RailsConf: Amy Hoy - Overcoming Scaffolding Addiction
Posted by Nick Sieger Fri, 23 Jun 2006 21:43:00 GMT
Scaffolding is not a swiss army knife, it’s more like a rusty spoon.
It’ll give you tetanus! Scaffolding leads to brain atrophy and
laziness. Leads to bad code, bad UI, etc. Instead, start from
script/generate is not inherently bad, it can write
necessary, tedious code for you.
script/generate controller kitten create view put_to_sleep
This gives you:
class KittenController < ApplicationController def create end def view end def put_to_sleep end end
Amy proceeds to break down a from-scratch, minimalist set of views, to underscore the point that it’s not too hard to not use scaffolding. I’d agree, it was so straightforward that unfortunately I’m going to omit the details here. Rolling your own without scaffolding is highly recommended.
Some of the items that you generally will experience in real world
apps but do not come in scaffolding are widgets for maintaining
relationships. Select lists based on a
belongs_to, checkbox groups
has_many are two examples.
Amy breaks these down as well and it turns out they’re pretty easy to
do. One snippet of code for updating checkboxes was succinct and
surprisingly readable, and made judicious use of the ruby array’s
behavior to add newly checked and remove newly unchecked items
Amy promised to post snippets and slides later on her blog, so go over to slash7 for more.
