Did you define it in your routes.rb?
What is the output of rake routes?

is not, how i do that ?

todos GET /todos(.:format)
{:action=>“index”, :controller=>“todos”}
POST /todos(.:format)
{:action=>“create”, :controller=>“todos”}
new_todo GET /todos/new(.:format)
{:action=>“new”, :controller=>“todos”}
edit_todo GET /todos/:id/edit(.:format)
{:action=>“edit”, :controller=>“todos”}
todo GET /todos/:id(.:format)
{:action=>“show”, :controller=>“todos”}
PUT /todos/:id(.:format)
{:action=>“update”, :controller=>“todos”}
DELETE /todos/:id(.:format)
{:action=>“destroy”, :controller=>“todos”}
tags GET /tags(.:format)
{:action=>“index”, :controller=>“tags”}
POST /tags(.:format)
{:action=>“create”, :controller=>“tags”}
new_tag GET /tags/new(.:format)
{:action=>“new”, :controller=>“tags”}

i already added
resources :todos do
member do
get ‘say_when’
end
end
now its print DELETE /tiptags/:id(.:format)
{:action=>“destroy”, :controller=>“tiptags”}
say_when_todo GET /todos/:id/say_when(.:format)
{:action=>“say_when”, :controller=>“todos”}
todos GET /todos(.:format)
{:action=>“index”, :controller=>“todos”}
POST /todos(.:format)
{:action=>“create”, :controller=>“todos”}
new_todo GET /todos/new(.:format)
{:action=>“new”, :controller=>“todos”}
edit_todo GET /todos/:id/edit(.:format)
{:action=>“edit”, :controller=>“todos”}
todo GET /todos/:id(.:format)
{:action=>“show”, :controller=>“todos”}
PUT /todos/:id(.:format)
{:action=>“update”, :controller=>“todos”}
DELETE /todos/:id(.:format)
{:action=>“destroy”, :controller=>“todos”}

The problem is that (by definition) this links to the show action for
a todo (the second argument to link_to specifies what the link should
point at) If you want it to link to something else, then, after you’ve
added it to routes.rb, you can write something like link_to ‘Say
when’, say_when_todo(todo), …
