5.2离线使用xadmin包

把xadmin包放到项目目录下，便于修改xadmin中的代码。

首先解压下载好的 xadmin-django2.zip 压缩包，拷贝子文件夹中的xadmin文件夹，到项目中新建extra_apps文件夹，放入xadmin。

虚拟环境中卸载 xadmin安装包：

pip uninstall xadmin

把extra_apps目录mark为sources root

到settings中设置extra_apps文件夹的跟路径：

sys.path.insert(0, os.path.join(BASE_DIR, 'extra_apps'))

这样访问xadmin时自动从配置文件中查找相应的路径。

如果对添加的用户进行修改时，会弹出错误：

　　pycharm中的错误信息是：

　　具体解决办法是：https://blog.csdn.net/yuhan963/article/details/79167743

就是在xadmin中的 widgets.py文件的第 75行，

input_html = [ht for ht in super(AdminSplitDateTime, self).render(name, value, attrs).split('\n') if ht != '']

换成：

input_html = [ht for ht in super(AdminSplitDateTime, self).render(name, value, attrs).split('/><') if ht != '']
input_html[0] = input_html[0] + "/>"
input_html[1] = "<" + input_html[1]

ctrl + alt +f 格式化代码后，行号变了

再看浏览器，ok：
