(Minimal) usage of django logger

--To be exact, python logger --In django, write the settings in settings.py and use it. ――There are many other things you can do, but first of all, only the minimum

Write the following settings in settings.py

LOGGING = {
    'version': 1,   #If you do not set this, you will get angry
    'formatters': { #Specify the output format in string format
        'all': {    #For output format`all`Give it the name
            'format': '\t'.join([
                "[%(levelname)s]",
                "asctime:%(asctime)s",
                "module:%(module)s",
                "message:%(message)s",
                "process:%(process)d",
                "thread:%(thread)d",
            ])
        },
    },
    'handlers': {  #Setting where to put the log
        'file': {  #Give a name to the setting of where to put it`file`Is named
            'level': 'DEBUG',  #Meaning to handle logs of DEBUG or higher
            'class': 'logging.FileHandler',  #Specify the class to output the log
            'filename': os.path.join(BASE_DIR, 'django.log'),  #Where to put it out
            'formatter': 'all',  #Specify which output format to output by name
        },
        'console': { #Another setting for where to put it, this setting`console`Name
            'level': 'DEBUG',
            #This specifies the class that outputs to standard output
            'class': 'logging.StreamHandler', 
            'formatter': 'all'
        },
    },
    'loggers': {  #Set what kind of logger you have
        'command': {  #Define a logger named command
            'handlers': ['file', 'console'],  #File mentioned above,Output with console settings
            'level': 'DEBUG',
        },
    },
}

Create and call such a function

def info(msg):
    logger = logging.getLogger('command')
    logger.info(msg)

info("hello!")

Output to django.log and standard output in the following format

[INFO]	asctime:2015-09-23 16:27:11,291	module:my_module_name	message:hello!	process:97649	thread:140735161512704
