Комментарии к публикации
Работа с доктриной. Многие ко многим: связываем посты с категориями

Хотел уточнить один момент.
Могу ли я из одной формы отправлять данные в две сущности? Если да, то каким образом?
То есть, если создаётся пост, сразу при создании указывать и теги, которые принадлежат посту.

Здравствуйте!

Помогите, пожалуйста.
При выполнении команды php bin/console doctrine:migrations:diff возникает ошибка
