[Boulder Ruby Group] rendering now!

[Bruce Williams]

Ara,
The filter needs to return false to stop the action dispatch.

Here's a working example (just played with it):

--snip--
class FoosController < ApplicationController

  before_filter :authenticate

  def index
    # won't get here
  end

  #######
  private
  #######

  def can_find_account # stub, use some method that's useful
    return false
  end

  def authenticate
    unless can_find_account
      render :template => 'shared/access_denied'
      return false
    end
  end

end
--snip--

I generally like rendering directly vs redirection in these cases.

Cheers,
Bruce
