RubyAMF-1.2 folks.

With so many requests for respond_to/format.amf functionality, I’m supporting it. Here is an example of using it in a class:

def MyController < ActionController::Base
  def list
    respond_to do |format|
     format.amf { render :amf => User.find(:all) }
    end
  end
end

You also need to declare a new mime type in the rails/config/envirionment.rb file (towards the end of the file). Like so:

Mime::Type.register "application/x-amf", :amf
