    django 初始化数据库

    刷新数据库
    guoguos-MacBook-Pro:mysite guoguo$ python manage.py sqlflush
    BEGIN;
    SET FOREIGN_KEY_CHECKS = 0;
    TRUNCATE `auth_user`;

    COMMIT;

    清空数据库的数据
    guoguos-MacBook-Pro:mysite guoguo$ python manage.py flush
    You have requested a flush of the database.
    This will IRREVERSIBLY DESTROY all data currently in the 'django' database,
    and return each table to an empty state.
    Are you sure you want to do this?

        Type 'yes' to continue, or 'no' to cancel: yes

    删除数据库表结构
    mysql> drop tables auth_permission;
    Query OK, 0 rows affected (0.01 sec)

    初始化数据库

    guoguos-MacBook-Pro:mysite guoguo$ python manage.py migrate

    guoguos-MacBook-Pro:mysite guoguo$
    guoguos-MacBook-Pro:mysite guoguo$

    在setting.py INSTALLED_APPS = 中增加 guoguo 项目

    INSTALLED_APPS = [

        'django.contrib.admin',
        'django.contrib.auth',
        'django.contrib.contenttypes',
        'django.contrib.sessions',
        'django.contrib.messages',
        'django.contrib.staticfiles',
    ]


    在项目里生成一个表文件
    guoguos-MacBook-Pro:mysite guoguo$ python manage.py makemigrations guoguo
    Migrations for 'guoguo':
      guoguo/migrations/0001_initial.py
        - Create model Person

    生成表结构
    guoguos-MacBook-Pro:mysite guoguo$ python manage.py sqlmigrate guoguo 0001
    BEGIN;
    --
    -- Create model Person
    --
    CREATE TABLE `guoguo_person` (`id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `first_name` varchar(30) NOT NULL, `last_name` varchar(30) NOT NULL);
    COMMIT;


    把表结构导入数据库


    guoguos-MacBook-Pro:mysite guoguo$ python manage.py migrate
