parameterized associations in my ActiveRecord classes. Basically I
need something that is a cross between named scopes and standard
associations (has_many specifically).
I''m wondering if such a thing exists or, if not, if anyone else has an
elegant, equivalent solution?
Example:

Teams. (Think of this in an athletic context where users are athletes,
programs are universities). So my
