Class Method Details

.evaluate_discount(user, join) ⇒ Object

User is the user that may have a discount for this entity. Join is the entity in which there is a setting for yes this user has a discount associated to them. We expect the join model to have a discount_tier column that is set to either. So we expect it to be set up this way:

  • Model Join - Attributes: user_id, discount_tier (optional column = entity_id (for discounting on)).

nil if there is no discount, or the discount tier if there is indeed one.
