    respond_to do |format|       format.html # index.html.erb       format.xml { render :xml => @todos }     end   end

  # GET /todos/1   # GET /todos/1.xml   def show     @todo = Todo.find(params[:id])

    respond_to do |format|       format.html # show.html.erb       format.xml { render :xml => @todo }     end   end

  # POST /todos   # POST /todos.xml   def create     @todo = Todo.new(params[:todo])

    respond_to do |format|       if @todo.save         format.html { redirect_to(@todo, :notice => 'Todo was successfully created.') }         format.xml { render :xml => @todo, :status => :created, :location => @todo }       else         format.html { render :action => "new" }         format.xml { render :xml => @todo.errors, :status => :unprocessable_entity }       end     end   end

  # PUT /todos/1   # PUT /todos/1.xml   def update     @todo = Todo.find(params[:id])

    respond_to do |format|       if @todo.update_attributes(params[:todo])         format.html { redirect_to(@todo, :notice => 'Todo was successfully updated.') }         format.xml { head :ok }       else         format.html { render :action => "edit" }         format.xml { render :xml => @todo.errors, :status => :unprocessable_entity }       end     end   end

  # DELETE /todos/1   # DELETE /todos/1.xml   def destroy     @todo = Todo.find(params[:id])     @todo.destroy

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"}

but the same happens

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), ...
