Rails devise redirecting to '/users' instead of '/users/sign_up' on failed registration

Question

I've been searching all over to fix this - when a user fails a registration create using Devise, for whatever reason they get redirected to '/users' instead of staying on '/users/sign_up' and persisting the errors:

Here are my routes:

devise_for :users, controllers: {
  sessions:       'users/sessions',
  confirmations:  'users/confirmations',
  registrations:  'users/registrations',
  passwords:      'users/passwords',
  invitations:    'users/invitations'
}, sign_out_via: [:get, :delete]

And /users/registrations_controller.rb

class Users::RegistrationsController < Devise::RegistrationsController
  prepend_before_filter :require_no_authentication, only: [:new, :create]

  def new
    @body_class = "hold-transition register-page"
    build_resource({})
    yield resource if block_given?
    respond_with resource
  end

  def create
    build_resource(sign_up_params)
    resource.save
    yield resource if block_given?
    if resource.persisted?
      if resource.active_for_authentication?
        set_flash_message :notice, :signed_up if is_flashing_format?
        sign_in(resource_name, resource)
        respond_with resource, location: after_sign_up_path_for(resource)
      else
        set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_flashing_format?
        expire_data_after_sign_in!
        respond_with resource, location: after_inactive_sign_up_path_for(resource)
      end
    else
      clean_up_passwords resource
      render :new
    end
  end
end

If the resource is not persisted, in the spot where it says render :new I've tried the following:

redirect_to new_user_registration_path(resource) - does not persist errors

render :new - routes to '/users' but does persist errors

respond_with resource - does same as :new

respond_with resource, location: new_user_registration_path(resource) - again same as above

So if the resource doesn't persist how can I get it to just go back to the same page - '/users/sign_up' and persist the errors? I've seen some very hacky ways but there's no way Devise doesn't offer a solution for this instead of forcing it to route to '/users'. I've also seen solutions that include a redirect and setting a flash - this is not something I want to do, I'd rather the errors persist in the form.

Thanks a lot

From reading your question, im assuming you want to go back if registration fails?

you can use:

redirect_to :back

And in your code like this:

else
  clean_up_passwords resource
  render :new
  redirect_to :back
end
