holy shit! the capitalized underscore _ID is a column name! gonna use: `.underscore.camelcase` for an easy win; see: http://api.rubyonrails.org/classes/String.html#method-i-camelize
irb(main):016:0> "cool_id".camelcase
=> "CoolId"
irb(main):017:0> "cool_id".camelcase(:lower)
=> "coolId"
irb(main):018:0> "ServerID".underscore
=> "server_id"
irb(main):019:0> "ServerID".underscore.camelcase(:lower)
=> "serverId"
irb(main):020:0> "ServerID".camelcase(:lower)
=> "serverID"

# How To Get A List of All Registered Mime Types in Rails
# When mime types are registered they are placed in a hash constant
# EXTENSION_LOOKUP in the module Mime. For reference, the file with
# the relevant code is in rails/action_pack/lib/action_dispatch/http/mime_type.rb available
# on Github at https://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/http/mime_type.rb
#
# You can check for existence of certain mime types with
Mime::Type.lookup_by_extension(:json)

RocketAMF can de/serialize AMF serialized byte streams, but it throws (at least, the 0.2.1 version from gem install throws) when it encounters an IExternalizable type in the byte steam. This patch allows it to parsed custom IExternalizable classes properly.
#!/usr/bin/env ruby
require 'rocketamf'
require 'stringio'
# Monkey patch for RocketAMF (0.2.1 gem) that handles IExrternalizable types
# in the input, storing their type as "__as3_type" parameter:
module RocketAMF
