Relevant documentation is here: http://guides.rubyonrails.org/association_basics.html (For similar results, google for "Rails Guides <term on interest>"). If I understand correctly, your case would be a perfect case for has_many :through (and _not_ habtm) because you need Classification attributes on each association between a Company and a Category (then the Classification table is the association table between Company and Category). Try to work out the code for your case from that documentation. If you have difficulties with it, please come back with your specific problems, showing us the code your wrote.
