= TinyMongo

Simple MongoDB wrapper

== Notice

This gem is not yet ready for production use.

== Install

  gem install tinymongo

== Rails Setup (Rails 3)

To create TinyMongo config file (config/tinymongo.yml) and initializer file (config/initializers/tinymongo.rb), do the following:

  rails generate tinymongo

  

== Connecting To MongoDB directly (for non-Rails projects)

  TinyMongo.configure({:host => 'localhost', :database => 'db_name'})

  TinyMongo.connect

  

== Example

  class Person < TinyMongo::Model

    mongo_collection :people          # optional if using Rails

    mongo_key :name

    mongo_key :age, :default => 0

    mongo_key :children, :default => []

  

    def make_child

      child = Person.create(:name => 'Baby')

      push({:children => child})      # push child into children array

    end

  

    def grow_up

      inc({:age => 1})                # increments age by 1

    end

    

    def set_stuff(n,a,c)

      # don't forget to put self

      self.name = n

      self.age = a

      self.children = c

      save

    end

  end

  

  Person.drop                         # empty person collection

  

  p = Person.create(:name => 'John', :age => 20)

  p.make_child

  p.grow_up

  

  Person.find.each do |person|

    puts person.name

  end

  

  Person.find_one(:name => 'John').age

  

  Person.create(:name => 'Jim')

  Person.create(:name => 'Pam')

  Person.find.to_a.map { |person| person.name }

  

  Person.find.has_next?

  Person.find.sort({:name => 1}).skip(2).limit(1).next!.name 

  

  Person.find({:name => 'John'}, {:age => 1}) # select only age field

  

  Person.find.count # count ignores skip and limit

  Person.find.skip(1).size # size is affected by skip and limit

  

  Person.distinct(:name)

  

  Person.ensure_index({:name => 1})

  Person.drop_index({:name => 1})
