Symfony3对AppBundle\Entity\的查询缺少标识符ID [英] Symfony3 The identifier id is missing for a query of AppBundle\Entity\
问题描述
我是symfony的新手,我正尝试使用以下方法将对象从列表传递到新页面:
< a href = {{path('fooUpdate',{'id':item.id})}}>> Update< / a>
Foo对象的列表({%用于列表%}中的项)
很好,这些对象已从数据库中完全加载,但是由于以下原因该链接不起作用此教义错误:
AppBundle\Entity\Foo
的查询缺少标识符ID p>
这里是Foo类:
namespace AppBundle\Entity;
使用Doctrine\ORM\Mapping作为ORM;
/ **
* @ ORM\实体
* @ ORM\Table(name = foo)
* /
类Foo {
/ **
* @ ORM\Id
* @ ORM\Column(type = integer)
* @ ORM\GeneratedValue
* /
私人$ id;
/ **
* @ ORM\Column(type = string)
* /
private $ description;
//获取和设置
这是控制器方法:
/ **
* @Route( / foo / fooUpdate /,name = fooUpdate)
* /
公共功能updateAction($ id,Request $ request){
$ foo = $ this-> getDoctrine()-> getRepository('AppBundle:Foo')-> find ($ id);
return $ this-> render(’/ foo / fooUpdate.html.twig',array(
‘foo’=> $ foo
));
}
链接本身看起来正常,因为错误的URL是:
http://127.0.0.1:8000/foo/fooUpdate/?id=1
所以我想念什么?
还有,有什么办法
您在路由中缺少该ID:
@Route( / foo / fooUpdate / {id},name = fooUpdate)
I am new to symfony and I am trying to pass a object from a list to a new page using:
<a href="{{ path('fooUpdate', { 'id': item.id }) }}">Update</a>
The list ({% for item in list %})
of Foo objects is fine, the objects are fully loaded from the database, but the link does not work because of this Doctrine error:
The identifier id is missing for a query of AppBundle\Entity\Foo
Here is the Foo class:
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity
* @ORM\Table(name="foo")
*/
class Foo {
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue
*/
private $id;
/**
* @ORM\Column(type="string")
*/
private $description;
//getters and setters
And here is the controller method:
/**
* @Route("/foo/fooUpdate/", name="fooUpdate")
*/
public function updateAction($id, Request $request) {
$foo = $this->getDoctrine()->getRepository('AppBundle:Foo')->find($id);
return $this->render('/foo/fooUpdate.html.twig', array(
'foo' => $foo
));
}
The link itself looks like it is working, because the URL of the error is:
http://127.0.0.1:8000/foo/fooUpdate/?id=1
So what am I missing?
Also, is there any way of doing this using POST, so the id will not appear in the URL?
You are missing the id in the route:
@Route("/foo/fooUpdate/{id}", name="fooUpdate")
