Logging in Django - django

Question

I'm trying to figure out logging in Django (checking out Python logging itself for the first time too for that matter).
I have the following in my settings.py
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'handlers': {
'file': {
'level': 'DEBUG',
'class': 'logging.FileHandler',
'filename': '/home/afzalsh/logs/debug.log',
},
},
'loggers': {
'django.request': {
'handlers': ['file'],
'level': 'DEBUG',
'propagate': True,
},
},
}
This is the exact code as what Django documentation has as the first example.
Then I have a log message in a class based view.
import logging
.
.
.
class StationHome(View):
.
.
.
def post(self,request, pk):
station = Station.objects.get(pk=pk)
form = StationForm(request.POST, instance=station)
if form.is_valid():
logger = logging.getLogger(__name__)
logger.error("Yep!")
form.save()
return HttpResponseRedirect(reverse("home_station",
kwargs={'pk':pk},
)
)
else:
return HttpResponse("Form Invalid")
.
.
.
The debug.log file has got created but it doesn't get populated with any message on going through the particular code. The expected process do happen.

Answer 1

You've requested the logger associated with __name__, so you get one named the same as the current Python module. However, the only one you've actually configured is "django.request". You should use that in your call to getLogger instead.

Answer 2

In your settings your handler dict contains level 'debug' for file where as in your code you are using 'error' level to log.
logger.error("Yep!")
Try using 'debug' level in your code. Something like this:
logger.debug("Yep!")
also posting my settings here so that you can use that as a reference.
