Overview

Note:

this model uses paranoia. #destroy will only soft-destroy records and the default scope hides soft-destroyed records using WHERE deleted_at IS NULL.

Products represent an entity for sale in a store. Products can have variations, called variants. Product properties include description, permalink, availability, shipping category, etc. that do not change by variant.
