The design URL is distributed by the way Xadmin_demo

Such as

Urlpatterns = [
    URL (r ' ^xadmin/', ([
URL (r ' ^add/$ ', Views.add)
URL (r ' ^delete/$ ', views.delete)
], None,none)),
This completes the first level distribution

Then make a self-designed URL
Need 3 sheets, additions and deletions, 12 URLs
Such as
127.0.0.1:8000/xadmin/app01/add/

127.0.0.1:8000/xadmin/app01/delete/
