One to One relationship in SonataAdmin

Question

i trying to make admin page for Product which has relationship 1:1 with image.

Product

/**
 * @ORM\Entity
 * @ORM\Table(name="products")
    class Product
    {

        /**
         * @ORM\Column(type="integer")
         * @ORM\GeneratedValue
         * @ORM\Id
         * @var int
         */
         private $id = 0;

        /**
         * @ORM\OneToOne(targetEntity="Image", mappedBy="product")
         */


               private $image;
  /**
     * @return Image
     */
    public function getImage(): ?Image
    {
        return $this->image;
    }

    /**
     * @param Image $image
     */
    public function setImage(Image $image)
    {
        $this->image = $image;
        return $this;
    }
    }

Image

/**
 * @ORM\Entity
 * @ORM\Table(name="images")
 */
class Image
{
    /**
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue
     * @ORM\Id
     * @var int
     */
    private $id = 0;

    /**
     * @ORM\OneToOne(targetEntity="Product", inversedBy="image")
     * @ORM\JoinColumn(name="product_id", referencedColumnName="id")
     */
    private $product;

  /**
     * @return mixed
     */
    public function getProduct()
    {
        return $this->product;
    }

    public function setProduct(Product $product)
    {
        $this->product = $product;
    }
}

ProductAdmin

class ProductAdmin extends AbstractAdmin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper->add('image', 'sonata_type_admin', array('label' => 'Okładka', 'by_reference' => false,));
}

ImageAdmin

class ImageAdmin extends AbstractAdmin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->add('file', 'file', array('label' => 'Okładka', 'required' => false))
            ->add('path', 'text', array('label' => 'Scieżka do pliku', 'required' => false));

Try to not initialize your $id

private $id = 0; // =====> this is a private $id;

You have several mistakes. Let's try to correct your code.

Just follow the tutorials and put right annotation for $id:

/**
 * @var integer $id
 *
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
 protected $id;

Hope, that this is just a typo with "?Image":

/**
 * @return Image
 */
 public function getImage() : Image
 {
      return $this->image;
 }

And finally.

 /**
  * Class ProductAdmin
  */
class ProductAdmin extends AbstractAdmin
{
     protected function configureFormFields(FormMapper $formMapper)
     {
         $formMapper
             ->add('image', 'sonata_type_model_list', [
                      'btn_add'       => true,      //Or you can specify a custom label
                      'btn_list'      => 'list button!',     //which will be translated
                      'btn_delete'    => false,             //or hide the button.
                      'btn_catalogue' => 'messages', //Custom translation domain for buttons
                      'label'         => 'My image',
                  ], [
                      'placeholder'   => $this->trans('messages.no_images_message'),
                      'edit'          => 'standard',
                      'inline'        => 'standard',
                      'sortable'      => 'id',
                  ])
          ;
     }
}
