php - Symfony2 / FOSUserBundle: Change render variables in response without altering parent class -

one of classes extends basecontroller on fosuserbundle, , returns parent action. however, due project spec, shouldn't have need edit parent class. there way of sending additional variables, twig render, through child response?

child class:

class changepasswordcontroller extends basecontroller {     public function changepasswordaction(request $request)     {         $response = parent::changepasswordaction($request);          return $response; // , 'myvariable' => $myvariable     } } 

parent class:

class changepasswordcontroller extends containeraware {     /**      * change user password      */     public function changepasswordaction(request $request)     {         //lots of code.....          return $this->container->get('templating')                     ->renderresponse(                     'fosuserbundle:changepassword:changepassword.html.'                         .$this->container->getparameter('fos_user.template.engine'),                          array(                          'form' => $form->createview()                            //and 'myvariable' => $myvariable                                 )                );      } } 

so summarise, there way of passing parent class, without changing parent class... whilst rendering twig view additional variable.

-- update --

essentially want render form using fosuserbundle changepassword action, therefore works fine:

return $this->container             ->get('templating')             ->renderresponse(             'fosuserbundle:changepassword:changepassword.html.'.$this->container->getparameter('fos_user.template.engine'),             array('form' => $form->createview())         ); 

however, want pass more variables view, 'form' passed shown above, without altering fosuserbundle changepassword controller. therefore have class inherits controller, adds additional functionality , returns parent change password action:

class changepasscontroller extends changepasswordcontroller {     public function changepasswordaction(request $request)     {         // more code......          $response = parent::changepasswordaction($request);         return $response;     } } 

but, applications, want add more form variable view template. there way of passing additional variable view, without altering parent controller / action? (but not like) pushing 'myvariable' => $myvariable parent changepasswordaction return statement?

there section in fosuserbundle documentation describes how that, , symfony2's cookbook, how use bundle inheritance override parts of bundle.

in summary, create bundle class override fosuserbundle in src:

// src/acme/userbundle/acmeuserbundle.php <?php  namespace acme\userbundle;  use symfony\component\httpkernel\bundle\bundle;  class acmeuserbundle extends bundle {     public function getparent()     {         return 'fosuserbundle';     } } 

then, override changepasswordcontroller class:

use fos\userbundle\controller\changepasswordcontroller basecontroller;  class changepasswordcontroller extends basecontroller {     public function changepasswordaction(request $request)     {         $response = parent::changepasswordaction($request);          return $response; // , 'myvariable' => $myvariable     } } 

--update--

ok think misread question. anyway renderresponse() of templating service essentially:

$response->setcontent($this->render($view, $parameters)); 

you can see class of templating service running app/console container:debug twigengine class.

so can re-invoke renderresponse() , supply own parameters. eg:

return $this->container->get('templating')->renderresponse(     'fosuserbundle:changepassword:changepassword.html.'.$this->container->getparameter('fos_user.template.engine'),     array(         'form' => $form->createview(),         'myvariable' => $myvariable', // there go     ),     $response // previous response has been rendered parent class, not necessary );
