Create a simple asset management platform using Django1.11
1: first create a django project
[root@localhost opt] # django-admin startproject ops
CommandError:'/ opt/ops' already exists
[root@localhost opt] # cd ops
[root@localhost ops] # tree
.
├── manage.py
└── ops
├── _ _ init__.py
├── settings.py
├── urls.py
└── wsgi.py
1 directory, 5 files
[root@localhost ops] #
2: continue to create an APP
[root@localhost ops] # django-admin startapp polls
[root@localhost ops] # tree
.
