Sorry I wasn't clear enough. Here's the stack trace:

Also, I have a wrapper to call db_logger, which you can see from the
stacktrace:
def log_to_db(self, level, msg, log_type, extra={}):
db_logger = logging.getLogger('db_logger')
extras = {
'category': log_type.category.name,
'sub_category': log_type.sub_category.name,
'type_id': log_type.type_id,
}
extras.update(extra)
db_logger.log(level, msg, extra=extras)
My DB Handler looks like this:
class DatabaseHandler(logging.Handler):
def emit(self, record):
user = getattr(record, 'user', None)
category = getattr(record, 'category', None)
sub_category = getattr(record, 'sub_category', None)
type_id = getattr(record, 'type_id', None)
timestamp = datetime.strptime(record.asctime,
settings.LOG_DATE_FORMAT)
from history.models import LogRecord
LogRecord.objects.create(timestamp=timestamp,
level=record.levelname,
category=category, sub_category=sub_category,
type_id=type_id,
message=record.message, user=user)
Thanks again.
