DataMapper::Ambition is a plugin that provides an Ambition-like API for
accessing DataMapper models.

== Installation

With Rubygems:

  $ gem install dm-ambition
  $ irb -rubygems
  >> require 'dm-ambition'
  => true

With git and local working copy:

  $ git clone git://github.com/dkubb/dm-ambition.git
  $ cd dm-ambition
  $ rake install
  $ irb -rubygems
  >> require 'dm-ambition'
  => true

== Testing

The simplest way to test is with Bundler since it handles all dependencies:

  $ rake local_gemfile
  $ BUNDLE_GEMFILE="Gemfile.local" ADAPTER="in_memory" bundle install --without=quality --relock
  $ BUNDLE_GEMFILE="Gemfile.local" ADAPTER="in_memory" bundle exec rake spec

== Examples

    # with == operator
    User.select { |u| u.name == 'Dan Kubb' }

    # with =~ operator
    User.select { |u| u.name =~ /Dan Kubb/ }

    # with > operator
    User.select { |u| u.id > 1 }

    # with >= operator
    User.select { |u| u.id >= 1 }

    # with < operator
    User.select { |u| u.id < 1 }

    # with <= operator
    User.select { |u| u.id <= 1 }

    # with < operator
    User.select { |u| u.id < 1 }

    # with receiver.attribute.nil?
    User.select { |u| u.id.nil? }

    # with nil bind value
    User.select { |u| u.id == nil }

    # with true bind value
    User.select { |u| u.admin == true }

    # with false bind value
    User.select { |u| u.admin == false }

    # with AND conditions
    User.select { |u| u.id == 1 && u.name == 'Dan Kubb' }

    # with negated conditions
    User.select { |u| !(u.id == 1) }

    # with double-negated conditions
    User.select { |u| !(!(u.id == 1)) }

    # with matching from receiver
    User.select { |u| u == user }

    # with matching to receiver
    User.select { |u| user == u }

    # using send on receiver
    User.select { |u| u.send(:name) == 'Dan Kubb' }

    # with Array#include?
    User.select { |u| user_ids.include?(u.id) }

    # with Range#include?
    User.select { |u| (1..10).include?(u.id) }

    # with Hash#key?
    User.select { |u| { 1 => 'Dan Kubb' }.key?(u.id) }

    # with Hash#value?
    User.select { |u| { 'Dan Kubb' => 1 }.value?(u.id) }

    # with receiver and Array#include?
    User.select { |u| users.include?(u) }

    # with receiver and Hash#key?
    User.select { |u| { user => 'Dan Kubb' }.key?(u) }

    # with receiver and Hash#value?
    User.select { |u| { 'Dan Kubb' => user }.value?(u) }
