Python+Flask实现自定义分页的示例代码

def Pagination(page_num,totals):
    ret = {"prev_page": page_num - 1,  # 上一页
           "next_page": page_num + 1,  # 下一页
           "current_page": 0,          # 当前页
           "total_pages": 0,           # 总页数
           "max_page": 0,              # 最大页
           "page_size": app.config["PAGE_SIZE"],  # 每页的数据，放在配置中方便更改
           "totals": totals,           # 数据总条数
           "offset": 0,                # 偏移量
           "page_range": None          # 页码范围
           }

    ret["total_pages"] = math.ceil(totals / ret["page_size"])

        page_num = 1

        page_num = ret["max_page"]
        ret["next_page"] = ret["max_page"]

    ret["current_page"] = page_num

    if totals == 0:
        ret["offset"] = 0

    page_range = []
    for i in range(1,ret["max_page"]+1):
        page_range.append(i)
