doctrine OneToMany - не работает каскад

Question

У меня есть проблема, когда doctrine не сохранит ArrayCollection при сохранении (). У меня есть Post, и я добавляю Tag к нему из формы отправки, а затем пытаюсь сохранить его (основы c). На persist () Post сохраняется, а отношения тегов - нет.

Сброс Post перед сохранением () показывает, что теги есть.

Чего мне не хватает?

Я тупой. Я добавлял теги в свойство tags объекта, а не в свойство tag.
