Rails - Dec 2005 - Shared code for controllers

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.

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