ohm-find_by

This is just a fast implementation of AR find_by_{attr} for Ohm

class Post < Ohm::Model
  attribute :name
  attribute :author

  index :name
end

With that Ohm::Model in mind now you can do this:

Post.create :name => "My first Post", :author => "elCuervo"
=> #<Post:1 name="My first Post" author="elCuervo">
Post.find_by_name "My first Post"
=> #<Set (Post): ["1"]>

Also checks the existence of the index before searching so:

Post.find_by_author "elCuervo"
=> Ohm::Model::IndexNotFound

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
