Handy little class for attaching arbitrary media files (images, audio, video, etc.) to events in a timeline application. It does a couple of nifty things for supporting the varying media types:

The before_post_process method ensures we attempt to generate thumbnails only for images.

The named scopes along with the set_item_type callback gives us a way to pull out media items of a certain type, without having to go down the often more-trouble-than-it's-worth STI path.

Is it just me, or is it crazy that directly saving a model created via #build or #new on a has_many :through relationship does not create a join model?

See the migrations.rb, models.rb & test_irb_session.txt files below for a concise example of the problem.

This kind of technique is used commonly on nested controllers, and it would work fine for a plain belongs_to or has_many associations. In fact, this behaviour would stop me from using any RESTful controller helpers, like resource_controller.

Is there are way to make it work? Or do I need to look for alternatives, like the below?
