devise in rails 3 : 'user_signed_in?' false 'signed_in?' true 'current_user' nil -

i migrating rails 2 app rails 3 , had use new authentication solution since restful_authentication no longer supported. trying out devise , having problems it.

i have login page, directs app. can use app without logging in options not available until login.

once logging in devise says have logged in via flash message, current_user evaluate nil, current_user.blank? evaluates true , user_signed_in? evaluate false. oddly signed_in? evaluates true. checking session data shows warden.user.user.id contains correct user id , csrf token exists. true both in view , in controller.

here routes.rb

myapp::application.routes.draw    devise_for :users    match "/:controller(/:action(/:id))"     match "/:controller(/:action(/:id))(.:format)"   match "/:controller(/:action(.:format))"  devise_scope :user  'signup', :to => 'devise/registrations#new'  'login', :to => 'devise/sessions#new'  'signout', :to => 'devise/sessions#destroy' end     root :to => 'main#design'  end 

user.rb

require 'digest/sha1'  class user < activerecord::base    devise :database_authenticatable, :registerable,          :recoverable, :rememberable, :trackable, :confirmable, :validatable,          :encryptable, :encryptor => :restful_authentication_sha1    attr_accessible :email, :password, :password_confirmation, :remember_me, :profile_company, :profile_state, :profile_city, :profile_postcode, :profile_country, :profile_phone, :profile_address    validates_length_of       :name,     :maximum => 100       validates_presence_of     :email   validates_length_of       :email,    :within => 6..100   validates_uniqueness_of   :email     def profile_complete?     if !(self.profile_address.blank? || self.profile_city.blank? || self.profile_state.blank? || self.profile_phone.blank? || self.name.blank? || self.state != 'active')       true     else       false     end   end  end 

i've seen lot of similar questions on so, none of answers seem fit scenario. appreciated, thanks!

edit: warden.authenticate(:scope => :user) returns expect current_user return.

i believe have solved issue, restful_authentication plugin added usershelper file believe somehow interfering how devise handling user class.
