【英文标题】：Forcing sql_mode to "STRICT_TRANS_TABLES" still got warning Django

【问题描述】：

我正在使用Django 2.1.3，pymysql 0.9.2，mysql 5.7，python3.5

sql_mode in mysql:

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

db setting in django:

DATABASES = 

  'default': 
        'ENGINE': 'django.db.backends.mysql',
        ...,
        'OPTIONS': 
            'init_command': "SET sql_mode='STRICT_TRANS_TABLES'",
            'charset': 'utf8mb4'
         ,

我总是收到这样的警告：

/venv3.5/lib/python3.5/site-packages/pymysql/cursors.py:170: Warning: (3135, "'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode in a future release.")
  result = self._query(query)

/venv3.5/lib/python3.5/site-packages/pymysql/cursors.py:170: Warning: (3090, "Changing sql mode 'NO_AUTO_CREATE_USER' is deprecated. It will be removed in a future release.")
  result = self._query(query)

为什么我会收到上述警告？

非常欢迎任何评论。非常感谢。

【参考方案1】：

试试：

DATABASES = 
  'default': 
        'ENGINE': 'django.db.backends.mysql',
        ...,
        'OPTIONS': 
            'init_command': "SET sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER'",
            'charset': 'utf8mb4'
         ,
