python3 manage.py migrate：?: (mysql.W002) MySQL Strict Mode is not set for database connection 'default'

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.djangoprojec
t.com/en/dev/ref/databases/#mysql-sql-mode

解决办法：settings.py文件夹加入DATABASES['OPTIONS']['init_command'] = "SET sql_mode='STRICT_TRANS_TABLES'"

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'django_test',
        'USER':'root',
        'PASSWORD':'',
        'HOST':'localhost',
        'PORT':'3306',
        #下面是新加入的
        'OPTIONS':{
            'init_command':"SET sql_mode='STRICT_TRANS_TABLES'",
            'charset':'utf8mb4',
        },
    }
}
