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.

# Ruby-like syntax in AR conditions using the underlying Arel layer (Rails >= 3.0).

# What you would usually write like this: 
#
#   User.where(["users.created_at > ? AND users.name LIKE ?", Date.yesterday, "Mary"])
#
# can now be written like this (note those parentheses required by the operators precedences):

Start XCode and create a new Storyboard file. I closed all my other XCode projects. When you choose the location of the created file, it should be your RubyMotion project's resources directory. Add a UIViewController, and set it's identifier property to "Start". Add some UI elements so you can see it working.

When you run rake in your RubyMotion project, it will compile the .storyboard file. You could auto-load the Storyboard using a plist configuration, but you'll see code can do it too.
