Polymorphic Associations reversed

It's pretty easy to do polymorphic associations in Rails: A Picture can belong to either a BlogPost or an Article. But what if you need the relationship the other way around? A Picture, a Text and a Video can belong to an Article, and that article can find all media by calling @article.media

This example shows how to create an ArticleElement join model that handles the polymorphic relationship. To add fields that are common to all polymorphic models, add fields to the join model.

# Parses YouTube URLs directly or from iframe code.  Handles:
# * Address bar on YouTube url (ex: http://www.youtube.com/watch?v=ZFqlHhCNBOI)
# * Direct http://youtu.be/ url (ex: http://youtu.be/ZFqlHhCNBOI)
# * Full iframe embed code (ex: <iframe src="http://www.youtube.com/embed/ZFqlHhCNBOI">)
# * Old <object> tag embed code (ex: <object><param name="movie" value="http://www.youtube.com/v/ZFqlHhCNBOI">...)

/(youtu\.be\/|youtube\.com\/(watch\?(.*&)?v=|(embed|v)\/))([^\?&"'>]+)/
$5 #=> the video ID
