我有一对多关系
图书<----* 图书图片
书：
oneToMany:
bookImages:
targetEntity: BookImage
mappedBy: book
cascade: [persist,remove]
书籍图片：
manyToOne:
book:
targetEntity: Book
inversedBy: bookImages
joinColumn:
name: book_id
referencedColumnName: id
所以我的表单有一个集合类型字段。
书籍类型：
$builder->add('bookImages', 'collection', array(
'type' => new BookImageType(),
'allow_add' => true,
// 'allow_delete' => true,
'by_reference' =>false
));
书籍图像类型：
$builder->add('imageName','text',array(
'constraints' => array(
new NotBlank(),
)
));
$builder->add('imageUrl','text',array(
'constraints' => array(
new NotBlank(),
)
));
通过 Ajax 调用保存数据的控制器：
public function addNewSellBookAction(Request $request)
{
$serializer = $this->container->get('jms_serializer');
$userId = $this->get('security.token_storage')->getToken()->getUser()->getId();
$em = $this->getDoctrine()->getManager();
$content = $request->get('book');
$bookData = json_decode($content, true);
$book = new Book();
$bookImage1 = new BookImage();
$bookImage1->setImageName("Amazon Book Image");
$bookImage1->setImageUrl("http://url1.com");
$book->addBookImage($bookImage1);
$bookImage2 = new BookImage();
$bookImage2->setImageName("Amazon Book Image");
$bookImage2->setImageUrl("http://url1.com");
$book->addBookImage($bookImage2);
$bookData['bookSeller']=$userId;
$bookForm = $this->createForm(new BookType(), $book);
var_dump($bookForm->getData()->getBookImages()); //Image Data Before Submit
$bookForm->submit($bookData);
var_dump($bookForm->getData()->getBookImages()); //Image Data After Submit
if($bookForm->isValid()){
$em->persist($book);
$em->flush();
return $this->createJsonResponse('success',array('successTitle'=>"Book Successfully added to sell List"));
}else{
$error= $serializer->serialize($bookForm,'json');
return new Response($error,200);
}
}
现在提交前后的书籍图像数据是：
object(Doctrine'Common'Collections'ArrayCollection)[580]
private 'elements' =>
array (size=2)
0 =>
object(AppBundle'Entity'BookImage)[581]
protected 'id' => null
private 'imageName' => string 'Amazon Book Image' (length=17)
private 'imageUrl' => string 'http://url1.com' (length=15)
private 'titleImage' => null
private 'book' =>
object(AppBundle'Entity'Book)[578]
...
1 =>
object(AppBundle'Entity'BookImage)[582]
protected 'id' => null
private 'imageName' => string 'Amazon Book Image' (length=17)
private 'imageUrl' => string 'http://url1.com' (length=15)
private 'titleImage' => null
private 'book' =>
object(AppBundle'Entity'Book)[578]
...
object(Doctrine'Common'Collections'ArrayCollection)[580]
private 'elements' =>
array (size=2)
0 =>
object(AppBundle'Entity'BookImage)[581]
protected 'id' => null
private 'imageName' => null
private 'imageUrl' => null
private 'titleImage' => boolean false
private 'book' =>
object(AppBundle'Entity'Book)[578]
...
1 =>
object(AppBundle'Entity'BookImage)[582]
protected 'id' => null
private 'imageName' => null
private 'imageUrl' => null
private 'titleImage' => boolean false
private 'book' =>
object(AppBundle'Entity'Book)[578]
为什么提交数据后集合类型字段值为空或空？尽管其他字段具有完美的价值。谁能解释一下？还是我对结构有任何问题？提前谢谢。

我已经尝试了将近 7 天，终于想出了一个解决方案。但不知道这是否是一种不好的做法。
只需将数据作为数组放入提交数据中即可。提交后，该值将通过表单添加到该特定实体。
public function addNewSellBookAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$serializer = $this->container->get('jms_serializer');
$userId = $this->get('security.token_storage')->getToken()->getUser()->getId();
$content = $request->get('book');
$bookData = json_decode($content, true);
$bookData['bookImages']=array();
array_push($bookData['bookImages'],array(
'imageName'=>"Amazon Book Image",
'imageUrl'=>"http://url1.com"
));
array_push($bookData['bookImages'],array(
'imageName'=>"Amazon Book Image",
'imageUrl'=>"http://url1.com"
));
$bookData['bookSeller']=$userId;
$book = new Book();
$bookForm = $this->createForm(new BookType(),$book);
var_dump($bookForm->getData()->getBookImages());
$bookForm->submit($bookData);
var_dump($book->getBookImages());
if($bookForm->isValid()){
$em->persist($book);
$em->flush();
return $this->createJsonResponse('success',array('successTitle'=>"Book Successfully added to sell List"));
}else{
$error= $serializer->serialize($bookForm,'json');
return new Response($error,200);
}
}
希望它能帮助其他人。
赏金仍然开放，如果有人提供最佳实践的答案
我不确定。根据symfony的文档
检查任务控制器行号 20 和 23
$task->getTags()->add($tag2);
标签集合可以通过$task->getTags（）自然访问，并且可以持久保存到数据库中或根据需要使用。
我认为你在这里错过了一些东西
$book->addBookImage（$bookImage 1）;
试试这个
$book->getBookImages()->add($bookImage1);
如果您不需要修改带有请求数据的图像，请在提交表单后添加新图像。
$bookForm->submit($bookData);
// ...
$book->addBookImage($bookImage1);
