[django]数据导出excel升级强化版(很强大!)

Posted 2020-08-01 CQ_LQJ

不多说了,原理采用xlwt导出excel文件,所谓的强化版指的是实现在网页上选择一定条件导出对应的数据

之前我的博文出过这类文章,但只是实现导出数据,这次左思右想,再加上网上的搜索,终于找出方法实现条件导出的功能了.

先上图:

再说明:核心是使用django视图中的命名组,例如配置url(r\'^perm=(?P<a>\\w+)$\', \'keywork.views.work)

          那么,我可以访问网址/perm=参数值,这类的参数值就是我们的条件了,最后在javascript中编写一个click函数弹出对应的链接即可

后代码:

模板中html代码:

       <div class="tab-pane" id="data_export"><!-- 标签页--4--数据导出 -->
            <h4>导出条件选项</h4>
            <form class="form-inline">

                    <option value="{{a.day_id}}">{{a.day_id}}</option>
