Sorry if this has been asked before; it seems like a simple problem.
I have a controller called ItemController which displays information
about specific items to a user on various pages. The routing looks like
"items/:item/:action". Is there any way to automatically look up the
:item in the items table (it''s just an ID).
I tried:
before_filter { @current_item = Item.find(:first, @params[:item],
:include => [:set, :card]) }
but apperently filters don''t have access to params. Is there any other
simple way? Or is this somehow bad practice?

Or is this somehow bad practice?From the API docs: class WeblogController < ActionController::Base before_filter { |controller| false if controller.params["stop_action"] } end -- Cheers, - Jacob Atzen --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
