Hmmm... that wasn't as helpful as I had hoped. Oh well.
Going back to your earlier post, I can see a couple of problems.
Firstly, your __getitem__ method always returns None. You need to return
the result.
Secondly, this works for me:
import logging
class ExtraInfo(object):
def __getitem__(self, name):
if name == 'host':
result = 'foo'
return result
def __iter__(self):
keys = ['host',]
keys.extend(self.__dict__.keys())
return iter(keys) # better than keys.__iter__
def setup(filename='/tmp/foo.log'):
log = logging.LoggerAdapter(logging.getLogger('foo'), ExtraInfo())
logging.basicConfig(
level=logging.DEBUG,
format=Date-Time: %(asctime)s
Host: %(host)s
%(levelname)s:
%(message)s,
datefmt=%Y-%m-%dT%H:%M:%S%z,
filename=filename,
filemode='w')
return log
log = setup()
log.error('testing ...')
log.debug('something happened')
log.critical(it's the end of the world as we know it!)
Hope this helps.

Thanks Steven! You give me the idea.
* In the setup(), is not necessary to use:
log = logging.LoggerAdapter(logging.getLogger('foo'), ExtraInfo()
neither return a value:
return log
* The problem is that I'm using the logger at module-level so I had in
each module:
logger = logging.getLogger(__name__)
but there is to use:
logger = logging.LoggerAdapter(
logging.getLogger(__name__), log.ExtraInfo())

Extra fields for logging
I'm trying to add some extra fields to logging, I'm following this
information [1] but it faills in my case.
# module logger.py
import logging
class ExtraInfo(object):
def __getitem__(self, name):
if name == 'host':
result = 'foo'
def __iter__(self):
keys = ['host',]
keys.extend(self.__dict__.keys())
return keys.__iter__()
def setup(filename='/tmp/foo.log'):
log = logging.LoggerAdapter(logging.getLogger('foo'), ExtraInfo())
#log = logging.LoggerAdapter(logging.getLogger('foo'), {'host':
'bar'})
logging.basicConfig(
level=logging.DEBUG,
format=(
Date-Time: %(asctime)s\n
Host: %(host)s\n
%(levelname)s:\n
%(message)s),
# %f = microseconds is not showed, bug?
datefmt=%Y-%m-%dT%H:%M:%S%z,
filename=filename,
filemode='w')
# module another.py
import logger
logger.setup()
logging.getLogger('foo')
logging.error('testing ...')
I get = KeyError: 'host'
