Class: Poro::ContextFactories::SingleStore::MongoFactory

Defined in:
lib/poro/context_factories/single_store/mongo_factory.rb

Overview

Creates a factory that generates MongoContext instances to the supplied database, automatically setting the data_store to point at the collection with the underscored, pluralized name of the class backing it.

One can further configure the Context in several ways:

  1. Supply a block to new.

  2. Configure in the model.

  3. Fetch the Context directly, though this is considered bad form.

Wichever method you choose, it is wise to be consistent throughout the application.

This factory does not allow complex behaviors such as database switching.
