Hi, yes, it's absolutely possible. Refer to Django docs about logging
(https://docs.djangoproject.com/en/1.10/topics/logging/
<https://docs.djangoproject.com/en/1.10/topics/logging/>) and logging docs
(https://docs.python.org/3/library/logging.config.html#logging-config-dictschema
<https://docs.python.org/3/library/logging.config.html#logging-config-dictschema>).
What you're looking for is logging formatters and filters. Here's an example:
LOGGING = {
'formatters': {
'detailed': {
'format': '%(asctime)s %(module)s %(levelname)-8s- %(some_id)s
%(message)s',
...
},
},
'handlers': {
'default': {
'formatter': 'detailed',
'filters': ['some_id_filter'],
...
},
...
},
'filters': {
'some_id_filter': {
'()': 'package.module.SomeIdFilter',
},
},
...
}
