Symfony2: отношения один ко многим

Испытывайте некоторые серьезные проблемы с получением отношения OneToMany к работе. Ошибка возникает при попытке добавить "Дети" к "Красавицам" в "Администраторе сонаты".

С помощью:

Помощь по форуму Symfony2

Пробовал следовать руководству по адресу: http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/association-mapping.html#one-to-many-bireirectional

а также

http://sonata-project.org/bundles/doctrine-orm-admin/2-2/doc/reference/form_field_definition.html

Ошибка:

"КРИТИЧЕСКАЯ - Неотредактированная доктрина исключения PHP ORM\ORMInvalidArgumentException:" Новый объект был найден через связь "Beautify\BeautiesBundle\Entity\Beauty # children", которая не была настроена на каскадное сохранение операций для объекта: Beautify\BeautiesBundle\Entity\Children @000000000eff91d5000000017f8ca53b. Чтобы решить эту проблему: либо явно вызовите EntityManager # persist() на этом неизвестном объекте, либо сконфигурируйте каскад, сохраняйте эту ассоциацию в сопоставлении, например, @ManyToOne (.., cascade = {"persist"}). Если вы не можете выяснить, какой объект вызывает проблему, выполните "Beautify\BeautiesBundle\Entity\Children #__ toString()", чтобы получить ключ.
