Re: Django 1.3 logging not working as I'd expect

[Scott Danzig]

Okay.. update.. it does seem to work right, even without forcing the
initialization as you suggested.. which is a relief.. Was losing my mind
(maybe Django 1.3 doesn't require the settings.LOGGING?)  While testing with
prints, I realized the view function I thought should be called wasn't
called until AFTER login..  Oops :)

Thanks all.

Thanks Gelonida.. tried your suggestion and added those two lines before my
import logging ... unfortunately no change.  Perhaps it's not
straightforward.  Sounds like it wasn't obvious to you either.

@Reinout: Thanks, but yeah, already tried logging from a view function..
didn't work...

@Bruno: Yeah, I am using the dev server.  I have been using from django.conf
import settings within my app to access settings..although unless I do
something like what Gelondia suggested... with the LOGGING =
settings.LOGGING, I'm not sure how the logging normally "invokes" the
settings.  The way I see it, django magically loads the settings at some
point in the background, then when you use the logging, it accesses those
settings, and there's a certain time when these settings become accessible
so this works.  But it's not working like this, so perhaps I'm mistaken.  So
you're saying to replace all instances of "from django.conf import settings"
with just "import settings"?  Or the other way around?  Not sure about what
importing only twice does, and how importing settings more or less affects
this.

Thanks all for answering.

Re: login auth issue - beginner

[Scott Danzig]

It reports you're missing the key "username" from your POST... so the first 
thing I'd check for is ... do you have a line like this in your login 
template page?:

Django 1.3 logging not working as I'd expect

[Scott Danzig]

I have Django 1.3 working with Python 2.7 and MySQL 5.5 on Mac OSX Lion...

I'm betting I'm missing something straight forward, but:

I have a simple Django app in development that uses a dictConfig setting 
simpler than the default in settings.py:

LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s %(process)d 
%(thread)d %(message)s'
},
},
'handlers': {
'console':{
'level':'DEBUG',
'class':'logging.StreamHandler',
'formatter': 'verbose'
},
'file':{
'level':'DEBUG',
'class':'logging.FileHandler',
'formatter': 'verbose',
'filename': 'testdjango.log',
},
},
'loggers': {
'testlogger': {
'handlers': ['console','file'],
'level': 'DEBUG',
'propagate': True,
   },
},
}


Then later in code that I know is run... (I tried in my app's views.py and 
also the backend).. I put something like this:

import logging
logger = logging.getLogger('testlogger')
logger.warn('hello')
logger.info('please appear')


And I just don't see it, neither in the console, nor the file.

I have also tried something like this:
import logging
logger = logging.getLogger('otherlogger')
hdlr = logging.FileHandler('newlogger.log')
formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)s')
hdlr.setFormatter(formatter)
logger.addHandler(hdlr) 
logger.setLevel(logging.DEBUG)
logger.warn('In settings.py!')

And that doesn't work either, unless I put it right in settings.py.. in 
which case it appears 4 times, because, from what I understand, settings.py 
gets loaded that many times.  But then this doesn't work in the 
views.py/backend .. perhaps because the dictConfig gets loaded after 
settings.py is run?  I don't know.

I'm hoping for someone to give me a heads up about what I'm missing here. 
 Django's been pretty easy to deal with until I started to look into 
logging.

Thanks.
