Symfony 3. Problems with join and the VichUploaderBundle - sql

Question

I load several pictures with the Vichuploaderbundle and the EntryImg Entity.
That is successful!
I have also an Entity named Entries.
Each Entry should be linked with one or more Images
I want to join both Entities in the Repository.
What is the error?
Here is my Entries Entity
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
//use Vich\UploaderBundle\Mapping\Annotation as Vich;
/**
* #ORM\Entity(repositoryClass="AppBundle\Repository\EntriesRepository")
* #ORM\Table(name="entries")
*/
class Entries
{
/**
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Column(type="integer")
* #ORM\OneToMany(targetEntity="AppBundle\Entity\EntryImg", mappedBy="entries")
*/
private $id;
/**
* #ORM\Column(type="string")
*/
private $name;
/**
* #ORM\Column(type="text")
*/
private $description;
/**
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\User")
* #ORM\JoinColumn()
*/
private $user;
public function getId()
{
return $this->id;
}
public function getName()
{
return $this->name;
}
public function setName($name)
{
$this->name = $name;
}
public function getDescription()
{
return $this->description();
}
public function setDescription($description)
{
$this->description = $description;
return $this;
}
public function getUser()
{
return $this->user;
}
public function setUser(User $user)
{
$this->user = $user;
}
}
My Image Entity
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\HttpFoundation\File\File;
//use Symfony\Component\HttpFoundation\File\UploadedFile;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
/**
* #ORM\Entity
* #ORM\Table(name="`entry_img`")
* #Vich\Uploadable
*/
class EntryImg
{
/**
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Column(type="integer")
*/
protected $id;
/**
* #ORM\Column(type="string", length=255)
* #var string
*/
private $image;
/**
* #Assert\File(maxSize="2000k",mimeTypes={"image/png", "image/jpeg", "image/pjpeg"})
* #Vich\UploadableField(mapping="entry_images", fileNameProperty="image")
* #var File
*/
private $imageFile;
/**
* #ORM\Column(type="datetime")
* #var \DateTime
*/
private $updatedAt;
/**
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\Entries")
* #ORM\JoinColumn(name="entries_id",referencedColumnName="id",nullable=true)
*/
private $entry;
public function setImageFile(File $image = null)
{
$this->imageFile = $image;
// VERY IMPORTANT:
// It is required that at least one field changes if you are using Doctrine,
// otherwise the event listeners won't be called and the file is lost
if ($image) {
// if 'updatedAt' is not defined in your entity, use another property
$this->updatedAt = new \DateTime('now');
}
}
public function getImageFile()
{
return $this->imageFile;
}
public function setImage($image)
{
$this->image = $image;
}
public function getImage()
{
return $this->image;
}
public function getId()
{
return $this->id;
}
public function getEntry(){
return $this->entry();
}
public function setEntry(Entries $entry){
$this->entry = $entry;
}
}
and my repository
<?php
namespace AppBundle\Repository;
use AppBundle\Entity\Entries;
use AppBundle\Entity\EntryImg;
use Doctrine\ORM\EntityRepository;
class EntriesRepository extends EntityRepository
{
public function findAllEntries($e_ids)
{
$query = $this->createQueryBuilder('e')
->leftJoin('e.id','entry_img');
$i = 0;
foreach($e_ids as $e_id){
if($i==0){
//var_dump($e_id);
$query->where('e.id = :entries_'.$i)
->setParameter('entries_'.$i,$e_id['entry']);
}else if($i>0){
$query->orWhere('e.id = :entries_'.$i)
->setParameter('entries_'.$i,$e_id['entry']);
}
$i++;
}
$result = $query->getQuery()->execute();
return $result;
}

Answer 1

In your class Entries, you have this line:
#ORM\OneToMany(targetEntity="AppBundle\Entity\EntryImg", mappedBy="entries")
But in your EntryImg class, there isn't any $entries property.
Also, if 1 Entries can have many EntryImg, you need to use arraycollection.
I think you should rewrite your Entries class like this:
use Doctrine\Common\Collections\ArrayCollection; //don't forget this line for the constructor
class Entries
{
/**
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Column(type="integer")
//look here I remove the relation and put it on $entriesImg property
*/
private $id;
/**
* #ORM\Column(type="array")
* #ORM\OneToMany(targetEntity="AppBundle\Entity\EntryImg", mappedBy="entry") //look here I changed "entries" by "entry" which is the actual property in your EntryImg class. (you did not have any $entries property)
*/
private $entriesImg;
.. the rest of your properties
public function __construct()
{
$this->entriesImg= new ArrayCollection();
}
public function addEntryImg(\AppBundle\Entity\EntryImg $entryImg)
{
$this->entriesImg[] = $entryImg;
return $this;
}
public function removeEntryImg(\AppBundle\Entity\EntryImg $entryImg)
{
$this->entriesImg->removeElement($entryImg);
}
// also don't forget to implement classic getters and setters for the $entriesImg property
Don't forget to implement a toString method for both your entities, you will need it for Crud operation.
Then, later in your repository, you forgot to use the ->addSelect(); method like this
class EntriesRepository extends EntityRepository
{
public function findAllEntries()
{
$query = $this->createQueryBuilder('e')
->leftJoin('e.entriesImg','i');
->addSelect('i')
// whatever from your logic ....
