Hi George,
I'm not aware that what you want would be possible in the Merb. The
"and it figures out the url "context" by itself?" is kind a magic,
isn't it? It suppose that you'll use the same variable naming all the
time for your instance variables.
What I suggest is to write helpers. You can have set of controllers
which can use the same helpers. There you can have helper like
setup_client_and_trip() or even something more generic which sets your
@client and @trip variables.
Put in application.rb or any controller you want
"before :setup_client_and_trip". And than write helper
client_trip_elements_url like this:
def client_trip_elements_url(param = {})
resource(@client,@trip,:elements, param)
end
That way you have your setup code and URL generation in one place. And
it will simplify your code.
