我有一对多关系
书<----*>
书:
oneToMany:
bookImages:
targetEntity: BookImage
mappedBy: book
cascade: [persist,remove]
图书图片:
manyToOne:
book:
targetEntity: Book
inversedBy: bookImages
joinColumn:
name: book_id
referencedColumnName: id
所以我的表单有一个 collectionType 字段。
书籍类型:
$builder->add('bookImages', 'collection', array(
'type' => new BookImageType(),
'allow_add' => true,
// 'allow_delete' => true,
'by_reference' =>false
));
BookImageType:
$builder->add('imageName','text',array(
'constraints' => array(
new NotBlank(),
)
));
$builder->add('imageUrl','text',array(
'constraints' => array(
new NotBlank(),
)
));
Controller 通过 Ajax 调用保存数据:
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 BookImage 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，collectionType 字段值为 null 或为空？尽管其他字段具有完美的值(value)。谁能解释一下？还是我的结构有问题？提前致谢。

最佳答案
我一直在尝试寻找答案近 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submitData。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);
}
}
希望对其他人有帮助。
