📂 Multiple User Scopes with Custom Sessions

When your app has multiple Devise models (e.g., User and Admin), isolate their sessions and routes to prevent conflicts and reuse controllers. Specify custom controllers and scope routes to customize behavior, redirects, and views per role.

# config/routes.rb
devise_for :admins,
           controllers: { sessions: 'admins/sessions' }

devise_for :users

# app/controllers/admins/sessions_controller.rb
class Admins::SessionsController < Devise::SessionsController
  # Redirect admins to dashboard
  def after_sign_in_path_for(resource)
    admin_dashboard_path
  end
end

Customize user sessions independently:

# app/controllers/users/sessions_controller.rb
class Users::SessionsController < Devise::SessionsController
  layout 'public'
end
