Devise - Sign in On Subdomain

Question

I am using devise gem in a rails application with multiple subdomains and multiple schema.

Each subdomain is handled by controller, which look like this on application_controller.rb :

def load_subdomain
    @account = Account.find_by_subdomain!(request.subdomain)
end

def after_sign_in_path_for(resource)
    #admin login in domain
    if resource.is_a?(admin) 
      admin_path
    #user login in subdomain
    elsif resource.is_a?(user)
      subdomain_root_path
    else
      super
    end    
  end

on routes.rb

    match '/' => 'subdomains#index', :constraints => { :subdomain => /.+/ }, :as => :subdomain_root

devise_for :users, :skip => [:sessions, :registrations]

  devise_scope :user do
    get '/login/user' => 'sesusers#new', :as => :new_session_user
    post '/signin/user' => 'sesusers#create', :as => :user_session
    delete '/logout/user' => 'sesusers#destroy', :as => :destroy_user_session
    post '/send/user' => 'passwordusers#create', :as => :passwordusers_create
    get '/change_password/user' => 'passwordusers#edit', :as => :passwordusers_edit
    put '/change/user' =>  'passwordusers#update', :as => :passwordusers_update
  end

This leads to having multiple sign_in urls for each sub-domains.

subdomain1.lvh.me:3000/login/user
subdomain2.lvh.me:3000/login/user
subdomain3.lvh.me:3000/login/user
...
...
etc

on sesusers_controller.rb

class SesusersController < Devise::SessionsController
  include Tenantable::Schema::Controller
  before_filter :load_subdomain

  def new
    super
  end

  def create
    logger.info "Logged in"
    super
  end

  def destroy
    logger.info "Logout success"
    super
  end
end

When I try login, success login and redirect to subdomain_root_path

                <ul class="dropdown-menu">

                </ul>
         <% else %>
            <%= link_to ('<i class="icon-lock icon-white"></i>').html_safe + " Login" +(' <span class="caret"></span>').html_safe , '#', { :class => 'btn btn-danger dropdown-toggle', 'data-toggle' => 'dropdown' } %>

                </ul>
         <% end %>
    </div>
</div>

But on view subdomain current_user.name not display, appears only login button.

can someone help me?

thanks/

Answer 1

You just need to share the user session between the subdomain for this, so that one session can be continued with multiple subdomains.

You should modify the session_store.rb file in initializes as,

  DemoApp::Application.config.session_store :cookie_store, key: '_jcrop_app_session', domain: ".maindomain.com"

Adding the domain will work and careful with the last leading "." (period) which is needed for sub domain.
