All things are difficult before they are easy.
OK, so I just realized there was an acts_as_textilized plugin, but ignore that for right now. I wrote a textilize helper that I'm using in a lot of my models. Without adding to what the functionality, how would you do it?
One thing that stumped me was generating the list of methods for the before_save filter. I wanted this:
before_save :about_to_html, :body_to_html
from an array that has [:about_to_html, :body_to_html] instead of calling before_save for each method separately.
