doctrine

问题 I'm writing a feature which calls for the records of my joining table to carry extra metadata ( Joining-Table with Metadata ). I've attempted to implement this in accordance with this section of the Doctrine documentation. See below for example Entity definitions. The challenge now is that getGroups and setGroups do not yield/set Group entities (& the same is true from the Group instance perspective), but they yield GroupUser entities. This adds a substantial delay to process of managing this

问题 I want to set up a unique constraint on the fields "username" and "email" but it doesn't work : use Doctrine\ORM\Mapping as ORM; use Symfony\Component\Validator\Constraints as Assert; use FOS\UserBundle\Model\User as BaseUser; use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity; /** * @ORM\Table(name="acteurs") * @ORM\Entity(repositoryClass="UserBundle\Repository\ActeurRepository") * @ORM\InheritanceType("JOINED") * @UniqueEntity(fields="email", message="Cet email existe déjà.") *

问题 I set up a simple User->Comment association in Doctrine, simple OneToMany (One User can write many Comments). All works find, but i found a strange behavior of Doctrine. First some Code: User Entity /** * @ORM\Entity * @ORM\Table(name="users") */ class User extends EntityAbstract { /** * @var int * @ORM\Id * @ORM\Column(name="id", type="integer") * @ORM\GeneratedValue */ protected $_id; /** * @var \Doctrine\Common\Collections\Collection * @ORM\OneToMany(targetEntity="Comment", mappedBy=

问题 I have a ManyToMany relation (an offer can have many banners, and a banner can belong to many offers). I don't understand why this works: $banner->getOffers()->removeElement($this->offer); But this doesn't: $this->offer->getBanners()->removeElement($banner); These are my entities: Class Banner { /** * @ORM\ManyToMany(targetEntity="AppBundle\Entity\Offer", inversedBy="banners") */ private $offers; public function __construct() { $this->offers = new ArrayCollection(); } public function

问题 For example, i have playlist of 5000-10000 videos, what is the best way to select and show those videos in list. Pager is not an option, I need to have all of them becouse sorting and other functionalities? I thinking about solution to load list while scrolling the playlist, but this make me another problem, if i dont have all videos loaded, i can not properly save playlist. All suggestions/proposals are welcome... 回答1: use a dynamic pagination i.e, dont bring every thing to the frontend,

问题 Via composer i installed doctrine dbal and symfony2 config component "require":{ "symfony/dependency-injection": "2.4.*", "symfony/filesystem": "2.4.*", "symfony/config": "2.4.*", "doctrine/dbal": "2.3.4" } I autoload them via require_once __DIR__ . '/vendor/autoload.php' Then code goes like this use Symfony\Component\DependencyInjection\ContainerBuilder; $container = new ContainerBuilder(); $loader = new YamlFileLoader($container, new FileLocator(__DIR__ . '/app/config/')); $loader->load(

问题 I know you can soft delete in Doctrine (i.e. do not delete a record but rather add a "deleted" value). There's an extension for that. Now I wonder if there's a way to "soft update" a record. I mean not actually update the record but rather create a new record and make the old one invalid. In the same extension as soft-delete, there's a function loggable , but this one logs to a different table. I could create a controller that, instead of updating, soft-deletes (and thus invalidates) the old

问题 I have a question about knp paginator. I use Symfony 2.8. I made a table that has composite primary key, and corresponding list page using knp paginator. I'm receiving the exception when I try to show. "Single id is not allowed on composite primary key in entity" I tried to inspect source files of knp paginator and doctrine. So I found a workaround. 1)Set knp option "distinct" to false; 2)Set following hints to query. set "knp_paginator.count" to rows count of query result. set "knp_paginator

问题 I defined an Symfony2 entity class and I want to create the corresponding table in my database. This works fine thanks to the command 'php app/console doctrine:schema:update --force'. But the order of the columns isn't equal to the order in my class. Any way to get them in the same order? 来源： https://stackoverflow.com/questions/27283284/how-to-determine-order-of-colums-in-table
