Я получаю следующую ошибку:

Ожидаемое значение типа «SourcingBundle Entity RequestForEstimate» для поля ассоциации «SourcingBundle Entity RequestForEstimateDetail # $ detail» вместо этого получило «Doctrine Common Collections ArrayCollection».

Я пытаюсь создать структуру, в которой есть объект RequestForEstimate, который может иметь несколько узлов RequestForEstimateDetails. Просто каждая строка в RequestForEstimateDetails будет содержать запрос на другой продукт и его детали, когда requestforest оценивает только общую информацию. Я новичок в Symfony, и мне трудно в тот момент, когда я хочу сохранить родительский элемент вместе с дочерними элементами в БД. Я следил за этим руководством по Symfony: как внедрить коллекцию форм

Вот мой код:

В RequestForEstimateDetail методе getter / setter поля detail предназначены для управления самой коллекцией (методы добавления / удаления предназначены для одного элемента коллекции), поэтому измените метод getter / setter для обработки ArrayCollection объекта.

В качестве примера:

RequestForEstimateDetail

 /**
 * Set detail
 *
 * @param DoctrineCommonCollectionsArrayCollection an array of $detail
 *
 * @return RequestForEstimateDetail
 */
public function setDetail(DoctrineCommonCollectionsArrayCollection $detail = null)
{
    $this->detail = $detail;

    return $this;
}

/**
 * Get detail
 *
 * @return DoctrineCommonCollectionsArrayCollection
 */
public function getDetail()
{
    return $this->detail;
}
  

Надеюсь, это поможет

Что ж, существующий метод addDetail в сущности RequestForEstimate сделал свое дело:

 public function addDetail(SourcingBundleEntityRequestForEstimateDetail $detail)
{
    $this->details->add($detail);
    $detail->setDetail($this);
    return $this;
}
