As described here http://guides.rubyonrails.org/active_record_querying.html#eager-loading-associations
I think what you want is something like products = Product.includes(:category) This will eager load the category association when you load the Product objects. You must specify the inverse relationship (in product.rb you must have belongs_to :category) for this to work.
