是什么创建这些Django数据库日志条目

Question

我的开发服务器的django数据库日志文件很大，因为每分钟每分钟记录一次特定事件：

[10/Sep/2017 21:02:02] DEBUG [django.db.backends:89] (0.001) DELETE FROM "django_session" WHERE "django_session"."expire_date" < '2017-09-10T21:02:02.514421+00:00'::timestamptz; args=(datetime.datetime(2017, 9, 10, 21, 2, 2, 514421, tzinfo=<UTC>),)
[10/Sep/2017 21:03:02] DEBUG [django.db.backends:89] (0.002) DELETE FROM "django_session" WHERE "django_session"."expire_date" < '2017-09-10T21:03:02.265801+00:00'::timestamptz; args=(datetime.datetime(2017, 9, 10, 21, 3, 2, 265801, tzinfo=<UTC>),)
[10/Sep/2017 21:04:02] DEBUG [django.db.backends:89] (0.002) DELETE FROM "django_session" WHERE "django_session"."expire_date" < '2017-09-10T21:04:02.033147+00:00'::timestamptz; args=(datetime.datetime(2017, 9, 10, 21, 4, 2, 33147, tzinfo=<UTC>),)

我的设置文件包含这些与会话相关的指令：

DEBUG = True
SESSION_COOKIE_SECURE = True
MIDDLEWARE_CLASSES = (
    # ...
    'django.contrib.sessions.middleware.SessionMiddleware',
    # ...
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    # ...
)
SESSION_ENGINE = 'django.contrib.sessions.backends.cached_db'
SESSION_COOKIE_AGE = 60 * 60
# Refresh session state with every request.  This effectively creates
# a "sliding" session expiration.  A user will remain signed in so
# long as they send at least one request every SESSION_COOKIE_AGE minutes.
SESSION_SAVE_EVERY_REQUEST = True
INSTALLED_APPS = [
    # ...
    'django.contrib.sessions',
    # ...
]

我在日志设置中没有任何与会话相关的内容。是什么导致这些调试条目，有什么方法可以禁用它们或至少降低其频率？

黄金答案在此处添加 settings.py file.tif.you您需要删除或评论这些行，这些生成数据库日志entriy

 DEBUG = True
 '''

     'require_debug_true': {
         '()': 'django.utils.log.RequireDebugTrue',
     }
 },
 'handlers': {
