How do I remove the Devise route to sign up?

Question

you can do this in your model

# typical devise setup in User.rb
devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable

change it to:

devise :database_authenticatable, :recoverable, :rememberable, :trackable, :validatable

notice that the symbol :registerable was removed

That's it, nothing else is required. All routes and links to registration page are magically removed too.

I tried to do this as well, but a thread on the devise google group dissuaded me from searching for a really clean solution.

I'll quote José Valim (the Devise maintainer) :

There isn't a straight-forward option. You can either provide a patch or use :skip => :registerable and add only the routes you want.

The original question was :

Is there any good way to remove a specific route (the delete route) from Rails?

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]

I found another post similar to this one and wanted to share an answer @chrisnicola gave. In the post they were attempting to only block user signup's during production.

You could also modify the registrations controller. You can use something like this:

In "app/controllers/registrations_controller.rb"

class RegistrationsController < Devise::RegistrationsController
  def new
    flash[:info] = 'Registrations are not open.'
    redirect_to root_path
  end

  def create
    flash[:info] = 'Registrations are not open.'
    redirect_to root_path
  end
end

This will override devise's controller and use the above methods instead. They added flash messages incase that someone somehow made it to the sign_up page. You should also be able to change the redirect to any path you like.

Also in "config/routes.rb" you can add this:

devise_for :users, :controllers => { :registrations => "registrations" }

Leaving it like this will allow you to use the standard devise edit your profile. If you wish you can still override the edit profile option by including

  def update
  end

in the "app/controllers/registrations_controller.rb"
