Sequel by default does not use proxies for associations. The association method for *_to_many associations returns an array, and the association_dataset method returns a dataset. This plugin makes the association method return a proxy that will load the association and call a method on the association array if sent an array method, and otherwise send the method to the association's dataset.
Usage:
# Use association proxies in all model subclasses (called before loading subclasses) Sequel::Model.plugin :association_proxies # Use association proxies in a specific model subclass Album.plugin :association_proxies
