5 超级用户和管理

migrate数据库

执行migrate命令生成数据库表

python manager.py migrate

(env) E:\Computer\virtualenv\iblog\csblog>python manage.py migrate
Operations to perform:

创建超级用户

python manager.py createsuperuser

(env) E:\Computer\virtualenv\iblog\csblog>python manage.py createsuperuser
Username (leave blank to use 'administrator'): bhe001
Email address:
Password:
Password (again):
This password is too short. It must contain at least 8 characters.
This password is entirely numeric.
Password:
Password (again):
Superuser created successfully.

邮箱地址可选。密码在该版本有一些限制，至少为8个字符。

# Database
# [https://docs.djangoproject.com/en/1.11/ref/settings/](https://docs.djangoproject.com/en/1.11/ref/settings/)#databases

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

配置

查看settings.py，默认的数据库位sqlite，这可以满足我们一般的练习需求，如果产品化的时候，我们可以迁移到MySQL，Oracle等数据库上。

在创建完超级用户之后，我们接下来可以访问http://127.0.0.1:8000/admin，进行后台管理，默认有权限相关的配置，这些在默认的INSTALLED_APPS里面已定义。

# Application definition

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

我们也可以直接在后台添加新的用户。

其他的一些配置的介绍

ROOT_URLCONF，这是根URL的配置，指示URL定义位置

ROOT_URLCONF = 'csblog.urls'
