title: Rails - wrong number of arguments(1 for 0) for a newly generated Rails app?
body: <p>I just setup a new rails app, and I uses <code>rails generate controller Pages</code> to create a blank page controller, then I added empty methods and views. I changed the route.rb to redirect to <code>pages/:action</code>, so it should display <code>foo.html.erb</code> for <code>pages/foo</code>. However, I have this error everytime I'm trying to access any of the page (<code>pages/</code>, <code>pages/index</code>, <code>pages/course</code>, etc.)</p>
  
  <p><strong>localhost:3000/pages/register</strong> (note: the actual <code>Rails.root</code> is different)</p>
  
  <pre><code>ArgumentError in PagesController#register
  wrong number of arguments(1 for 0)
  
  Rails.root: C:/railsapp
