size_query_description = _('Number of results to return per page.')

3.最大页

    # Set to an integer to limit the maximum page size the client may request.

    # Only relevant if 'page_size_query_param' has also been set.

    max_page_size = None

二.自定义分页

avue 前端分页参数：

# 前端很喜欢用 data，把 result 改成 data

{ "total": 40, "pagerCount": 5, "currentPage": 1, "pageSize": 20, "pageSizes": [ 10, 20, 30, 40, 50, 100 ], "background": true }

from rest_framework.pagination import PageNumberPagination

from rest_framework.response import Response

from collections import OrderedDict, namedtuple

class LargeResultsSetPagination(PageNumberPagination):

    page_query_param = 'pagerCount'

    page_query_description = '当前第几页'

    page_size = 20

    page_size_query_param = 'pageSize'

    page_size_query_description = '每页条目数'

    max_page_size = 100

    def get_paginated_response(self, data):

        return Response(OrderedDict([

            ('total', self.page.paginator.count),

            ('next', self.get_next_link()),

            ('previous', self.get_previous_link()),

            ('data', data)

        ]))

# settings

REST_FRAMEWORK = {

    # 指定用于支持coreapi的Schema

    'DEFAULT_SCHEMA_CLASS': 'rest_framework.schemas.coreapi.AutoSchema',

    'DEFAULT_PAGINATION_CLASS': 'utils.utils.LargeResultsSetPagination',

    'PAGE_SIZE': 10,

}

结果如下

{

    "total": 104,

    "next": "http://127.0.0.1:8000/idcs/?pageSize=1&pagerCount=5",

    "previous": "http://127.0.0.1:8000/idcs/?pageSize=1&pagerCount=3",

    "data": [

        {

            "id": 4,

            "name": "华为机房0",

            "address": "神州路0号大院",

            "phone": "13412345678",

            "email": "mail_0@com.cn",

            "letter": "hw0"

        }

    ]

}

如果某个视图不需要分页，视图设置分页类为 None 即可

pagination_class = None
