How to Remove/Disable Sign Up From Devise - ruby-on-rails

Question

I'm trying to remove/disable the user/sign_up path from Devise. I'm doing this because I don't want random people gaining access to the application. I have it partly working by adding the following in routes.rb
Rails.application.routes.draw do
devise_scope :user do
get "/sign_in" => "devise/sessions#new" # custom path to login/sign_in
get "/sign_up" => "devise/registrations#new", as: "new_user_registration" # custom path to sign_up/registration
end
...
devise_for :users, :skip => :registration
end
However, this breaks <%= link_to "Profile", edit_user_registration_path, class: "btn btn-info btn-flat" %>
which I want to keep so that users can update their profile.
I know it's because of the devise_for :users, :skip => :registration
Is there a solution for this issue?
Running
Devise (4.2.0, 4.1.1, 4.1.0)
Rails 4.2.5
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]

Answer 1

The easiest way is just removing :registerable devise module from the default list defined into your Model (the class name used for the application’s users, usually User).
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
...
end
So you'll have it like this:
class User < ActiveRecord::Base
devise :database_authenticatable,
:recoverable, :rememberable, :trackable, :validatable
...
end

Solution to removing sign_up path from Devise
Enter the following at the beginning of routes.rb
Rails.application.routes.draw do
devise_scope :user do
get "/sign_in" => "devise/sessions#new" # custom path to login/sign_in
get "/sign_up" => "devise/registrations#new", as: "new_user_registration" # custom path to sign_up/registration
end
...After the statement above, add the following below in routes.rb
devise_for :users, :skip => [:registrations]
as :user do
get 'users/edit' => 'devise/registrations#edit', :as => 'edit_user_registration'
put 'users' => 'devise/registrations#update', :as => 'user_registration'
end
This will remove/disable the user/sign_up path for Devise without breaking edit_user_registration_path
Restart your rails server and it should work.

I just had the same issue. My solution is a mix of these answers.
Comment out or remove :registerable in user.rb:
class User < ActiveRecord::Base
devise :database_authenticatable, #:registerable,
:recoverable, :rememberable, :trackable, :validatable
end
Remove the registration paths from devise_for in routes.rb:
devise_for :users, :skip => [:registrations], controllers: {
sessions: 'users/sessions'
}
Now Devise will skip all of the registration links from their view and also you no longer have the registration paths on your routes.

Redirecting from controller
I solved this issue by redirecting /sign_up to /sign_in from the controller, while preserving the functionality of editing user info. For instance:
In controllers/users/registrations_controller.rb
# GET /resource/sign_up
def new
redirect_to new_user_session_path and return
super
end
In routes.rb, I pointed registrations resource to this controller:
devise_for :users, controllers: {
sessions: 'users/sessions',
registrations: 'users/registrations'
}
So whenever users visit route /sign_up, it'll redirect them to /sign_in. Just remember to use and return after the redirection to prevent multiple render/redirect

Since as is just an alias for devise_scope, you can put all that in just one block.
devise_for :users, skip: [:registrations]
as :user do
get "/sign_in" => "devise/sessions#new" # custom path to login/sign_in
get "/sign_up" => "devise/registrations#new", as: "new_user_registration" # custom path to sign_up/registration
get 'users/edit' => 'devise/registrations#edit', :as => 'edit_user_registration'
put 'users' => 'devise/registrations#update', :as => 'user_registration'
end

Below code seem to do the trick for me:
Rails.application.routes.draw do
devise_scope :users do #notice "users" here, not "user"
get "/sign_in" => "devise/sessions#new" # custom path to login/sign_in
get "/sign_up" => "devise/registrations#new", as: "new_user_registration" # custom path to sign_up/registration
end
devise_for :users, :skip => [:registrations]
as :user do
get 'users/edit' => 'devise/registrations#edit', :as => 'edit_user_registration'
put 'users' => 'devise/registrations#update', :as => 'user_registration'
end
...
