zf2: मॉडल

Question

में सेवा लोकेटर कैसे प्राप्त करें मैंने अन्य पदों और उदाहरणों से कुछ विचारों की कोशिश की लेकिन मुझे अभी भी समाधान नहीं मिला है। मैं अपने मॉडल में servicelocator प्राप्त नहीं कर सकता।

लेकिन var_dump($this->getServiceLocator()); रिटर्न नल:

'Backend\Model\Beuser' => function($sm){ 
        $serviceLocator = $sm->getServiceLocator(); 
        return new \Backend\Model\Beuser($serviceLocator); 
       }, 

अपने मॉडल Beuser.php की तरह दिखता है:

मेरी Module.php समारोह getServiceConfig (में निम्नलिखित कारखाना) शामिल हैं। reasion क्यों $this->getServiceLocator()->get('something') के किसी भी कॉल एक PHP Fatal error: Call to a member function get()[...]

तुम मुझे समस्या खोजने में मदद कर सकते हैं बनाता है thats?

पुनश्च:

'Backend\Model\Beuser' => function($sm){ 
     $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter'); 
     $beuser = new \Backend\Model\Beuser(); 
     $beuser->setDbAdapter($dbAdapter);

Answer 1

आप इसे एक से कोई भी विद्यमान निर्माता के माध्यम से में से गुजर रहे हैं ... बस सेटर का उपयोग मैं भी कारखाने निम्नलिखित की कोशिश की। सेवा प्रबंधक ServiceLocatorInterface लागू करता है, बस इसे अपने मॉडल के माध्यम से पास करें।

'Backend\Model\Beuser' => function($sm){ 
    $model = new \Backend\Model\Beuser(); 
    $model->setServiceLocator($sm); 

    return $model; 
}, 

उदाहरण नियंत्रक में प्रवेश::

public function testAction() 
{ 
    // The service manager will then inject itself into your model 
    // when it is instantiated. 
    $myModel = $this->getServiceLocator()->get('Backend\Model\Beuser'); 

    // now you have the Service Locator injecte4d into your model .. 
    //var_dump($myModel->getServiceLocator()); 
} 

आपको यह भी सुनिश्चित उपयोग सेवा लोकेटर मॉडल आप आपके ज़रूरत से किसी उदाहरण पाने के लिए बनाने की जरूरत है, नहीं तो कुछ भी नहीं

आपकी सेवा config बदलें इंजेक्शन दिया जाएगा:

'BeuserTableGateway' => function ($sm) { 
    $dbAdapter = $sm->get('dbAdapter'); 
    $resultSetPrototype = new ResultSet(); 
    // Beuser will not have the service locator injected below.. 
    // and will return null if the object wasn't created via the service manager. 
    //$resultSetPrototype->setArrayObjectPrototype(clone $sm->get('Backend\Model\Beuser')); 
    $resultSetPrototype->setArrayObjectPrototype(new Beuser()); 

    return new TableGateway('tbl_be_user', $dbAdapter, null, $resultSetPrototype); 
}, 

Answer 2

धन्यवाद एंड्रयू - आपके उत्तरों में शू है मुझे सही तरीका है :-) मैंने अपनी समस्या हल की। मैं सेवा मॉडल द्वारा नियंत्रक में एल्बम मॉडल प्राप्त करना भूल गया।

नियंत्रक:

public function addAction(){ 
    [...] 
    //Adapter an Beuser Model uebergeben 
    $beuser->setDbAdapter($this->getServiceLocator()->get('dbAdapter')); 
    [...] 
} 

public function editAction(){ 
    [...] 
    //Adapter an Beuser Model uebergeben 
    $beuser->setDbAdapter($this->getServiceLocator()->get('dbAdapter')); 
    [...] 
} 

मॉडल:

private $adapter; 

public function setDbAdapter($dbAdapter) { 
    $this->adapter = $dbAdapter; 
} 

public function getDbAdapter() { 
    return $this->adapter;  
} 

और अब मैं मॉडल में एडाप्टर कॉल कर सकते हैं इस तरह से

$this->getDbAdapter();
