#update ⇒ Object

This is a multi-purpose method for processing logic related to changes in the Order. It is meant to be called from various observers so that the Order is aware of changes that affect totals and other values stored in the Order.

This method should never do anything to the Order that results in a save call on the object with callbacks (otherwise you will end up in an infinite recursion as the associations try to save and then in turn try to call update! again.)

  })

  run_hooks
end

#update_adjustments ⇒ Object

Updates each of the Order adjustments.

This is intended to be called from an Observer so that the Order can respond to external changes to LineItem, Shipment, other Adjustments, etc.

Adjustments will check if they are still eligible. Ineligible adjustments are preserved but not counted towards adjustment_total.

end

#update_payment_state ⇒ Object

Updates the payment_state attribute according to the following logic:

paid when payment_total is equal to total balance_due when payment_total is less than total credit_owed when payment_total is greater than total failed when most recent payment is in the failed state

The payment_state value helps with reporting, etc. since it provides a quick and easy way to locate Orders needing attention.

  else
    order.payment_state = 'paid'
  end

  order.state_changed('payment')
end

#update_shipment_state ⇒ Object

Updates the shipment_state attribute according to the following logic:

shipped when all Shipments are in the “shipped” state partial when at least one Shipment has a state of “shipped” and there is another Shipment with a state other than “shipped”

or there are InventoryUnits associated with the order that have a state of "sold" but are not associated with a Shipment.

ready when all Shipments are in the “ready” state backorder when there is backordered inventory associated with an order pending when all Shipments are in the “pending” state

The shipment_state value helps with reporting, etc. since it provides a quick and easy way to locate Orders needing attention.

#update_totals ⇒ Object

Updates the following Order total values:

payment_total The total value of all finalized Payments (NOTE: non-finalized Payments are excluded) item_total The total value of all LineItems adjustment_total The total value of all adjustments (promotions, credits, etc.) total The so-called “order total.” This is equivalent to item_total plus adjustment_total.
