I want to return my holders of a card with query builder and OneToMany relationship.
I have a problem with Semantical Error:
Error: Invalid PathExpression. StateFieldPathExpression or SingleValuedAssociationField expected.
return $this->getCardRepository()
->createQueryBuilder('c')
->leftJoin('Entity\CardHolder', 'ch', 'c.id = ch.id')
->where('ch.cards = :cards')
->setParameter('cardHolder', '%'.$card.'%')
->orderBy('ch.id', 'desc')
->getQuery()
->getResult();
And in my entities:
class Card
{
/**
* #ManyToOne(targetEntity="LaunchPad\Base\Entity\Card\CardHolder",)
* #JoinColumn(name="holder_id", referencedColumnName="id", nullable=true)
*/
private $cardHolder;
}
And second entity:
class CardHolder
{
public function __construct()
{
$this->cards = new ArrayCollection();
}
/**
* #var
*
* #OneToMany(targetEntity="Entity\Card", mappedBy="cardHolder")
*/
protected $cards;
}

I have two entities Product and Part, connected by a many-to-many relationship.
class Part
{
/**

*
* #ORM\ManyToMany(targetEntity="AppBundle\Entity\Product",
mappedBy="parts", fetch="EAGER")
*/
private $products;
public function __construct()
{
$this->products = new ArrayCollection();
}
/**

{
return $this->products;
}
}

{
/**

*

* #ORM\JoinTable(name="products_parts",
* joinColumns={
* #ORM\JoinColumn(name="product_id", referencedColumnName="id")
* },
* inverseJoinColumns={
* #ORM\JoinColumn(name="part_id", referencedColumnName="id")
* }
* )
*/
private $parts;
public function __construct()
{
$this->parts = new ArrayCollection();
}
/**

*/
public function getParts()
{
return $this->parts;
}
/**
* #param $parts
*/
public function setParts($parts)
{
$this->parts = $parts;
}
}
When I try get single Product and show all related parts. Symfony returns an empty array. Although the data is correctly added to the database. Where did I go wrong?
I have a self referencing entity with parent and children. The strange thing is, when I add the form elements (DoctrineModule ObjectSelect) for parent and children to the form, some other fields of the parent entity doesn't update, when I persist the entity. The child entities are updating fine.
In the update query of the parent aren't these fields which I want to update. It's like doctrine doesn't recognize the changes for the parent (owning side) anymore. Before the persist I get the right entity with the actual changes from the form, but than doctrine doesn't update the changed fields in the query.
When I delete the form elements for parent and children in the form, everything works fine and the parent entity update/persist all fields.

Answer based (and might still change) based on discussion in comments with OP under question.
Simple use case: self-referencing Doctrine Entity does not correctly update parent/child related Entity object properties on on-save action.
OP provided Entity.
I'm assuming you have a Form setup for this Entity. I'm also assuming it's correctly setup, as you did not provide it after being asked (because, rightly so, it would mean a lot of code). However, assuming stuff with code makes for a lot of mistakes, which is why I mention it here.
As such, I'm assuming the handling of your Form in the Controller might be faulty. To check, please use the following simplified addAction function and give it a shot (Factory code below).
/**
* #var RentalForm
*/
protected $form;
/**
* #var ObjectManager
*/
protected $objectManager;
public function __construct(ObjectManager $objectManager, RentalForm $form)
{
$this->form = $form;
$this->objectManager = $objectManager;
}
public function addAction()
{
/** #var RentalForm $form */
$form = $this->getForm();
/** #var Request $request */
$request = $this->getRequest();
if ($request->isPost()) {
$form->setData($request->getPost());
if ($form->isValid()) {
$entity = $form->getObject();
$this->getObjectManager()->persist($entity);
try {
$this->getObjectManager()->flush();
} catch (\Exception $e) {
$message = sprintf(
'Was unable to save the data. Saving threw an error. <br />Code: %s. <br />Message: %s',
$e->getCode(),
$e->getMessage()
);
$this->flashMessenger()->addErrorMessage($message);
return [
'form' => $form,
'validationMessages' => $form->getMessages() ?: '',
];
}
$this->flashMessenger()->addSuccessMessage(
$this->getTranslator()->translate('Successfully created object.')
);
// TODO replace vars with your own: return $this->redirect()->route($route, $routeParams);
}
$this->flashMessenger()->addWarningMessage(
'Your form contains errors. Please correct them and try again.'
);
}
return [
'form' => $form,
'validationMessages' => $form->getMessages() ?: '',
];
}
Factory for class with the above, modify as needed for you situation
class RentalControllerFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
/** #var ObjectManager $objectManager */
$objectManager = $container->get(EntityManager::class);
/** #var FormElementManagerV3Polyfill $formElementManager */
$formElementManager = $container->get('FormElementManager');
/** #var RentalForm $form */
$form = $formElementManager->get(RentalForm::class);
return new RentalController($objectManager, $form);
}
}
I would like to have the relationship between 2 tables, with OneToMany and ManyToOne relationships.
Survey
id
title
Questions:
id
survey_id
So i am looking to list the surveys and their respective questions, so how can i achieve that.
Here is my code,
Survey Entity:
<?php
namespace Survey\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Library\Entity\BaseEntity;
/**
* Description of Survey
*
* #author Mubarak
*/
/**
* #ORM\Entity
* #ORM\Table(name="surveys")
*/
class Survey extends BaseEntity{
public function __construct() {
$this->questions = new ArrayCollection();
}
/**
* #ORM\Column(name="title", type="string")
* #var string
*/
protected $title;
/**
* #ORM\Column(name="description", type="string")
* #var string
*/
protected $description;
/**
* #ORM\OneToMany(targetEntity="Survey\Entity\Questions", mappedBy="surveys")
*/
private $questions;
public function getTitle() {
return $this->title;
}
public function setTitle($title) {
$this->title = $title;
}
public function getDescription() {
return $this->description;
}
public function setDescription($description) {
$this->description = $description;
return $this;
}
public function getQuestions() {
return $this->questions;
}
public function setQuestions(ArrayCollection $questions) {
$this->questions = $questions;
}
public function __toString() {
return __CLASS__ . ": [id: {$this->id}, name: {$this->name}]";
}
}
Below is the Questions Entity:
<?php
namespace Survey\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Library\Entity\BaseEntity;
/**
* Description of Survey Questions
*
* #author Mubarak
*/
/**
* #ORM\Entity
* #ORM\Table(name="survey_questions")
*/
class Questions extends BaseEntity{
/**
* #ORM\Column(name="question", type="string")
* #var string
*/
protected $question;
/**
* #ORM\ManyToOne(targetEntity="Survey\Entity\Survey", inversedBy="questions")
* #ORM\JoinColumn(name="survey_id", referencedColumnName="id")
*/
private $surveys;
public function getQuestion() {
return $this->question;
}
public function setQuestion($question) {
$this->question = $question;
}
public function getSurveys() {
return $this->surveys;
}
public function setSurveys(ArrayCollection $surveys) {
$this->surveys = $surveys;
}
public function __toString() {
return __CLASS__ . ": [id: {$this->id}, name: {$this->name}]";
}
}
What is the mistake i am doing here, this is my code to get the surveys and questions:
$surveysInterface = $this->surveyService->getAllSurveys();
foreach($surveysInterface as $survey){
$surveysArray[] = array(
'id' => $survey->getId(),
'title' => $survey->getTitle(),
'description' => $survey->getDescription(),
'isActive' => $survey->getActive(),
'questions' => array(
'question' => $survey->getQuestions()->getQuestion()
)
);
}
'questions' => array(
'question' => $survey->getQuestions()->getQuestion()
)
This part look wrong since getQuestions() function return array of Questions entities. Suggest to change it to
'questions' => $survey->getQuestions()
I have a self referencing entity in Doctrine but I keep getting the following error when I try to persist them:
PHP Catchable fatal error: Object of class Category could not be converted to string in vendor/doctrine/dbal/lib/Doctrine/DBAL/Statement.php on line 165
Example:
$category1 = new Category();
$category1->setName("Foo");
$category1->setParent( NULL );
$category2 = new Category();
$category2->setName("Bar");
$category2->setParent( $category1 );
$manager->persist( $category1 );
$manager->persist( $category2 );
$manager->flush();
My entity looks like this:
/**
* #ORM\Table(name="categories")
* #ORM\Entity
*/
class Category {
/**
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Column(type="integer")
*/
protected $id;
/**
* #ORM\Column(type="string", length=64, unique=true)
*/
protected $name;
/**
* #ORM\Column(nullable=true)
* #ORM\ManyToOne(targetEntity="Category", inversedBy="children")
* #ORM\JoinColumn(name="parent_id", referencedColumnName="id")
*/
protected $parent;
/**
* #ORM\OneToMany(targetEntity="Category", mappedBy="parent")
*/
protected $children;
public function __construct()
{
$this->children = new ArrayCollection();
}
public function getId()
{
return $this->id;
}
public function getName()
{
return $this->name;
}
public function setName( $name )
{
$this->name = $name;
return $this;
}
public function getParent()
{
return $this->parent;
}
public function setParent( Category $parent = NULL )
{
$this->parent = $parent;
return $this;
}
public function getChildren()
{
return $this->children;
}
public function setChildren( ArrayCollection $children )
{
$this->children = $children;
return $this;
}
}
I have Googled and compared my code to other examples but I can't seem to spot the problem. I'm obviously overlooking something, but what?
Try to use
/**
* #ORM\ManyToOne(targetEntity="Category", inversedBy="children")
* #ORM\JoinColumn(name="parent_id", referencedColumnName="id", nullable=true)
*/
protected $parent;
But I also recommend you to set onDelete="SET NULL" on the parent column, like this:
/**
* #ORM\ManyToOne(targetEntity="Category", inversedBy="children")
* #ORM\JoinColumn(name="parent_id", referencedColumnName="id", onDelete="SET NULL")
*/
public $parent;
I know it's not part of the question, but you are probably going to need this in the near future. If you want the children column to give you the categories in a order that the user can choose, you may want to add a integer column named order and define children like this:
/**
* #ORM\OneToMany(targetEntity="Category", mappedBy="parent")
* #ORM\OrderBy({"order" = "ASC"})
*/
public $children;

What am I doing wrong?
I think you have a problem with your mappedBy and inversedBy attributes in the manyToMany annotations. They should match the other entities property name, grupos and permissoes. Try this:
/**
* #ORM\ManyToMany(targetEntity="User\Entity\Permissao", mappedBy="grupos", cascade={"remove"})
*/
protected $permissoes;
/**
* #ORM\ManyToMany(targetEntity="User\Entity\Grupo", inversedBy="permissoes", cascade={"persist", "remove"})
* #ORM\JoinTable(name="grupo_permissao",
* joinColumns={#ORM\JoinColumn(name="permissao_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="grupo_id", referencedColumnName="id")}
* )
*/
protected $grupos;
