Ok figured it out, the sessions_helper.rb needs to look like this:
module SessionsHelper
def sign_in(user)
cookies.permanent.signed[:remember_token] = [user.id, user.salt]
current_user = user
end
def current_user=(user)
@current_user = user
end
def current_user
@current_user ||= user_from_remember_token
end
def signed_in?
!current_user.nil?
end
def sign_out
cookies.delete(:remember_token)
self.current_user = nil
end
private
def user_from_remember_token
User.authenticate_with_salt(*remember_token)
end
def remember_token
cookies.signed[:remember_token] || [nil, nil]
end
end
