The problem is that the responsibilities are not already sorted going in.
Each area belongs_to a responsibility. I have the list of all of the areas,
I want to group them by responsibility, and I want to sort the result by
some field within the responsibility. Currently, I have something like:
@areas = Area.find(:all)
Is there some way to order that ahead of time by
areas.responsibility.some_field?
Hmmm.... perhaps I'm thinking of this backwards. (It wouldn't be the first
time.) Do I really want to do something like:
@responsibilities = Responsibility.find(:all)
Hmmmm.... that looks like the right avenue to have taken in the first
place....
now... if I could just figure out how to comment out blocks of ERB code,
this would be much easier to test and then back out of if it goes awry.
