Reverse polymorphic associations in Rails

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.

class ApplicationController < ActionController::Base
...
#Problem:
#In rails 3.0.1+ it is no longer possible to do this anymore;
# rescue_from ActionController::RoutingError, :with => :render_not_found
#
#The ActionController::RoutingError thrown is not caught by rescue_from.
#The alternative is to to set a catch-all route to catch all unmatched routes and send them to a method which renders an error
#As in http://techoctave.com/c7/posts/36-rails-3-0-rescue-from-routing-error-solution

How to update VirtualBox Guest Additions with vagrant
# Start the old vagrant
$ vagrant init centos-6.3
$ vagrant up
# You should see a message like:
# [default] The guest additions on this VM do not match the install version of
# VirtualBox! This may cause things such as forwarded ports, shared
# folders, and more to not work properly. If any of those things fail on
# this machine, please update the guest additions and repackage the
# box.
