Crossing multiple entities in EasyAdmin 3 - php

Question

I've got a 3 entities and I would like to get property from entity 1 to entity 3. Let me explain with my classes :
class City
{
#[ORM\Column(type: 'string', length: 255)]
#[Assert\NotBlank]
#[Assert\Length(min: 1)]
private string $name;
#[ORM\Column(type: 'string', length: 20)]
#[Assert\NotBlank]
private string $code;
#[ORM\OneToOne(targetEntity: CityHomePage::class, cascade: ['persist', 'remove'])]
private CityHomePage $homePage;
public function getHomePage(): CityHomePage
{
return $this->homePage;
}
public function setHomePage(CityHomePage $homePage): self
{
$this->homePage = $homePage;
return $this;
}
}
class CityHomePage
{
#[ORM\OneToOne(targetEntity: City::class, cascade: ['persist', 'remove'])]
#[ORM\JoinColumn(nullable: false)]
private City $city;
#[ORM\ManyToOne(targetEntity: Page::class, inversedBy: 'cityHomePages')]
#[ORM\JoinColumn(nullable: false)]
private Page $page;
#[ORM\OneToOne(targetEntity: Image::class, cascade: ['persist', 'remove'])]
private Image $image;
public function getCity(): ?City
{
return $this->city;
}
public function setCity(City $city): self
{
$this->city = $city;
return $this;
}
public function getPage(): ?Page
{
return $this->page;
}
public function setPage(?Page $page): self
{
$this->page = $page;
return $this;
}
public function getImage(): Image
{
return $this->image;
}
public function setImage(Image $image): self
{
$this->image = $image;
return $this;
}
}
class Page
{
#[ORM\Column(type: 'string', length: 100)]
#[Assert\Length(min: 1)]
private string $title;
/** #var Collection<int, CityHomePage> */
#[ORM\OneToMany(mappedBy: 'page', targetEntity: CityHomePage::class, cascade: ['persist', 'remove'], orphanRemoval: true)]
private Collection $cityHomePages;
public function __construct()
{
parent::__construct();
$this->cityHomePages = new ArrayCollection();
}
public function getTitle(): ?string
{
return $this->title;
}
public function setTitle(string $title): self
{
$this->title = $title;
return $this;
}
/**
* #return Collection<int, CityHomePage>
*/
public function getCityHomePages(): Collection
{
return $this->cityHomePages;
}
public function addCityHomePage(CityHomePage $cityHomePage): self
{
if (!$this->cityHomePage->contains($cityHomePage)) {
$this->cityHomePage[] = $cityHomePage;
$cityHomePage->setPage($this);
}
return $this;
}
public function removeCityHomePage(CityHomePage $cityHomePage): self
{
if ($this->cityHomePage->removeElement($cityHomePage) && $cityHomePage->getPage() === $this) {
$cityHomePage->setPage(null);
}
return $this;
}
}
I created a CityCrudController and in my configurationField I add :
public function configureFields(string $pageName): iterable
{
return [
TextField::new('name',$this->translator->trans('EA.name'))->onlyOnIndex(),
TextField::new('code')->onlyOnIndex(),
AssociationField::new('homePage', $this->translator->trans('EA.image'))->onlyWhenUpdating(),
];
}
This is work but now I need to access from my CityCrudController the property 'title' from the Entity Page.
Is it a way to cross multiple entity to get what I need ?

Answer 1

Ok I found it => 'city.page.title'
