I am creating a simple frontend magento 2 module to take input from user and save output in database.

Here is what i have tried.

Index.php -- (Index controller index action)

namespace Companyname\Faq\Controller;
use Magento\Framework\App\RequestInterface;

class Index extends \Magento\Framework\App\Action\Action
    public function __construct(\Magento\Framework\App\Action\Context $context) {

     * Dispatch request
     * @param RequestInterface $request
     * @return \Magento\Framework\App\ResponseInterface
     * @throws \Magento\Framework\Exception\NotFoundException
    public function dispatch(RequestInterface $request) {
        return parent::dispatch($request);

Add.php -- (Index controller add action)


namespace Companyname\Faq\Controller\Index;

class Add extends \Companyname\Faq\Controller\Index {
    public function execute() {
    try {
        $params = $this->getRequest()->getPostValue();               

        $faq = $this->_objectManager->create('Companyname\Faq\Model\Faq');
    } catch (\Exception $e) {




namespace Companyname\Faq\Model;

class Faq extends \Magento\Framework\Model\AbstractModel {
    public function __construct() {


namespace Companyname\Faq\Model\Resource;

class Faq extends \Magento\Framework\Model\Resource\Db\AbstractDb {
    protected function _construct() {
    $this->_init('faq', 'faq_id');

i get post data properly and the model also loads correctly with this line - $this->_objectManager->create('Companyname\Faq\Model\Faq');

However, when it tries to save the data, an error gets generated. Fatal error: Call to a member function dispatch() on a non-object in \lib\internal\Magento\Framework\Model\AbstractModel.php on line 663

After a little debugging, i found that it is not getting eventManager inside \lib\internal\Magento\Framework\Model\AbstractModel.php in this line - $this->_eventManager->dispatch('model_load_before', $params);

Any clues as to what i am doing wrong ?

  • Looks like problem in Companyname\Faq\Model\Faq model. Can you show it?

  • @KAndy - i have updated the question to include Companyname\Faq\Model\Faq model Oct 16 '15 at 5:42

Problem in method __construct. You need to call _construct (one underlinen), not __construct, like

namespace Companyname\Faq\Model;

class Faq extends \Magento\Framework\Model\AbstractModel {
    public function _construct() {

I think we need to have better name for this "pseudo constructor" method

  • Do you clear cache and var/generation dirs? Still the same exception?
