php - Symfony Doctrine: Remove all ManyToMany relations -


i have manytomany relationship between 2 entities (clientproject & tour) working except 1 case. when want clear relations between entities, doesn't work , database not updated accordingly.

clientproject.php

/**  * @orm\manytomany(targetentity="tour", inversedby="clientprojects")  * @orm\jointable(  *  name="client_projects_tour_items",  *  joincolumns={  *      @orm\joincolumn(name="client_project_id", referencedcolumnname="id")  *  },  *  inversejoincolumns={  *      @orm\joincolumn(name="tour_id", referencedcolumnname="id")  *  }  *  )  */  protected $touritems;   public function removetouritem(\sharedbundle\entity\tour $touritem) {     $this->touritems->removeelement($touritem); }

tour.php

public function removeclientproject(\sharedbundle\entity\clientproject $clientproject) {     $this->clientprojects->removeelement($clientproject); }

working example:

  1. before update:
    • tour 1 / clientproject 3
    • tour 1 / clientproject 4
  2. action: remove relation between tour 1 , clientproject 4
  3. after update:
    • tour 1 / clientproject 3

failing example:

  1. before update:
    • tour 1 / clientproject 3
  2. action: remove relation between tour 1 , clientproject 3
  3. after update:
    • tour 1 / clientproject 3

controller action

public function editclientprojectaction($id, request $request) { if (!$request->isxmlhttprequest()) {    return $this->redirecttoroute('contact'); }  $clientproject = $this->getdoctrine()->getrepository(clientproject::class)->find($id); if(!$clientproject) {     return new jsonresponse(array('redirect' => $this->generateurl('contacts'))); }  $form = $this->createform(clientprojectformtype::class, $clientproject, array(     'action' => $this->generateurl('edit-client-project', array('id' => $id)) )); $form->setdata($clientproject); if ($request->ismethod('post')) {     $form->submit($request->request->get($form->getname()), false);     if($form->issubmitted() && $form->isvalid()) {         $em = $this->getdoctrine()->getmanager();         $em->persist($clientproject);         $em->flush();           return new jsonresponse(array('reloaddatatable' => 'client_project_datatable'));     } else {         return new jsonresponse(array('reload' => true));     } }  return $this->render('@appbundle/client-projects/edit-client-project.html.twig', [     'form' => $form->createview(), ]); }

in order make remove work, think need add code remove methods:

# entity/clientproject.php /**  * remove touritem  *  * @param \sharedbundle\entity\tour $touritem  */ public function removetouritem(\sharedbundle\entity\tour $touritem) {     if (!$this->touritems->contains($touritem)) {         return;     }     $this->touritems->removeelement($touritem);     $clientproject->removetouritem($this); }  # entity/tour.php /**  * remove clientproject  *  * @param \sharedbundle\entity\clientproject $clientproject  */ public function removeclientproject(\sharedbundle\entity\clientproject $clientproject) {     if (!$this->clientproject->contains($clientproject)) {         return;     }     $this->clientprojects->removeelement($clientproject);     $touritem->removeclientproject($this); }

also, in tour.php file need add annotation:

cascade={"persist", "remove"}

when set relation.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
