import xadmin
 
from xadmin.views import BaseAdminPlugin, ListAdminView
 
from django.template import loader
 
from  xadmin.plugins.utils import get_context_dict
 
class ListImportExcelPlugin(BaseAdminPlugin):
 
    import_excel = False
 
    def init_request(self, *args, **kwargs):
 
        return bool(self.import_excel)
 
    def block_top_toolbar(self, context, nodes):
 
        nodes.append(
 
            loader.render_to_string('xadmin/excel/model_list.top_toolbar.import.html', get_context_dict(context)))
 
xadmin.site.register_plugin(ListImportExcelPlugin, ListAdminView)



注意:Django2.0以后rander_to_string的第二个参数必须为dict格式,导入了get_context_dict方法,将context转换

2、将execl.py插件注册到xadmin的plugins中,修改site-packages/xadmin/plugins的__init__.py,

3、创建导入模板
xadmin/excel/model_list.top_toolbar.import.html

4.在Django项目的配置文件INSTALLED_APP中添加xadmin和crispy_froms
5.在应用中新建adminx.py文件,后台管理模型如需导入excel文件的,设置import_excel=True,则在该模型类的后台管理页面出现导入按钮
