/***********************************************************************************************************************************************************************
|
|
* File Name: purchasable.util.js
|
|
* Type of Program: Utility
|
|
* Description: Resolves a Product's polymorphic target (purchasable_type +
|
|
* purchasable_id → Course | Unit | Lesson) and the checkout
|
|
* route for it. Products.mdl.js can't express a single
|
|
* Sequelize association across three different target models,
|
|
* so this is the shared lookup every consumer (access checks,
|
|
* admin product CRUD, client checkout) goes through instead.
