I have class A.
I have a class B with attributes c and d.
A has many Bs.
I get an instance of A using
a = find_by....
I can get a listing (enumeration) of values for attribute b using map
function.
a.b.map{ |x| x.c}
c1
c2
c3
However, I want c and d returned and paired together in an array like a
2-d array.
c1 d1
c2 d2
c3 c3
What's the best way to do this? Map won't work, correct?
