Don’t F**king Repeat Yourself
Carl has suggested some interesting improvements to the standard Rails migrations:
So, you’re a Rails developer? CHECK! You have this great idea for a new application, the one which will surely get Yahoo and Google involved in a bidding war? CHECK! But you don’t actually start developing it because you are fed up having to run script/generate model model_name, editing the migration for the table, writing the tests for all the rules which are implied by the database (Such as maximum lengths for columns and column uniqueness), and then editing the model to pass those tests? CHECK!
(digg here if you’re that way inclined)
