error with devise in ruby on rails

So, I have never used devise before and am trying to implement it in my program via http://railscasts.com/episodes/209-introducing-devise. I installed it and everything word for word as this guy did and then when I try and go to http://localhost:3000/users/sign_up, I get this error:

 Routing Error

 No route matches [GET] "/users/sign_up"

here is what I get when I do rake route:

new_user_session GET    /users/sign_in(.:format)              {:action=>"new", :controller=>"devise/sessions"}

If you watch the video the guy is just able to go to that web address and it just works. I noticed that there is a [GET] /users/registration/sign_up(.:format) but no [GET] /users/sign_up like the guy in the video has. Is there something I am missing?

p.s.

this is the error I get when I try to go to one of the routes listed above (user/sign_in):

 NoMethodError in Devise/registrations#new
 Showing /Users/davidfleischhauer/.rvm/gems/ruby-1.9.2-p290/gems/devise- 1.1.rc0/app/views/devise/registrations/new.html.erb where line #3 raised:

 undefined method `user_registration_path' for #<#<Class:0x007f85eafec758>:0x007f85eaf77ed0>

---

You have to use new_user_registration_path in order to create a link to the sign up page. You have to use new_user_session_path in order to create a link to sign_in.

---

Bear in mind the video is a year+ old :)

If you look at the current devise source where the routes are generated you'll see that it apparently no longer creates a "sign_up" route--looks like the registration paths are the current method.

It also looks like you're using a release candidate version, which always makes me a little nervous, since that's a release candidate and not necessarily 100% stable--which might explain why the default template is using a path variable that doesn't exist.

---

I am trying to figure out why you are using Devise version 1.1rc0 and not the latest gem available which is 1.4.7? I have several applications all running this latest version in which the sign_up path works just fine. I would recommend updating to the latest version of the gem and try again. Outside of that, I can only think of problems that could be caused by something in your routes.rb file or if you are trying to override the Devise Registrations Controller.

add to routes.rb this is:

devise_for :users do

  get'users/sign_out'=>'devise/sessions#destroy'

end

it's for sign_out

for sign_up go to config/initializers/secret_token.rb and copy line: config.secret_token ='...' and paste it in config/aplication.rb
