Django: logging only for my project's apps

Question

By default I can enable logging in settings.py in the LOGGING configuration by creating a logger "" which will catch all logs. But what if I only want to see logging from my project's apps as opposed to Django internals?

I can imagine explicitly getting a logger in each of my Django app modules and naming it by some convention, e.g. logging.getLogger("myproject." + __file__). Then I can create a logger called 'myproject' (in SETTINGS) which picks up all of these to output. I'd prefer not to hardcode my project name, so I'd do some os.path logic on ___file___ to extract the full namespace up to the file at any arbitrary depth.

At this point, I stop and wonder is there an easier way?

You could use a scheme like the following to create identical loggers for all of your local apps without having to manually add them all to the logging configuration.

First, split out your local apps:

LOCAL_APPS = [
    'myapp1',
    'myapp2',
    ...
]

THIRD_PARTY_APPS = [
    'django. ...',
    ...
]

INSTALLED_APPS = LOCAL_APPS + THIRD_PARTY_APPS

Next create the logger configuration for your local apps:

local_logger_conf = {
    'handlers': ['my_handler',],
    'level': 'DEBUG',
}

Finally, define your loggers as follows:

'loggers': { app: copy.deepcopy(local_logger_conf) for app in LOCAL_APPS }
