Rails Authenticity Tokens and Facebooker

In case you’re working through Developing Facebook Platform Applications with Rails, you might have run into problems with authenticity tokens and FBML forms.  Quick dumb fix to save you 2 seconds:

<fb:fbml>
  <fb:request-form
    action="<%= new_invitation_path %>"
    method="POST"
    invite="true"
    type="Karate Poke"
    content="YAYS I added this facebbok app">
    <fb:multi-friend-selector
      showborder="false"
      actiontext="Invite your friends to use Karate Poke"
    />
    <%= hidden_field_tag :authenticity_token, form_authenticity_token %>
  </fb:request-form>
</fb:fbml>
