MongoSessionStore is a collection of Rails-compatible session stores for MongoMapper and Mongoid, but also included is a generic Mongo store that works with any (or no!) Mongo ODM.
MongoSessionStore is compatible with Rails 3.0, 3.1, and 3.2.
In your Gemfile:
gem "mongo_mapper" # or "Mongoid," or another Mongo ODM, or nothing
gem "mongo_session_store-rails3"In the session_store initializer (config/initializers/session_store.rb):
# MongoMapper
MyApp::Application.config.session_store :mongo_mapper_store
# Mongoid
MyApp::Application.config.session_store :mongoid_store
# anything else
MyApp::Application.config.session_store :mongo_store
MongoStore::Session.database = Mongo::Connection.new.db('my_app_development')Note: If you choose to use :mongo_store you only need to set its database if you aren't using MongoMapper or Mongoid in your project.
By default, the sessions will be stored in the "sessions" collection in MongoDB. If you want to use a different collection, you can set that in the initializer:
MongoSessionStore.collection_name = "client_sessions"And if for some reason you want to query your sessions:
# MongoMapper
MongoMapperStore::Session.where(:updated_at.gt => 2.days.ago)
# Mongoid
MongoidStore::Session.where(:updated_at.gt => 2.days.ago)
# Plain old Mongo
MongoStore::Session.where('updated_at' => { '$gt' => 2.days.ago })The following is the benchmark run with bson_ext installed. Without bson_ext, speeds are about 10x slower. The benchmark saves 2000 sessions (~12kb each) and then finds/reloads each one.

To run all the tests:
rake
To switch to the Gemfile.lock for a certain Rails version:
rake use_rails_30
rake use_rails_31
rake use_rails_32
To run the tests for a specific store:
MONGO_SESSION_STORE_ORM=mongo_mapper bundle exec rspec spec
MONGO_SESSION_STORE_ORM=mongoid bundle exec rspec spec
MONGO_SESSION_STORE_ORM=mongo bundle exec rspec spec
MongoSessionStore started as a fork of the DataMapper session store, modified to work with MongoMapper and Mongoid. Much thanks to all the previous contributors:
