mysql.W002

System check identified some issues:

WARNINGS:
?: (mysql.W002) MySQL Strict Mode is not set for database connection 'default'
    HINT: MySQL's Strict Mode fixes many data integrity problems in MySQL, such as data truncation upon insertion, by escalating warnings into errors. It is strongly recommended you activate it. See: https://docs.djangoproject.com/en/1.11/ref/databases/#mysql-sql-mode

解决: 在setting.py中添加选项

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'cmdb1',
        'HOST': '127.0.0.1',
        'USER': 'root',
        'PASSWORD': '123',
        'PORT': 3306,
        'CHARSET': 'utf8',
        'OPTIONS': {
            "init_command": "SET default_storage_engine='INNODB'"
        }
    }
}
DATABASES['default']['OPTIONS']['init_command'] = "SET sql_mode='STRICT_TRANS_TABLES'"
