I have two custom modules and am calling one collectionfactory in other module and getting `

Call to undefined method addAttributeToSelect

Collection file look like

 class Collection extends MagentoFrameworkModelResourceModelDbCollectionAbstractCollection

 /**
 * Initialize resource collection
 *
 * @return void
 */
 public function _construct()
 
 $this->_init('VendorModuleModelHello', 'VendorModuleModelResourceModelHello');
 

and am calling in block

use VendorModuleModelResourceModelHelloCollectionFactory; 

 class Custom extends MagentoBackendBlockWidgetGridExtended
 
 public function __construct(
 CollectionFactory $collectionFactory,
 array $data = 
 ) 

 $this->collectionFactory = $collectionFactory;
 parent::__construct($context, $backendHelper, $data);
 

 protected function _prepareCollection()
 
 $collection = $this->collectionFactory->create();
 $collection->addAttributeToSelect('*');
 $this->setCollection($collection);
 return parent::_prepareCollection();
 

 

Getting PHP Fatal error: Uncaught Error: Call to undefined method
VendorModuleModelResourceModelHelloCollection::addAttributeToSelect()

You have to replace addAttributeToSelect('*') with addFieldToSelect('*')

addAttributeToFilter() is used to filter EAV collections.

addFieldToFilter() is used to filter Non-EAV collections.

Try with

$collection->addFieldToSelect('*');

which is exist under

MagentoFrameworkModelResourceModelDbCollectionAbstractCollection

and

addAttributeToSelect

method exist under

MagentoEavModelEntityCollectionAbstractCollection

so you need to create module with EAV.
