Routes

Hello,
I am new to ruby.Can someone tell me
what do i need to write in the routes.rb so that i can use the following
to edit a record.

form_for
:organisation,:url=>organisation_path(@organisation),:html=>{:method=>'put'}
do>org>

Thank you.

map.resources :organisations

Whoops, a bit trigger happy there!
