Django: how to set log level to INFO or DEBUG
提问by kev
I tried to change the debug level to DEBUG in Django because I want to add some debug messages to my code. It seems to have no effect.
我试图在 Django 中将调试级别更改为 DEBUG，因为我想向我的代码添加一些调试消息。好像没什么效果。
My logging configuration:
我的日志配置：
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'simple': {
'format': '%(levelname)s %(message)s'
},
},
'handlers': {
'console':{
'level':'DEBUG',
'class':'logging.StreamHandler',
'formatter': 'simple'
},
},
'loggers': {
'django.request':{
'handlers': ['console'],
'propagate': False,
'level': 'DEBUG',
},
},
}
Code:
代码：
import logging ; logger = logging.getLogger(__name__)
logger.debug("THIS MESSAGE IS NOT SHOWN IN THE LOGS")
logger.warn("THIS ONE IS")
Output on the console:
控制台输出：
WARNING:core.handlers:THIS ONE IS
I also have tried setting DEBUG = False and DEBUG = True in my settings file. Any ideas?
我也试过在我的设置文件中设置 DEBUG = False 和 DEBUG = True 。有任何想法吗？
Edit:If I set the log level on the logger directly, it works:
编辑：如果我直接在记录器上设置日志级别，它会起作用：
import logging ; logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
logger.debug("THIS MESSAGE IS NOT SHOWN IN THE LOGS")
Output:
输出：
DEBUG:core.handlers:THIS MESSAGE IS NOT SHOWN IN THE LOGS
WARNING:core.handlers:THIS ONE IS
But: It seems the config file is totally ignored. It prints both statements alwayseven if I set both entries in the config back to ERROR. Is this the correct behaviour or am I still missing something?
但是：似乎配置文件被完全忽略了。即使我将配置中的两个条目都设置回 ERROR，它也会始终打印这两个语句。这是正确的行为还是我仍然遗漏了什么？

You need to add e.g.
你需要添加例如
'core.handlers': {
'level': 'DEBUG',
'handlers': ['console']
}
in parallel with the django.requestentry, or
与django.request条目并行，或
'root': {
'level': 'DEBUG',
'handlers': ['console']
}
in parallel with the 'loggers' entry. This will ensure that the level is set on the logger you are actually using, rather than just the django.requestlogger.
与“记录器”条目并行。这将确保在您实际使用的记录器上设置级别，而不仅仅是django.request记录器。
Update:To show messages for all your modules, just add entries alongside django.requestto include your top level modules, e.g. api, handlers, coreor whatever. Since you haven't said exactly what your package/module hierarchy is, I can't be more specific.
更新：要显示所有模块的消息，只是添加条目旁边django.request，包括您的顶层模块，例如api，handlers，core或什么的。由于您还没有确切说明您的包/模块层次结构是什么，我不能更具体。

I fixed it by changing
我通过改变来修复它
LOGGING = {
...
}
to:
到：
logging.config.dictConfig({
...
})
For example to log all messages to the console:
例如，将所有消息记录到控制台：
import logging.config
LOGGING_CONFIG = None
logging.config.dictConfig({
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'console': {
# exact format is not important, this is the minimum information
'format': '%(asctime)s %(name)-12s %(levelname)-8s %(message)s',
},
},
'handlers': {
'console': {
'class': 'logging.StreamHandler',
'formatter': 'console',
},
},
'loggers': {
# root logger
'': {
'level': 'DEBUG',
'handlers': ['console'],
},
},
})
