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

Answer 1

For others in my case.
With devise (3.5.2).
I successfully removed the routes to signup, but kept the ones to edit the profile, with the following code.

#routes.rb
devise_for :users, skip: [:registrations]
as :user do
  get 'users/edit' => 'devise/registrations#edit', :as => 'edit_user_registration'
  put '/users(.:format)' => 'devise/registrations#update', as: 'user_registration'
  patch '/users(.:format)' => 'devise/registrations#update'
end

Here's the slightly different route I went. It makes it so you don't have to override the devise/shared/_links.html.erb view.

In app/models/user.rb:

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

In config/routes.rb:

devise_for :users
devise_scope :user do
  put 'users' => 'devise/registrations#update', as: 'user_registration'
  get 'users/edit' => 'devise/registrations#edit', as: 'edit_user_registration'
  delete 'users' => 'devise/registrations#destroy', as: 'registration'
end

Before:

$ rake routes | grep devise
           new_user_session GET    /users/sign_in(.:format)                    devise/sessions#new
               user_session POST   /users/sign_in(.:format)                    devise/sessions#create
       destroy_user_session DELETE /users/sign_out(.:format)                   devise/sessions#destroy
              user_password POST   /users/password(.:format)                   devise/passwords#create
          new_user_password GET    /users/password/new(.:format)               devise/passwords#new
         edit_user_password GET    /users/password/edit(.:format)              devise/passwords#edit
                            PATCH  /users/password(.:format)                   devise/passwords#update
                            PUT    /users/password(.:format)                   devise/passwords#update
   cancel_user_registration GET    /users/cancel(.:format)                     devise/registrations#cancel
          user_registration POST   /users(.:format)                            devise/registrations#create
      new_user_registration GET    /users/sign_up(.:format)                    devise/registrations#new
     edit_user_registration GET    /users/edit(.:format)                       devise/registrations#edit
                            PATCH  /users(.:format)                            devise/registrations#update
                            PUT    /users(.:format)                            devise/registrations#update
                            DELETE /users(.:format)                            devise/registrations#destroy

After:

$ rake routes | grep devise
           new_user_session GET    /users/sign_in(.:format)                    devise/sessions#new
               user_session POST   /users/sign_in(.:format)                    devise/sessions#create
       destroy_user_session DELETE /users/sign_out(.:format)                   devise/sessions#destroy
              user_password POST   /users/password(.:format)                   devise/passwords#create
          new_user_password GET    /users/password/new(.:format)               devise/passwords#new
         edit_user_password GET    /users/password/edit(.:format)              devise/passwords#edit
                            PATCH  /users/password(.:format)                   devise/passwords#update
                            PUT    /users/password(.:format)                   devise/passwords#update
          user_registration PUT    /users(.:format)                            devise/registrations#update
     edit_user_registration GET    /users/edit(.:format)                       devise/registrations#edit
               registration DELETE /users(.:format)                            devise/registrations#destroy

Answer 3

Instead of searching for a hard solution. I used the below approaches.

1. Delete the sign_up form from page (path devise/registrations/new.html.erb) and replace it with custom info.

2. Redirect the incoming traffic to some other page. Like below in routes.rb

    get "/users/sign_up", to: redirect('/')

    post "/users/sign_up", to: redirect('/')

Make sure to write it before devise_for :users
