validation - Rails 4 and Devise - routing issue with sign-up page -

i have routing question related devise.

i have model - member (rather user) , have custom routes

devise_for :members, controllers: {registrations 'members/registrations',                          omniauth_callbacks: 'members/omniauth_callbacks',                          sessions: 'members/sessions' } devise_scope :member   authenticated :member     root :to => 'home#index', as: :authenticated_root   end    unauthenticated :member     root :to => 'devise/sessions#new', as: :unauthenticated_root   end end 

my issue relates sign-up page when fails (due validation failing).

the displayed url is

http://localhost:3000/members/sign_up 

but if validation fails redirects

http://localhost:3000/members 

(this page show registration/new form , form works fine if input validates)

in contrast, on sign-in page

http://localhost:3000/members/sign_in 

if failing validation redirects itself

http://localhost:3000/members/sign_in 

now may wonder why asking this. have implementation of growly flash messages indicate validation failure. work on different devise views except sign-up one. routing difference difference can see between them. guessing if sign-up page redirected on failure, sign-in page flash messages work.

its odd question insights on routing/url behaviour in devise helpful.

registrations_controller.rb

  class members::registrationscontroller < devise::registrationscontroller    # /resource/sign_up     def new       build_resource({})       self.resource.user = user.new       respond_with self.resource     end    # post /resource    def create     super     resource.user.ip_address = request.remote_ip        unless resource.email.nil? || resource.email.empty?        resource.user.email = resource.email        resource.user.save     end   end    private     def sign_up_params     allow = [:provider, :uid, :email, :password, :password_confirmation, user_attributes: [:member_id, :email, :first_name, :last_name, :institution, :city, :country, :job_title, :about, :tag_list, :picture, :ip_address]]     params.require(resource_name).permit(allow)   end  end
