Catch a stacked variable by a controller

hi im new ruby on rails development currently im working with a
reservation system to start learning but im currently having a problem
with controllers and view

first i listed all the menu that the guest added inside the package that
he also added i listed them with this

_menuadded.html.erb

<h1>menu you added</h1>
<% @reservation_package.package_line_items.each do |menu|%>
<p><%= link_to menu.menu.name,

menu_reservation_reservation_package_reservation_package_pages_path(@reservation,@reservation_package,menu)
%>


<%= link_to “delete item”
,reservation_package_package_line_item_path(@reservation_package,menu),
:method => :delete%>


<%end%>

then i try to route to the next static page with this <p><%= link_to menu.menu.name, menu_reservation_reservation_package_reservation_package_pages_path(@reservation,@reservation_package,menu) %></p>

and the it produce this URL
http://localhost:3000/reservations/10/reservation_packages/39/reservation_package_pages/menu.29

im just wondering if how can i catch the menu that he opened i mean how
to catch this
localhost:3000/reservations/10/reservation_packages/39/reservation_package_pages/menu.29

in my menu semi static page controller where this route to,i tried this

@reservation_package =

ReservationPackage.find(params[:reservation_package_id])
@menu = Menu.find(params[:id])

but didn’t work at all im just wondering if im doing it right or if im
wrong can you give me a advice how to implement this kind of module?
thanks more power
