Hi, I think that this is made from a plugin or something in /lib/, but i really don't know which is the better way: I have this in my MediasController: def mediatype_medias_options if params[:id] begin @mediatype = MediaType.find(params[:id]) render :inline => "<%= options_from_collection_for_select @ mediatype.medias, 'id', 'name' %>" rescue Exception render :nothing => true end else render :nothing => true end end I use it from a form, that sends a mediatype id, and this renders <options> for a select (it's something like a hier. select). Since i must use this kind of thing into some controllers, i wish to follow the DRY principle, but don't know how. Could you please give me some advice? Thanks.

Put the code in: app/controllers/application.rb and it will be available to all controllers. -- -- Tom M.

I'd just create a helper module in the controllers directory and then require/include it in the controllers you need the method in.
