1、Django原生分页代码

原生分页

# 分页

def page(num, size = 10):

    # 接收当前页码数

    num = int(num)


    # 总记录数

    totalRecords = models.ReservoirData.objects.count()

    # 总页数

    totalPages = int(math.ceil(totalRecords*1.0/size))   # math.ceil() 向上取整 1.2 --> 2.0


    # 判断是否越界

    if num < 1:

        num = 1

    if num > totalPages:

        num = totalPages


    # 计算每页显示的记录

    reservoirs = models.ReservoirData.objects.all()[((num-1)*size): (num*size)]


return reservoirs, num
