/clients/1/trips/1/elements <- this should be a named_resource
then you can use the url() helper
Example:
I have in my router.rb
match("/referrers/:id/covernotes/:covernote_id/edit(.:format)", :method =>
[:get] ).to(:controller => "referrers_covernotes", :action => "edit"
).name("referrer_edit_covernote")
Then I can use the url helper to sub in the params
%a.one{:href => url(:referrer_edit_covernote, @active_referrer.id,
@covernote["_id"])} Edit
I got stuck using nested resources so went verbatim and specified all my
routes by hand.
This took a little bit more effort however the exercise allowed me to "get"
how the router works and how I can use it when I need to away from the
"merb-gen resource"
