Here is better code for it: filters = Idea.scopes.keys & Array.wrap(params[:filter]).map(&:to_sym) records = filters.inject(Idea.published) { |model, name| model.send(name) }.all First bonus feature is that it knows about all your named scopes, you don't have to specify them in the controller (business logic in your controller = wrong). Another bonus feature — multiple filters can be given: GET /resource?filter[]=foo&filter[]=bar Third bonus feature is that we didn't need to extend the language with a method that doesn't do absolutely anything. (Even `tap` does something and is incredibly useful.) -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
