EasyAdminBundle 3:collection field with entity

Question

I have two classes:

class Product {
     /**
     * @ORM\OneToMany(targetEntity=Keyword::class, mappedBy="product")
     */
    private $keywords;
}

class Keyword {
     /**
     * @ORM\Column(type="string", length=255)
     */
    private $description;

    /**
     * @ORM\ManyToOne(targetEntity=Product::class, inversedBy="keywords")
     */
    private $product;
}

In my CRUD controller of Product I defined:

public function configureFields(string $pageName): iterable
{
     yield CollectionField::new('keywords');
}

and it properly shows all the keywords but when I try to save it I get an error:

Expected argument of type "App\Entity\Keyword", "string" given at property path "keywords".

Is there a possibility to show such a connection as a Collection? It would be MUCH easier to manage keywords that way.

Answer 1

You need to use

yield AssociationField::new('keywords');

instead of

yield CollectionField::new('keywords');

Answer 2

You should create CRUD controller for Keyword entity and specify fields for records creation/editing.

After, you can use CollectionField in Product CRUD controller as below:

yield CollectionField::new('keywords')->useEntryCrudForm(KeywordsCrudController::class);
