Datastores : Mongoose

Mongoose is popular object modeling layer for MongoDB, an open source, document-oriented NoSQL database written in C++.

Adapter

locomotive-mongoose is a datastore adapter that adds Mongoose model awareness to Locomotive.

To use the Mongoose adapter, install it via npm and save it in package.json:

npm install locomotive-mongoose --save

Register it in config/environments/all.js:

this.datastore(require('locomotive-mongoose'));

Model Awareness

Mongoose documents can then be passed directly to urlFor():

Animal.findById(this.param('id'), function(err, animal) {
  if (err) { return next(err); }
  self.url = self.urlFor(animal);
  next();
});

Initializer

The following initializer, located at config/initializers/nn_mongoose.js will configure Mongoose and connect to MongoDB when starting a Locomotive application:

module.exports = function() {
  switch (this.env) {
    case 'development':
      mongoose.connect('mongodb://mongodb.example.com/dev');
      break;
    case 'production':
      mongoose.connect('mongodb://mongodb.example.com/prod');
      break;
  }

  mongoose.model('User', schemas.UserSchema);
  mongoose.model('Post', schemas.PostSchema);
}
