Newbie :: multiple database

@resource =Resource.find(params[:id], :include =>[:projects, :trainings]

As long as your associations are set in the models, this will work.

class Resource < ActiveRecord::base
has_many :trainings

has_many :projects

end

That will work.

Rails has an api at http://api.rubyonrails.com where this is all documented. You should make sure to give that a look if you have additional questions.
