###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：
1root># django-admin.py <subcommand> [options] 2 3root># manage.py <subcommand> [options] 4 5subcommand是字命令； options是可选的
###二、常用子命令###
11、新建一个django项目 2django-admin.py startproject project-name 3 4 52、新建一个app 6python manage.py startapp app-name 7 8 93、运行开发服务器 10python manage.py runserver 0.0.0.0:8000 11或 12python manage.py runserver 0:8000 13 14 154、同步数据库 16python manage.py makemigrations --生成数据库同步脚本 17python manage.py migrate --同步数据库 18 19注意：Django 老版本可以使用用syncdb 20python manage.py syncdb 21 22 235、清空数据库 24python manage.py flush 25 26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。 27 28 296、创建超级管理员 30python manage.py createsuperuser 31 32 337、导出数据、导入数据 34python manage.py dumpdata appname > appname.json 35python manage.py loaddata appname.json 36 37 388、django项目环境终端 39python manage.py shell 40 41如果你安装了bpython或者ipython，会自动调用他们的界面 42 43 449、数据库执行命令 45python manage.py dbshell 46 47django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 48在这个终端可以输入sql语句 49 5010、编译语言文件 51python manage.py compilemessages 52 5311、创建语言文件 54python manage.py makemessages 55 56
