# If you have a hash or an array or something that quacks like one, you can do stuff
# example:
# h = {a: {b: {c: [{d: 'hi'}]}}}
# h.extend(DotNotation)
# h.dot('a.b.c.0.d')
# #=> 'hi'
# h.dot('a.b.c.foo.bar.bz.whatever.124.whocares')

MongoMapper to give EmbeddedDocument a "delete" method
View embedded_document_delete.rb
# MongoMapper "embedded document delete" plugin
# By Peter Cooper
#
# Got embedded documents you want to delete? You can delete them as if the
# embedded document collection were an array, but then there's no way to get
# a callback (as far as I could tell). This plugin gives you a call back
# (if you want it) and gives a nicer syntax to deleting embedded docs.

Feedback on Ember `VIEW_PRESERVES_CONTEXT`
View Feedback.md

After a mind numbing week of updating all of the templates in our app and thinking about the implications of this change, I'd like to provide a little bit of feedback on this change.

Overall, I view this change as unfavorable. It's not that I dislike the change, it's that I don't find much value in it and it was a very daunting task to push to Ember users.

Template Simplification

From what I've gathered the purpose of this change is to "significantly reduce the verbosity of templates". I did not find that my templates either grew or shrank in size, they really remained constant. I believe one of the intended ways for reducing size was the elimination for the need of contentBinding="this" on {{view}} helpers. E.g.

{{#each App.photosController}}
