I have this code

$collection = Mage::getModel("news/views");
->addFieldToSelect('post_id', array('eq' =>  $this->getRequest()->getParam("id")));

And when i'm trying to save my post i get en error:

Invalid method Iv_News_Model_Views::addFieldToSelect(Array ( [0] => post_id [1] => Array ( [eq] => 13 ) ) )


The addFieldToSelect is available for collection objects. It is defined in Mage_Core_Model_Resource_Db_Collection_Abstract so it is available in all its child classes.

You are calling it on a model object that most probably is a child of Mage_Core_Model_Abstract.

I think you meant to do this:

$collection = Mage::getModel("news/views")->getCollection()
            ->addFieldToSelect('post_id', array('eq' =>  $this->getRequest()->getParam("id")));
  • it gets Fatal error: Call to a member function addFieldToSelect() on a non-object – user3245106 Apr 25 '14 at 8:17
  • This means that you module is not properly built. For a CRUD module you need a model, a resource model and a collection model. Most probably you are missing the collection mode. – Marius Apr 25 '14 at 8:19
  • Ok i figure it out that i have file Collections.php insted of Collection.php. What a rookie mistake. Thanks Marius. – user3245106 Apr 25 '14 at 8:48
  • One more question. Can I delete such collection ? – user3245106 Apr 25 '14 at 8:51
