I'm new to Django and I've been assign to do a task about loggers. I have in mind a simple logger where INFO messages use a simple format and WARNING messages (and above) use a more complex one. This was my attempt:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'simple': {
'format': '{levelname} {message}',
'style': '{',
},
'verbose': {
'format': '{levelname}: {message} Time: [{asctime}] Module: [{module}] Process: [{process:d}] Thread: [{thread:d}] ',
'style': '{',
}
},
'handlers': {
'console_simple': {
'class': 'logging.StreamHandler',
'formatter': 'simple',
'level': 'INFO'
},
'console_verbose': {
'class': 'logging.StreamHandler',
'formatter': 'verbose',
'level': 'WARNING'
}
},
'loggers':{
'': {
'handlers': ['console_simple'],
'level': 'INFO'
}
}
}
As you can problably imagine, the problem is that WARNING messages or higher will be logged twice. I've though about using filters, but I couldn't find any undestandable explanation on the documentation.
I've found the filter below on this thread:
import logging
class InfoFilter(logging.Filter):
def filter(self, record):
return record.level == logging.INFO
The problem is that I don't know how to properly use it. I've never used filters before.
The Django logging documentation has the following example:
'filters': {
'special': {
'()': 'project.logging.SpecialFilter',
'foo': 'bar',
},
'require_debug_true': {
'()': 'django.utils.log.RequireDebugTrue',
},
},
Where they say that:
Defines two filters: project.logging.SpecialFilter, using the alias special. If this filter required additional arguments, they can be provided as additional keys in the filter configuration dictionary. In this case, the argument foo will be given a value of bar when instantiating SpecialFilter.
So, I believe that I need to give a value to logging.Filter the same way was "foo" received a value of "bar". The problem is that I have no idea on how to do that.
Am I at least on the right path? How can I use this filter? There are any other solutions?
