@areas = Area.all(:include => :videos)
In my rails application an Area has_many Videos.
I wrote a (part of a) view that lists all the areas, and for each area shows the count
of the videos that belong to it.
My code works, but makes a different database query for each Area, which I suppose
is not terribly efficient -- do you know of any way to improve it? Thanks!
