ruby on rails - Routing the URL using values from database? -

i have controller streams_controller , model streams.

class streamscontroller < applicationcontroller   def new     @stream = stream.new   end    def create     @stream = stream.new(params[:stream])     if @stream.save         flash[:success] = "welcome!"         redirect_to @stream     else         render 'new'     end   end     def show     @stream = stream.find(params[:id])   end end 

and

class stream < activerecord::base     attr_accessible :name, :email, :password, :password_confirmation     before_save { |stream| stream.name = name.downcase }      has_secure_password . . . 

basically work show method, have go localhost/streams/[id] [id] id of particular stream. possible reroute url go this: localhost/[name] [name] :name attribute of stream model?

so new url created every time new stream created, , correspond name of stream in database.

how go implementing this?

anyways, or thoughts appreciated!

i make streams part of url short possible, not empty (to avoid collisions in case of using names instead of ids).

resources :streams, path: 's' 

url /s/stream-a isn't big compromise.

about using name instead of id in url see this railscast.
