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…

Accepted Answer

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.
