"How do I create a model without a backing store?"

One way to do this is to use the active-form plugin (or here), which lets you create model objects that support ActiveRecord Validations but are not backed by database table. Not to be confused with the other ActiveForm, which is a DSL for defining XHTML forms with validation.

"How do I turn an association into an array?"

You can access the underlying array by using .target or .proxy_target. If you want to cause the association to load all it's data pass any parameter, for example

blog = Blog.find(:first)
posts = blog.posts(:force_load)

• AWS gems log spew and SSL

Noticed that when using the RightScale Amazon Web Services gem that a lot of log output is going to STDOUT. To capture this output specify a logger wherever you create your AWS service object, for example:

development:

RightAws::S3.new(access_key, secret_key, :logger => Logger.new(File.join(File.dirname(__FILE__), '..', '..', 'aws_sqs.log'), 'daily'))

demo/production:

RightAws::S3.new(access_key, secret_key, :logger => Logger.new(File.join(File.dirname(__FILE__), '..', '..', 'aws_sqs.log'), 'monthly'))

To prevent even more warnings from appearing in your log output you can also set the @http.verify_mode as follows:

original:

      @http.use_ssl = true
      ca_file = get_param(:ca_file)
      if ca_file
        @http.verify_mode = OpenSSL::SSL::VERIFY_PEER
        @http.verify_callback = verifyCallbackProc
        @http.ca_file = ca_file
      end

patched:

      @http.use_ssl = true
      ca_file = get_param(:ca_file)
      if ca_file
        @http.verify_mode = OpenSSL::SSL::VERIFY_PEER
        @http.verify_callback = verifyCallbackProc
        @http.ca_file = ca_file
      else
        @http.verify_mode = OpenSSL::SSL::VERIFY_NONE
      end
