Check if an order has been refunded in a template? What’s the best way to check if an order has been refunded in a template?

For example, you may want to: 


Add a message to the order/invoice template if a refund has been successful.
Determine the status of the refund; perhaps displaying a different message if the status is not yet success.
Show the time of refund.
You get the related transactions for an order with

order.transactions

So you can loop over the transactions like so:

{% for transaction in order.transactions %}
  {{ transaction.type|title }}
  {{ transaction.status|title }}
  {{ transaction.amount|currency(transaction.currency) }} ({{ transaction.currency }})
  {{ transaction.paymentMethod.name }}
  {{ transaction.dateUpdated|date }} // could also format to get the time
{% endfor %}


The transaction 'type' column can hold the following values:

authorize, capture, purchase, refund

The transaction 'status' column can hold the following values:

pending, direct, success, failed

Some of those transaction types have a 'parent' transaction, for example, if you authorized a credit card, you would have a authorize transaction. When you capture that authorization you get a capture transactions whose parent is the authorize transaction.

{{ transaction.type }} // could return 'refund'
{% set parent = transaction.parent %}
{{ parent.type }} // could return 'purchase' or 'capture'
