symfony - Adding a custom form inside the show template of a Sonata Admin Entity -

i want generate small form indide sonata admin show template. have done far creating function in custom crud specific entity (order) extends sonata's default crud;

public function approveorderaction($id = null) {     $request = $this->getrequest();      $id = $request->get($this->admin->getidparameter());     $order = $this->admin->getobject($id);      $approveform = $this->createformbuilder($order)         ->add('reqsecondapprover', 'checkbox', array('label' => 'require second approval', 'required' => false))         ->add('secondapprover', 'choice', array('choices' => crud::getwhatever(array('developer')), 'required' => false))         ->getform();      $approveform->handlerequest($request);      if ($approveform->issubmitted() && $approveform->isvalid()) {         $secondapproval = $request->request->get('form');         $approval = $approveform->getdata();          if (isset($secondapproval['reqsecondapprover'])) {             $order->setstatus(pmodorder::status_partly_approved);         } else {             $order->setstatus(pmodorder::status_approved);             $order->setsecondapprover(null);         }             $em->persist($approval);         $em->flush();          return new redirectresponse($this->admin->generateurl('show'));     }      return $this->render('appbundle:pmodorder:order_approve.html.twig', array(         'order' => $order,         'form' => $approveform->createview(),     )); } 

in orderadmin have configshowfields method;

protected function configureshowfields(showmapper $showmapper) {     $order = $this->getsubject();      $showmapper         ->with('general')             ->add('createdby', null, array('label' => 'requested by'))             ->add('createdat', null, array('label' => 'date requested'))         ->with('order details')             ->add('orderrows', null, array('template' => 'appbundle:pmodorderrow:orderrow_overview.html.twig'))         ->end()         ->with('actions')             ->add('actions', null, array('template' => 'appbundle:pmodorderaction:order_actions.html.twig', 'route' => 'approve'))         ->end()     ; } 

the order_actions template looks , show relevant functionality according status of order , logged in, how work many diffent routes?;

<td>     {% if app.user.id == object.firstapprover , object.status == 1%}         {{ render(controller('appbundle:pmodordercrud:approveorder', { 'id': object.id })) }}     {% elseif app.user.id == object.secondapprover , object.status == 2 %}         <a href="{{ path('order_second_approve', { 'id': object.id })}}" class="btn btn-primary"><i class="fa fa-check"></i> approve</a>         <a href="{{ path('order_disapprove', { 'id': object.id })}}" class="btn btn-default"><i class="fa fa-times"></i> disapprove</a>     {% elseif app.user == object.createdby , object.status == 3 %}         <a href="{{ path('order_place', { 'id': object.id })}}" class="btn btn-primary">place order</a>         <a href="{{ path('order_place', { 'id': object.id })}}" class="btn btn-default">cancel order</a>     {% else %}         -     {% endif %} </td> 

when trying error;

an exception has been thrown during rendering of template ("there no _sonata_admin defined controller apbundle\controller\pmodordercrudcontroller , current route ``") in appbundle:pmodorderaction:order_actions.html.twig @ line 3.

i understand documentation need make use of configureroutes method;

protected function configureroutes(routecollection $collection) {     $collection->add('clone', $this->getrouteridparameter().'/clone'); } 

but can't work , not sure how render forms instead of simple link button.

can please me fix problem?

the _sonata_admin (route) attribute used sonataadminbundle obtain required admin instance ($this->admin) , able configure/process request:

after add right route definition:

protected function configureroutes(routecollection $collection) {     $collection->add('approve_order', $this->getrouteridparameter().'/approve'); } 

you need add _sonata_admin code generate right request approveorderaction():

{{ render(controller('qibssfrontendbundle:pmodordercrud:approveorder', { 'id': object.id, '_sonata_admin': '...' })) }} 

let's make simple example:

you have order entity , admin class: orderadmin purchasebundle, sonata's service definition orderadmin class (yaml):

services:     purchase_bundle.admin.order_admin:         class: purchasebundle\admin\orderadmin         arguments:             - ~             - purchasebundle\entity\order             - ~         tags:             - { name: 'sonata.admin', manager_type: orm } 

now, based on own approveorderaction(), can render action in follows way:

{{ render(controller('purchasebundle:orderadmin:approveorder', { 'id': object.id, '_sonata_admin': 'purchase_bundle.admin.order_admin' })) }} 

just have add admin code: 'purchase_bundle.admin.order_admin' , should work!
