yapper

RubyMotion ORM for the wonderful YapDatabase. Key features:

• Schemaless (define fields in your models)
• Very fast (thanks to YapDatabase's architecture)
• Chainable criteria
• One-many relationships
• On-the-fly reindexing
• Thread safe

Show me

  class User
    include Yapper::Document

    field :name,  :type => String
    field :email, :type => String
    field :bio,   :type => String

    has_many :locations

    index :name, :email
  end

  class Location
    include Yapper::Document

    belongs_to :user

    field :address
    field :city

    index :city
  end

  # Create
  user = User.create(:name => 'John Malkovich')
  location = Location.create(:user => user, :address => 'One Main', :city => 'Brooklyn')

  # Update
  user.update_attributes(:email => 'john@malkovich.com')

  # Wait for a document to exist
  User.when(id) { |user| puts "Got #{user.name}" }

  # Query (note you can only query on indexed fields)
  User.where(:email => 'john@malkovich.com')

  # Return all documents
  User.all

  # Chain queries
  User.where(:email => 'john@malkovich.com').where(:name => "John")

  # Count
  User.count
  User.where(:email => 'john@malkovich.com').where(:name => "John").count

  # Limit
  User.where(:email => 'john@malkovich.com').where(:name => "John").limit(1)

  # First
  User.where(:email => 'john@malkovich.com').where(:name => "John").first

  # Last
  User.where(:email => 'john@malkovich.com').where(:name => "John").last

  # On relations
  user.locations.where(:city => 'Brooklyn').first

See the specs for more detail.

Status

Beta. There are a lot of features missing that you'll probably want. Open an Issue or better yet create a pull request and let's make this happen.

Current roadmap:

• Performance optimizations (using a read-only connection on the main thread)
• Richer querying (not, or, custom sql)
• Views
• Full-text search
• RESTful API support
