Class Method Details

.backordered_for_stock_item(stock_item) ⇒ Object

This was refactored from a simpler query because the previous implementation led to issues once users tried to modify the objects returned. That’s due to ActiveRecord ‘joins(shipment: :stock_location)` only returning readonly objects

Returns an array of backordered inventory units as per a given stock item
