###一、命令行工具###

django-admin.py是Django的一个用于管理任务的命令行工具，manage.py是对django-admin.py的简单包装，每个Django Project里面都会包含一个manage.py

语法：

root># django-admin.py <subcommand> [options]

root># manage.py <subcommand> [options]

subcommand是字命令； options是可选的

###二、常用子命令###

1、新建一个django项目
django-admin.py startproject project-name


2、新建一个app
python manage.py startapp app-name


3、运行开发服务器
python manage.py runserver 0.0.0.0:8000
或
python manage.py runserver 0:8000


4、同步数据库
python manage.py makemigrations   --生成数据库同步脚本
python manage.py migrate  --同步数据库

注意：Django 老版本可以使用用syncdb
python manage.py syncdb


5、清空数据库
python manage.py flush

此命令会询问是 yes 还是 no, 选择 yes 会把数据全部清空掉，只留下空表。


6、创建超级管理员
python manage.py createsuperuser


7、导出数据、导入数据
python manage.py dumpdata appname > appname.json
python manage.py loaddata appname.json


8、django项目环境终端
python manage.py shell

如果你安装了bpython或者ipython，会自动调用他们的界面


9、数据库执行命令
python manage.py dbshell

django会进行到settings中设置的数据库，如果是mysql或者postgresql，会要求输入用户名和密码
在这个终端可以输入sql语句

10、编译语言文件
python manage.py compilemessages

11、创建语言文件
python manage.py makemessages

###三、manage.py特有的一些子命令

1、创建超级管理员
python manage.py createsuperuser


2、修改密码
python manage.py changepassword

3、清除sessions
python manage.py clearsessions
