ruby on rails - Session variable not accessible across controllers -

-

i ror beginner , trying implement basic google-openid (using omniauth-openid) authentication in ror app. here code snippets:

sessions_controller.rb:

class sessionscontroller < applicationcontroller   def create     user = user.from_omniauth(env["omniauth.auth"])     session[:user_id] = user.id     session[:my] = 'some'     puts "session[:user_id] = ", session[:user_id]     puts "session[:my] = ", session[:my]     redirect_to root_url   end end

routes:

photobucket::application.routes.draw   "welcome/index"   match 'auth/:provider/callback', to: 'sessions#create', via: [:get, :post]   match 'auth/failure', to: redirect('/'), via: [:get, :post]   match 'signout', to: 'sessions#destroy', as: 'signout', via: [:get, :post]

application controller:

class applicationcontroller < actioncontroller::base   # prevent csrf attacks raising exception.   # apis, may want use :null_session instead.   protect_from_forgery    private   def current_user     @current_user = user.find(session[:user_id])    end    helper_method :current_user end

template:

<div id="user-widget">   <%= current_user %> </div>

here's how log looks when person signs_in website:

so, session variable populated in session controller not accessible in application controller.
