Web Application in 4 days -- Lessons learned

After doing this project under such pressure, a number of lessons were learned.

(.) Do use a web framework. One that let's you get working quickly
(.) ERDs are absolutely necessary. When drawing your ERD, you should consider your ORM capabilities. It will prove to be more essential than having your ERD in 3NF.
(.) Your ORM will help you a lot of places, but fail in a couple. Know how to work with your low level SQL API.
(.) Performance is a non-issue. Code, Code, Code...
(.) Project management is harder than coding. Don't spend valuable development time of your team, reading books.
(.) Django should be DRYer.
(.) DRY your code. Don't underestimate it
(.) If you are writing lots of "if"s, refactor, refactor.
(.) Tests are so important. Don't skip them.
