Doctrine Sluggable — столбец «слаг» не может быть нулевым

Я использую Doctrine с DoctrineExtensions через StofDoctrineExtensionsBundle для автоматического создания слагов, используя поведение «Doctrine Extensions Sluggable».

Слушатель, кажется, зарегистрирован правильно. Поле Entity также помечено как suggable.

При попытке сохранить мою сущность через форму Symfony генерация слагов не происходит. Возникает исключение базы данных.

Исключение:

An exception occurred while executing 'INSERT INTO event (startDate, endDate, title, slug, description, image, followers, city, place) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)' with params ["2017-06-24 20:00:00", "2017-06-26 12:00:00", "Test event name for slug generation", null, "Test", null, null, "Somewhere", "Somewhere else"]:

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'slug' cannot be null

Вам не нужно включать весь код, чтобы понять, что сообщение об ошибке, которое вы получаете: Column 'slug' cannot be null — это именно то, что оно говорит: схема БД не допускает null значений для этого столбца!   -  person Koby Douek    schedule 12.06.2017

@KobyDouek слаг должен генерироваться автоматически с помощью расширения Doctrine ORM Sluggable. Вот так. Это поле должно быть заполнено слушателем Sluggable   -  person Kacper    schedule 12.06.2017

@Kacper единственная разница, которую я вижу, заключается в объявлении вашего пространства имен xml. Вы ссылаетесь на URL версии 3.x, используя версию 2.x.

Когда я реализовал StofDoctrineExtensionsBundle, я впервые выполнил функцию, которая установила все значения slug в null. (Когда для slug установлено значение null, прослушиватель вызывается, значение slug заполняется.

Надеюсь это поможет.

Вызов $entity->setSlug(null) вручную не помогает, к сожалению - person Kacper; 20.06.2017

Как говорит вам исключение:

'slug' cannot be null

Вам нужно изменить определение свойства в Event.orm.xml и сделать слаг обнуляемым, поскольку по умолчанию он имеет значение nullable false.

Итак, вам нужно изменить свое определение следующим образом:

        <field name="slug" type="string" column="slug" length="255" unique="true" nullable="false">
            <gedmo:slug unique="true" updatable="true" fields="title" separator="-" />
        </field>

Это разрешит ваше исключение. Но реальная проблема заключается в уникальном ограничении свойства slug: во второй раз, когда вы вставите событие со значением «null», оно активирует уникальное ограничение, потому что уже есть строка с нулевым slug. Таким образом, вам нужно предоставить слаг или удалить уникальное ограничение.

Что ж, расширение Doctrine Sluggable должно предоставить «слаг». Я попытался установить nullable на true и сбросить ограничение unique. Дело в том, что слаг не генерируется DoctrineExtensions. - person Kacper; 12.06.2017
