在xadmin后台添加课程页面要关联org，默认是下拉框，视频13-3里面有个地方讲可以把下拉框修改为通过ajax方式展示，

我具体方式如下：

class CourseOrgAdmin(object):

list_display = ['name', 'desc','click_nums','fav_nums','image','address','city','add_time']

search_fields = ['name', 'desc','click_nums','fav_nums','image','address','city']

list_filter = ['name', 'desc','click_nums','fav_nums','image','address','city','add_time']

relfield_style = 'fk-ajax'   #以ajax方式加载外键

但是在输入框搜索的报错如下：

Starting development server at http://0.0.0.0:9999/

Quit the server with CONTROL-C.

Internal Server Error: /xadmin/organization/courseorg/
