title: Use Carrierwave with Active Admin
body: <p>Did any of you guys manage to get Active Admin with Carrierwave working?</p>
  
  <p>When I installed AA everything worked fine but the image file upload
  fields were plain text fields so added following:</p>
  
  <pre><code>ActiveAdmin.register Club do
    form do |f|
      f.inputs "Club" do
        f.input :league
        f.input :name
        f.input :image, :as =&gt; :file
        f.input :approved
      end
      f.buttons
    end
  end
  </code></pre>
  
  <p>Now it's displayed as a file upload field and I can select a file but
  after I submitted the form nothing changed. There's still no image and
  the image field is empty. Anyone knows what else to do to get it
  working?</p>
