#primary_key(name, type = :primary_key, options = {}) ⇒ Object

Crate doesn’t support auto incrementing, therefore we need to manually set a primary key. You need to assure that you always provide an unique id. This might be done via the SecureRandom.uuid method and a before_save callback, for instance.
