django自带后台页面，也提供了自定义页面的方法。
但有时我们并不满足与django自己的页面，也不想全面码一张新页面然后费力的实现一些功能，我们的目的可能只是想要在自带页面上添加一些自定义按钮，表单等等
django的强大的功能自然允许你这样做

1.templates下cexport_refund_to_oss.html

<div>
    <form action="/cexport_refund_to_oss_Plugin/" method="post">
         <span style="height: 30px;width: 180px;font-size: 15px">
             时间区间：<input type="date" name="StrTime"/>
                                        ---
                       <input type="date" name="EndTime"/>
             &nbsp;&nbsp;
             <input type="submit" name="cex_btn" value="导出CSV"/>
             &nbsp;&nbsp;
            <select name="refund" onchange="window.open(this.options[this.selectedIndex].value,target='_blank')" style="color: blue">
                {% for upurl in URL %}
                    <option value="{{ upurl }}">
                        Download --> <a href="{{ upurl }}" >{{ upurl }}</a>
                    </option>  <br/>
                {% endfor %}
            </select>
        </span>
    </form>
</div>
<br/>

4.xadmin下

xadmin.site.register_plugin(cexport_refund_to_oss_Plugin, ListAdminView)

5.plugin下

from xadmin.views import BaseAdminPlugin
from django.template import loader
from brick.function.find_oss_file import *
import oss2

ossinfo = {'ACCESS_KEY_ID': '', 'ACCESS_KEY_SECRET': '', 'ENDPOINT_OUT': '', '': ''}

class cexport_refund_to_oss_Plugin(BaseAdminPlugin):
	#初设False
    cexport_oss = False

    def init_request(self, *args, **kwargs):
        return bool(self.cexport_oss)

    def get_media(self, media):
        media.add_js([self.static('xadmin/js/xadmin.plugin.button.color.js')])
        return media


    def block_search_cata_nav(self, context, nodes):
        URL = ''
        find_oss_file_obj = find_oss_file()
        result = find_oss_file_obj.findfile(ossinfo=ossinfo, timerange=86400000*3,urlload='refund')
        if result['errorcode'] == 0:
            URL = result['fileurl']
        nodes.append(loader.render_to_string('cexport_refund_to_oss.html', {'URL':URL}))

6.admin下

 cexport_oss = True
