DataMapper Mongo Adapter¶ ↑

github.com/solnic/dm-mongo-adapter/tree/master

WARNING¶ ↑

This adapter is a work-in-progress, so stay tuned :)

TODO¶ ↑

Embedded Objects¶ ↑

I have no idea. I'd guess a DM::Relationship#has hack or custom DM::Types that behave like a table-less resource?

Associations¶ ↑

The documentation for Mongo is confusing so I'm not sure if DBRef's are deprecated or not.

Query Performance¶ ↑

At the moment a single Javascript $where clause is built. Your indexes probably won't be used. A mixture of Hash conditions plus a Javascript $where clause when required would be much better.

Dependencies¶ ↑

Ruby

dm-core ~> 0.10.2
mongo ~> 0.18

Install¶ ↑

Via git:

git clone git://github.com/solnic/dm-mongo-adapter.git
rake install

Synopsis¶ ↑

DataMapper.setup(:default,
  :adapter  => 'mongo',
  :database => 'my_mongo_db',
)

# Define your DataMapper resource and start saving:
class User
  include DataMapper::Resource
  property :_id, ObjectID, :key => true
  property :name, String
  property :age, Integer
end

# No need to (auto_)migrate!
User.create(:name => 'Fred', :age => '25')

# Conditions:
users = User.all(:age.gte => 10, :limit => 20, :order => [:age.asc])
