How do I remove the Devise route to sign up?

Question

I\'m using Devise in a Rails 3 app, but in this case, a user must be created by an existing user, who determines what permissions he/she will have.

Because of this, I

I had similar issue tried to remove devise_invitable paths for create and new :

before:

 devise_for :users

rake routes

accept_user_invitation GET    /users/invitation/accept(.:format)           devise/invitations#edit
       user_invitation POST   /users/invitation(.:format)                  devise/invitations#create
   new_user_invitation GET    /users/invitation/new(.:format)              devise/invitations#new
                       PUT    /users/invitation(.:format)                  devise/invitations#update

after

devise_for :users , :skip => 'invitation'
devise_scope :user do
  get "/users/invitation/accept", :to => "devise/invitations#edit",   :as => 'accept_user_invitation'
  put "/users/invitation",        :to => "devise/invitations#update", :as => nil
end

rake routes

accept_user_invitation GET    /users/invitation/accept(.:format)                 devise/invitations#edit
                       PUT    /users/invitation(.:format)                        devise/invitations#update

note 1 devise scope https://github.com/plataformatec/devise#configuring-routes

note 2 I'm applying it on devise_invitable but it will work with any devise *able feature

Important note: see that devise_scope is on user not users ? that's correct, watch out for this ! It can cause lot of pain giving you this problem:

Started GET "/users/invitation/accept?invitation_token=xxxxxxx" for 127.0.0.1 
Processing by Devise::InvitationsController#edit as HTML
  Parameters: {"invitation_token"=>"6Fy5CgFHtjWfjsCyr3hG"}
 [Devise] Could not find devise mapping for path "/users/invitation/accept?  invitation_token=6Fy5CgFHtjWfjsCyr3hG".
This may happen for two reasons:

1) You forgot to wrap your route inside the scope block. For example:

  devise_scope :user do
     match "/some/route" => "some_devise_controller"
  end

 2) You are testing a Devise controller bypassing the router.
   If so, you can explicitly tell Devise which mapping to use:

    @request.env["devise.mapping"] = Devise.mappings[:user]
