How to get credit memo collection from last 2 weeks in magento2

Question

I see that Magento\Sales\Model\Order\CreditmemoFactory has createByOrder and createByInvoice methods and I cannot do ->create()->addAttributeToFilter('created_at'

I would like to get the credit memos from the last 2 weeks regardless of when the order was placed. So I cannot do $order->getCreditmemosCollection().

Any ideas?

Thanks!

Answer 1

If I'm understanding your question correctly, you want to load all credit memos created in the last 2 weeks, regardless of when the order was created. Have you looked at using the service contracts for loading your data?

You'd need to inject the following 2 classes into your constructor. The SearchCriteriaBuilder class for creating the search criteria (filter), and the CreditmemoRepositoryInterface for loading the credit memos.

\Magento\Sales\Api\CreditmemoRepositoryInterface
\Magento\Framework\Api\SearchCriteriaBuilder

Build up your search criteria:

$yourDate = '2017-01-01';
$searchCriteria = $this->searchCriteriaBuilder
    ->addFilter(
        'created_at',
        $yourDate,
        'gt'
    )->create()
;

Then get the credit memos from the repository:

$creditmemos = $this->creditmemoRepository
    ->getList($searchCriteria)
    ->getItems()
;

From there you should be able to loop through the array, loading whatever data it is that you need:

foreach ($creditmemos as $creditmemo) {
    echo $creditmemo->getAdjustment();
}

You can see the available methods to call on the $creditmemo in the class \Magento\Sales\Api\Data\CreditmemoInterface.

Answer 2

You can include only \Magento\Sales\Model\ResourceModel\Order\Creditmemo\Collection in your constructor, in this case, you can use directly "addFieldToFilter" function without declaring or include searchCriteria

Your construct

public function __construct(
    ...
    \Magento\Sales\Model\ResourceModel\Order\Creditmemo\Collection $creditmemoCollection,
    ...
) {
    ...
    $this->creditmemoCollection = $creditmemoCollection;
    ...
}

And your function

public function yourfunction() {
    ...
    $collection = $this->creditmemoCollection;
    $collection->addFieldToFilter('created_at', array('gt' => $yourdate));

    foreach($collection as $creditmemo):
        ...
        $data = $creditmemo->getData();
        ....
    endforeach;
}
