My first question would be why are you using find_by_sql? Why not use
the normal rails ActiveRecord methods. See
http://guides.rubyonrails.org/active_record_querying.html
and
http://guides.rubyonrails.org/association_basics.html
I assume you have already worked through the getting started guide and
some tutorials such as railstutorial.org which is free to use online.
