Do you think we are missing an alternative of MongoModel or a related project?
MongoModel is a Ruby ORM for interfacing with MongoDB databases.
MongoModel is distributed as a gem. Install with:
gem install mongomodel
For performance, you should probably also install the BSON C extensions:
gem install bson_ext
Using with Rails
Add MongoModel to your Gemfile (and run
Create the configuration file
rails generate mongo_model:config DATABASENAME
Generating a model/document:
rails generate model Article title:string body:string published_at:time approved:boolean
Generating an embedded document:
rails generate model Chapter title:string body:string -E
class Article < MongoModel::Document property :title, String, :default => 'Untitled' property :body, String property :published_at, Time, :protected => true property :approved, Boolean, :default => false, :protected => true timestamps! validates_presence_of :title, :body belongs_to :author, :class => User scope :published, where(:published_at.ne => nil) end
MongoModel can be configured similarly to ActiveRecord by creating/editing
config/mongomodel.yml. The most basic configuration might look like:
development: database: mymongodbname host: localhost port: 27017
The config file also supports specifying the username, password, pool_size, password and replicas. Running
rails generate mongo_model:config DATABASENAME will generate a basic config file for you.
Using Replica Sets
When working with replica sets, replace the host/port configuration with an array of replicas (
production: database: database_name replicas: - some.host.com:27017 - another.host.com:27017 username: username password: password
