ServiceModule::Base
Defined in:
app/services/spree/carts/upsert_items.rb

Overview

Bulk upsert line items on a cart.

For each entry in items:

  • If a line item for the variant already exists -> sets its quantity

  • If no line item exists -> creates one with the given quantity

After all items are processed the cart is recalculated once.

Examples:

Spree::Carts::UpsertItems.new.call(
  cart: cart,
  items: [
    { variant_id: "variant_k5nR8xLq", quantity: 2 },
    { variant_id: "variant_m3Rp9wXz", quantity: 1 }
  ]
)
