redis_orm 0.6

I finally released redis_orm 0.6 gem. In this version:

added equality operator for object, #to_s method for inspecting objects, #find! which could throw RecordNotFound error

added self.descendants class method which returns all inherited from RedisOrm::Base classes

introduced :sortable option (in property declaration and #find conditions hash) - rudimentary ability to sort records by any property (not just by default 'created_at')

now handling models withing modules definitions (test for this in associations_test.rb)

properly handling :as parameter in options for :has_many/:belongs_to self-references

binding related models while creating model instance (like this: Article.create(:comment => comment))

bunch of small fixes, updated tests and README.md

File attachment management with paperclip and redis

If you recently migrated from the well known SQL-land to the terra incognita of key-value storages (in particular to Redis) and are now wondering how the hell you'll be handling all those avatars and photos users keep uploading to the servers, this small article is for you.

Things are much easier in case you are already using paperclip. Here are 3 steps you should follow to manage your file attachments with redis and paperclip:

1. Add "redis_orm" gem to your Gemfile:

gem "redis_orm", "~> 0.5"

2. Inherit your model with attachments from RedisOrm::Base class like this:

class User < RedisOrm::Base

  # here goes 4 specific to paperclip properties:

  property :avatar_file_name, String   property :avatar_content_type, String   property :avatar_file_size, Integer   property :avatar_updated_at, Time

  include Paperclip::Glue # here's the most tricky part (:

  has_attached_file :avatar, :styles => {:big => "900x900>", :medium => "200x200>", :chat => "42x42>"} end

3. my pull request to paperclip has been recently merged (w00t!), so before new gem is released you should pull it right from github:

gem "paperclip", :git => 'git://github.com/thoughtbot/paperclip.git'

And that's it! It just works.

All other code (e.g. on view and controller level) is specific to paperclip and could be found on their github page.
