Where people struggle learning Django

Over the last 3 years or so I've helped a bunch of companies, small and large, switch to Django. As part of that, I've done a lot of teaching Django (and Python) to people new to the platform (and language). I'd estimate I've trained something around 200-250 people so far. These aren't people new to programming — indeed, almost all of them are were currently employed as software developers — but they were new to Python, or to Django, or to web development, or all three.

In doing so, I've observed some patterns about what works and what doesn't. Many (most) of the failings have been my own pedagogical failings, but as I've honed my coursework and my skill I'm seeing, time and again, certain ways that Django makes itself difficult to certain groups of users.

This document is my attempt at organizing some notes around what ways different groups struggle. It's not particularly actionable — I'm not making any arguments about what Django should or shouldn't do (at least

Basic metabolism mechanics

Water

Water - your metabolism needs it. Have a full hand-held bottle nearby at all times. Drink liberally - most estimates of recommended amount fall between 3-5 liters per day (a lot more than what you will usually drink).

Infact, forget all other drinks, especially soft drinks and artificial juices. Most of them are sugary and will become fat minutes after you drink them. Replace them all with water.
