Class Method Details

.eligible_variants(variant, options = {}) ⇒ Object

This can be configured in an initializer, e.g.: Spree::ReturnItem::ExchangeVariantEligibility::SameOptionValue.option_type_restrictions = [“size”, “color”]

This restriction causes only variants that share the same option value for the specified option types to be returned. e.g.:

option_type_restrictions = [“color”, “waist”] Variant: blue pants with 32 waist and 30 inseam

can be exchanged for: blue pants with 32 waist and 31 inseam

cannot be exchanged for: green pants with 32 waist and 30 inseam blue pants with 34 waist and 32 inseam
