How to use RESTful routes.

Okay, this has come up before... but it is NOT working for me *sigh* but, I'm hoping someone can tell me why. (Rails version 1.2.6)

Let's say I want to create an off the wall method in my Users controller, called login. I also create the view for this action, login.erb. My first problem was that /users/login did not work (rails mistook login for being :id). So that was fixed with:

  map.resources :users, :collection => {:login => :get }

But now, I want my users to be able to click login from the homepage, simple enough? But this RESTful link generates a no method error.

<%= link_to 'Login', login_users_path %>

What have I missed/why does this not work?

$ rake routes

Do I have to run that? Does that change any files that I can just upload themselves? I can't just go around raking things on my shared host...

rake routes just help you figure out what is available.
