Сделал так : /**

* @ORM\ManyToOne(targetEntity=News::class)
*/
private ?self $relatedNews;

/**
* @ORM\OneToMany(targetEntity=News::class, mappedBy="relatedNews")
*/
private ?Collection $related;

Видел, пробовал? https://stackoverflow.com/questions/45563694/doctrine-one-to-many-self-referencing-dont-work

Не видел, пробую

/** * @ORM\OneToMany(targetEntity=News::class, mappedBy="relatedNews") */ private $related; /** * @ORM\ManyToOne(targetEntity=News::class, inversedBy="related") * @ORM\JoinColumn(name="related_news_id", referencedColumnName="id", nullable=true) */ private $relatedNews;

бахни лимит на количество записей

Можна как то в аннотации?

Это работает при 100-200 новостей

Мне кажеться - все из-за запроса на все новости. Как мне ограничить их например к 10?
