Now what does all of this mean?
Formaters I like it to come out as the same style as ./manage.py runserver
Handlers - I want two logs - a debug text file, and an info console. This allows me to really dig in (if needed) and look at a text file to see what happens under the hood.
Loggers - Here is where we nail down what we want to log. In general django gets WARN and above - the exception (hence propagate) is the backends where I love to see the SQL calls since they can get crazy.. Last is my app were I have two handlers and push everything to it.
Now how do I enable MYAPP to use it...
Per the documentation put this at the top of your files (views.py)..

import logging
log = logging.getLogger(__name__)
// Then to get something out do this.
log.debug("Hey there it works!!")
log.info("Hey there it works!!")
log.warn("Hey there it works!!")
log.error("Hey there it works!!")
// Log levels are explained here and for pure python here.
