Rails Devise: How to access sign up page after signed in?

问题

I am new with rails and i am using "devise" gem for authentication purposes.

At first i add a new user through default sign up page (E.g./users/sign_up)

Then, i made "sign_up" page only available to signed_in users by following instructions from

Devise before filter that prevents access to "new_user_registration_path" unless user is signed-in

Now, after sign in process when i try open sign up page it always directs me to root_path! How can i access sign up page?
My "roots.rb" file as follows:

Example::Application.routes.draw do

  devise_for :users, :controllers => { :registrations => 'registrations'}

  resources :companies

  resources :orders

  resources :customers

  root :to => "welcome#index"

end

Thank you all!

The way I handled the scenario of being able to create New Users if you are signed in was by generating a User controller and having new and create action methods that would save to the User model. (This was stripped from a current app I'm working on so hopefully I didn't miss anything)

user_controller.rb

def new
  @user = User.new
end

def create
  @user = User.new(params[:user])

  if @user.save
    flash[:notice] = "Successfully created User." 
    redirect_to root_path
  else
    render :action => 'new'
  end
end

views/user/new.html.erb

<%= form_for @user, :url => user_index_path do |f| %>
  <p><%= f.label :email %>
  <%= f.text_field :email %></p>

  <p><%= f.label :password  %>
  <%= f.password_field :password %></p>

  <p><%= f.label :password_confirmation  %>
  <%= f.password_field :password_confirmation %></p>

  <p><%= f.submit "Save" %></p>
<% end %>

config/routes.rb (Rails 3)

resources :user, :controller => "user"

Link to the New User page

<%= link_to 'New User', new_user_path %>

I have other decision. Bitterzoet said

As you can see in the devise source if you navigate to the sign_up it executes the before_filter require_no_authentication and this redirects to the root path which you can find here.

You don't need override registration_controller, you can change only your custom registration_controller that echo original registration_controller.

class Admin::RegistrationsController < Devise::RegistrationsController
  layout 'admin'
  prepend_before_filter :require_no_authentication, :only => []
  prepend_before_filter :authenticate_scope!
end

If you are getting redirected it probably means you are not properly authenticated when you navigate to that page, seeing as it requires a valid user session.

Please post your Registrations controller file as well.

I think you will have to explicitly override the registrations_controller that I linked first if you really want to override this behaviour :-)
