Defined in:
app/services/delivery/group_www_shipping_costs.rb

Overview

Groups a delivery's ShippingCost rows into the service-level buckets the
WWW shipping picker renders: :economy (the override placeholder),
:ground, :faster (expedited + rush), and :freight (cheapest only).
PO-box destinations are restricted to postal carriers; otherwise the store
country's WWW carrier list applies (its order breaks cost ties when
sort_by_price is off).

Extracted from Delivery#sorted_shipping_costs_www_hash (god-object
decomposition); the model keeps a thin delegator.

Examples:

Delivery::GroupWwwShippingCosts.new(delivery).process
Delivery::GroupWwwShippingCosts.new(delivery, sort_by_price: false).process

Constant Summary collapse

GROUND =

Ground = slower commitments; Speedee is always ground regardless of its
committed days. Uses shipping_option.days_commitment for categorization,
NOT sc.days_commitment, which includes dynamic carrier estimates that vary
by shipment.

->(sc) { sc.shipping_option.days_commitment >= 3.5 || sc.shipping_option.carrier == 'SpeedeeDelivery' }
EXPEDITED = 
->(sc) { sc.shipping_option.days_commitment >= 2 && sc.shipping_option.days_commitment < 3.5 && sc.shipping_option.carrier != 'SpeedeeDelivery' }
RUSH = 
->(sc) { sc.shipping_option.days_commitment < 2 && sc.shipping_option.carrier != 'SpeedeeDelivery' }
