With commerce api module, you can fetch all available shipping methods of an order with a GET request on {{host}}/jsonapi/checkout/{{cart_uuid}}/shipping-methods. Result is something like this:
{
"type": "shipping-rate-option",
"id": "3--default",
"attributes": {
"shipping_method_id": "3",
"service": {
"id": "default",
"label": "Pickup at location"
},
"original_amount": {
"number": "0",
"currency_code": "CZK",
"formatted": "0,00 Kč"
},
"amount": {
"number": "0",
"currency_code": "CZK",
"formatted": "0,00 Kč"
},
"description": "",
"delivery_date": null
}
},
I would like to add a custom field to each shipping method.
Following this tutorial, I tried to create a computed field, like this:
function custom_module_entity_base_field_info(EntityTypeInterface $entity_type) {
if ($entity_type->id() === 'commerce_shipment') { // also tried 'shipping_rate_option'
$fields['tooltip'] = BaseFieldDefinition::create('string')
->setLabel(t('tooltip'))
->setReadOnly(TRUE)
->setComputed(TRUE)
->setClass(FieldTooltip::class);
return $fields;
}
}
And my class is
/**
* Class FieldTooltip.
*/
class FieldTooltip extends FieldItemList {
use ComputedItemListTrait;
/**
* {@inheritdoc}
*/
protected function computeValue() {
$this->list[0] = $this->createItem(0, 'tooltip text');
}
}
It did nothing.
Also tried to create a normalizer, but that didn't do any change either.
Is there a way to add a field to this response?
