AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>

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.

Your app/widgets directory can get crazy pretty fast. If you're learning Apotomo, then you'll probably move things around and try many ways to order your widgets directory. This is not so much about that - I still haven't found a good way to organize my widgets, but I've found a way to keep the widget classes themselves DRY.

Create an ApplicationWidget just like Rails' ApplicationController

And it should look something like this:

# A BaseWidget to apply stuff to widgets across
# the board. All widgets should inherit from this
class ApplicationWidget < Apotomo::Widget

include ActionController::RecordIdentifier # so I can use dom_id
