Symfony 3形成pre-populate集合字段类型

Question

是否可以使用某些默认项目填充集合 假设您有价格集合，但每个价格可以是不同类型。我想要的是该集合总是有一些预定义的（生成某种方式）项目？

    $form = $this->createForm(AdminStampForm::class, $stamp);

    $form->handleRequest($request);
    if ($form->isSubmitted() && $form->isValid()) {

        $stamp = $form->getData();

        $user = $this->getUser();

        $stamp->setCountry($user->getAdminConfig()->getCountry());

        $em = $this->getDoctrine()->getManager();
        $em->persist($stamp);
        $em->flush();

        $this->addFlash('success', 'Successfully added a new stamp!');

    return [
        'form' => $form->createView(),
    ];
}

所以我试图填充Stamp实体本身。但我真正需要的是有4个单独的字段集价格（每个字段设置为价格类型）。并且（和）有一些预定义的 $ priceType-＆gt; isPredefined（）价格。我不确定你是否理解我想说的话。所以我会回答所有即将到来的问题。
