# When an RSpec test like this fails,
# 
#   @my_array.should == [@some_model, @some_model2]
# 
# RSpec will call inspect on each of the objects to "help" you figure out
# what went wrong. Well, inspect will usually dump a TON OF SHIT and make trying
# to figure out why `@my_array` is not made up of `@some_model` and `@some_model2`.
#
# This little module and technique helps get around that. It will redefine `inspect`
# if you include it in your model object.

This is a little trick I use to spin up the packages instalation on Debian/Ubuntu boxes in Vagrant.

I add a simple function that checks if a directory named something similar to ~/.vagrant.d/cache/apt/opscode-ubuntu-12.04/partial (it may have another path in Windows or MacOS) and create the directory if it doesn't already exist.

def local_cache(basebox_name)
  cache_dir = Vagrant::Environment.new.home_path.join('cache', 'apt', basebox_name)
  partial_dir = cache_dir.join('partial')
  partial_dir.mkdir unless partial_dir.exist?
 cache_dir
