python之django入门

一.搭建开发环境

使用virualenv创建虚拟python环境

pip install virtualenv

[root@master djiango]# find / -name virtualenv
/usr/local/bin/virtualenv

[root@master h1]# source bin/activate
(h1) [root@master h1]#
(h1) [root@master h1]#

此时已经进入到虚拟环境；

(h1) [root@master h1]# deactivate      #退出虚拟环境
[root@master h1]#

[root@master .virtualenvs]# vim ~/.bashrc

 14 export WORKON_HOME=$HOME/.virtualenvs
 15 source /usr/local/bin/virtualenvwrapper.sh
[root@master .virtualenvs]# virtualenv -p /usr/local/bin/python3.5 h1
[root@master .virtualenvs]# virtualenv -p /usr/local/bin/python3.5 py35env

[root@master .virtualenvs]# workon h1
/usr/local/bin/python: No module named virtualenvwrapper
/usr/local/bin/python: No module named virtualenvwrapper

[root@master .virtualenvs]# pip install virtualenvwrapper

[root@master .virtualenvs]# workon h1
(h1) [root@master .virtualenvs]# workon py35env
(py35env) [root@master .virtualenvs]#

###############在虚拟环境下安装django##################

(py35env) [root@master .virtualenvs]# workon h1

在虚拟环境创建django项目：

(h1) [root@master ~]# mkdir projects
(h1) [root@master ~]# cd projects/
(h1) [root@master projects]# django-admin startproject test1
You have new mail in /var/spool/mail/root
(h1) [root@master projects]# ls
test1
(h1) [root@master projects]# cd test1/
(h1) [root@master test1]# ls
manage.py  test1

(h1) [root@master test1]# ls
  __init__.py settings.py urls.py wsgi.py

(h1) [root@master test1]# tree
.
├── manage.py
└── test1
├── __init__.py
├── settings.py
├── urls.py
└── wsgi.py

二.设计模型
