wondering if there is a way to do this..
say we have a model that has attributes length and width..
:length and :width
and we have a class square:
class Square < ActiveRecord::Base
def area
area = length * width
end
end
is there a way i can do a:
Square.find(:area => '144')
to produce any squares with an area of 144?
i know there are lots of other ways to do this, but in the case i am
working on, a find would be REALLY clean..
