}

<?php echo $block->getFilterData(); ?>

Any help On this?

Answer 1

your collection class needs to be in the file Test/Learning/Model/ResourceModel/Learning/Collection.php and have the namespace namespace Test\Learning\Model\ResourceModel\Learning;

Answer 2

You have to keep below line in your function,

$data = $this->_learningFactory->create()->getCollection()->addFieldToFilter('customer_id', array('eq' => $customerId));
