Django - logging unique ID

Question

I am assigning a unique ID to every incoming request and want to this to be automatically included in the logs whenever logging is done (without explicitly including it in all places). I am using a middleware to generate and store this unique ID in a thread local.

I want to modify Django's logging formatter to include this unique ID directly:

LOGGING = {
    ...
    'formatters': {
        'full': {
            'format': '%(asctime)s %(levelname)s %(name)s - %(message)s',
        }
    }
    ...
} 

How do I add the unique id component to the formatter without explicitly adding at each log statement?

Use a Filter: the technique is described in this post. Though it refers to IP addresses, you can just as easily use the approach to log your unique request IDs.
