メモ - Mongoid による MongoHQ へのアクセスの実験

Rails app への Mongoid 導入

ruby/rails で MongoDB を使うときのメジャーな選択肢として MongoMapper, Mongoid がありますが、

Mongoid の方が後発、
Mongoid の方が 2011/6 の段階で rails 3 対応、ドキュメントなどが充実しているらしいなどの理由により、 Mogoid を使います。 (あまり詳しく調べてませんが、問題が発生したら乗り換えることもそんなに難しくないはず)

	# I wrote this for Rails 3 beta 4 / Ruby 1.9.2-pre3.
	# This is a VERY nasty patch for work arounding rack's Encoding::BINARY (ASCII-8BIT) rack.input issue.
	# I don't know the RIGHT solution about the issue, but I have to fix:
	# Encoding::UndefinedConversionError ("\xE3" from ASCII-8BIT to UTF-8)
	# Sometime in the future, I hope this is no use...

	You know OCMock does great, but (If I'm not get wrong with it)
	- it will supposed to be used in tests not a production code
	- it can't mock class methods
	- it requires an instace to be mocked accessible in your tests

	If you not familiar with alias_method_chain, see:
