Question

I know that I can have a session after the user login. Also, I created a helper method called “current_user”. I don’t want to other people which are not signed in can get access to the page. Apart from making doing this, how can I do?

I can do this to not allow people the get access to the content, but I don’t want the user within login see the blank page too.

<% if current_user%>
My Content
<% end %>

Answer 1

Make a before_filter that checks if the current_user variable is set, and redirects the user to some other place (root, signup page, something) if it is not. Something like this:

class ApplicationController < ActionController::Base
  def login_required
    redirect_to('/') if current_user.blank?
  end
end

class MyController < ApplicationController
  before_filter :login_required, :only => :action_aviable_only_for_logged_in

  def action_aviable_only_for_logged_in
    ...
  end
end
