ODM

Document

use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;

#[ODM\Document(collection: 'Company')]
class Company
{
    #[ODM\Id(type: 'string', strategy: 'auto')]
    private ?string $id = null;
}

EmbeddedDocument

NOTE : don't add primary key to an embedded document

EmbedOne

use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;

#[ODM\EmbeddedDocument]
class Registration
{
    // without id
}

#[ODM\Document(collection: 'Company')]
class Company
{
    #[ODM\Id(type: 'string', strategy: 'auto')]
    private ?string $id = null;

    #[ODM\EmbedOne(targetDocument: Registration::class)]
    private Registration $registration;
}

EmbedMany

use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;

#[ODM\EmbeddedDocument]
class Address
{
}

#[ODM\Document(collection: 'Company')]
class Company
{
    #[ODM\Id(type: 'string', strategy: 'auto')]
    private ?string $id = null;

    #[ODM\EmbedMany(targetDocument: Address::class)]
    private Collection $addresses;
    
    public function __construct()
    {
        $this->addresses = new ArrayCollection();
    }
}

ReferenceDocument

ReferenceOne

use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;

#[ODM\Document(collection: 'Product')]
class Product
{
    #[ODM\Id(type: 'string', strategy: 'auto')]
    private ?string $id = null;

    #[ODM\ReferenceOne(targetDocument: Store::class, cascade: 'persist')]
    private Store $store;
}

#[ODM\Document(collection: 'Store')]
class Store
{
    #[ODM\Id(type: 'string', strategy: 'auto')]
    private ?string $id = null;
}

ReferenceMany

use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;

#[ODM\Document(collection: 'Store')]
class Store
{
    #[ODM\Id(type: 'string', strategy: 'auto')]
    private ?string $id = null;
    
    #[ODM\ReferenceMany(targetDocument: Product::class, mappedBy: 'store')]
    private Collection $products;

    public function __construct()
    {
        $this->products = new ArrayCollection();
    }
}

#[ODM\Document(collection: 'Product')]
class Product
{
    #[ODM\Id(type: 'string', strategy: 'auto')]
    private ?string $id = null;

    // inversedBy is optional, don't add it if you don't need the bi-directional reference
    #[ODM\ReferenceOne(targetDocument: Store::class, cascade: 'persist', inversedBy: 'products')]
    private Store $store;
}
