如何从Doctrine Fixture参考获取实体？

本文介绍了如何从Doctrine Fixture参考获取实体？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 在数据夹具中，我添加了一些实体引用，例如： // GroupEntity_Fixtures.php文件 $ this-> addReference（'GROUP_USER'，$ groupUser）; $ this-> addReference（'GROUP_ADMIN'，$ groupAdmin）; 其中$ groupAdmin和$ groupUser都是Group（）实体。在我的第二个夹具文件中，我想通过以下方式将这些实体添加到我的用户实体： //UserEntity_Fixtures.php文件 $ userActive-> addGroup（$ this-> getReference（'GROUP_USER'））; $ userActive是一个与组实体有多对多关系的用户实体。不幸的是，我只是传递一个实体的代理，而不是实体本身，它呈现以下错误： Symfony\Component\Debug\Exception\ContextErrorException] 可追踪致命错误：参数1传递给Blogger\BlogBu​​ndle\Entity\User：：addGroup（）必须是Blogger \BlogBu​​ndle\Entity\groups，instan ce of Proxies\__CG__\\BBger_\\BlogBu​​ndle\Entity\Group给出，在/ home / na / Practice / src中调用/ Blogger / BlogBu​​ndle / DataFixtures / ORM / CreateUserController_S ignUpForm_UserEntity_Fixtures.php在第27行并定义在/ home / na / Practi ce / src / Blogger / BlogBu​​ndle / Entity / User.php line 305 如何将代理引用转换为预期的实体？ 组装夹具代码： // DataFixtures / ORM / GroupEntity_Fixtrues.php 命名空间Blogger\BlogBu​​ndle\DataFixtures\ORM; 使用Doctrine\Common\DataFixtures\OrderedFixtureInterface; 使用Doctrine\Common\DataFixtures\AbstractFixture; 使用Doctrine\Common\Persistence\ObjectManager; 使用Blogger\BlogBu​​ndle\Entity\User; 使用Blogger\BlogBu​​ndle\Entity\Group; class GroupEntity_Fixtures extends AbstractFixture implements OrderedFixtureInterface { / ** * {@inheritDoc} * / public function load（ObjectManager $ manager { $ groupUser = new Group（）; $ groupUser-> setName（'GROUP_USER'）; $ groupUser-> setRole（'ROLE_USER'）; $ manager-> persist（$ groupUser）; $ groupAdmin = new Group（）; $ groupAdmin-> setName（'GROUP_ADMIN'）; $ groupAdmin-> setRole（'ROLE_USER，ROLE_ADMIN'）; $ manager-> persist（$ groupAdmin）; $ manager-> flush（）; $ this-> addReference（'GROUP_USER'，$ groupUser）; $ this-> addReference（'GROUP_ADMIN'，$ groupAdmin）; } public function getOrder（） { return 1; } } 用户夹具代码 <？php // DataFixtures / ORM / CreateUserController_SignUpForm_UserEntity_Fixtrues.php 命名空间Blogger\BlogBu​​ndle\DataFixtures \ORM; 使用Doctrine\Common\DataFixtures\OrderedFixtureInterface; 使用Doctrine\Common\DataFixtures\AbstractFixture; 使用Doctrine\Common\Persistence\ObjectManager; 使用Blogger\BlogBu​​ndle\Entity\User; 使用Blogger\BlogBu​​ndle\Entity\Group; class CreateUserController_SignUpForm_UserEntity_Fixtures extends AbstractFixture implements OrderedFixtureInterface { / ** * {@inheritDoc} * / public function load（ObjectManager $ manager { $ groupUser2 = new Group（）; $ groupUser2-> setName（'GROUP_USER'）; $ groupUser2> setRole（'ROLE_USER'）; $ manager-> persist（$ groupUser2）; //这个人代表一个活跃的（电子邮件验证的）用户。 $ userActive = new User（）; $ userActive-> setPassword（passwordActive）; $ userActive-> setEmail（[email protected]）; $ userActive-> setUserName（testActive）; $ userActive-> setPassword（crypt（$ userActive-> getPassword（），$ userActive-> getSalt（）））; $ userActive-> setEmailToken（md5（uniqid（rand（），true）））; $ userActive-> addGroup（$ groupUser2）; // $ userActive-> getGroups（） - > add（$ groupRepository-> getGroupByName（BASIC_USER））; //此人表示未激活（电子邮件未验证）用户。 $ userUnactive = new User（）; $ userUnactive-> setPassword（passwordUnactive）; $ userUnactive-> setEmail（[email protected]）; $ userUnactive-> setUserName（testUnactive）; $ userUnactive-> setPassword（crypt（$ userUnactive-> getPassword（），$ userUnactive-> getSalt（）））; $ userUnactive-> setEmailToken（md5（uniqid（rand（），true）））; //将对象保存到数据库 $ manager-> persist（$ userActive）; $ manager-> persist（$ userUnactive）; $ manager-> flush（）; } public function getOrder（） { return 2; } } 组实体代码： / ** * @ ORM\ManyToMany（targetEntity =User，inversedBy =groups） * private $ users; 用户实体代码： / ** * @ ORM\ManyToMany（targetEntity =Group，mappedBy =users） * / protected $ groups; 添加组Methos： / ** *添加组 * * @param \Blogger\BlogBu​​ndle\Entity\groups $ groups * @return用户 * / public function addGroup（\Blogger\BlogBu​​ndle\Entity\groups $ groups） { $ this-> groups [] = $ groups ; return $ this; } 解决方案 addGroup方法错误类型提示： 应该是： / ** *添加组 * * @param \Blogger\BlogBu​​ndle\Entity\Group $ groups * @return用户 * / public function addGroup（\Blogger\BlogBu​​ndle\Entity\Group $ groups） { $ this-> groups [] = $ groups; return $ this; } 通知\Blogger\BlogBu​​ndle\Entity\Group的\Blogger\BlogBu​​ndle\Entity\groups I have added data fixtures in my project that relies on referencing entity objects from each other.In data fixture one, I have added entity references such as: // GroupEntity_Fixtures.php file $this->addReference('GROUP_USER', $groupUser); $this->addReference('GROUP_ADMIN', $groupAdmin);Where $groupAdmin and $groupUser are both Group() entities. In my second fixtures file I want to add those entities to my User entity via: //UserEntity_Fixtures.php file $userActive->addGroup($this->getReference('GROUP_USER'));$userActive is a User entity with a Many to Many relationship to Group Entity. Unfortunately it seems that I am only passing in a proxy of the entity and not the entity itself which renders the following error: [Symfony\Component\Debug\Exception\ContextErrorException] Catchable Fatal Error: Argument 1 passed to Blogger\BlogBundle\Entity\User: :addGroup() must be an instance of Blogger\BlogBundle\Entity\groups, instan ce of Proxies\__CG__\Blogger\BlogBundle\Entity\Group given, called in /home /na/Practice/src/Blogger/BlogBundle/DataFixtures/ORM/CreateUserController_S ignUpForm_UserEntity_Fixtures.php on line 27 and defined in /home/na/Practi ce/src/Blogger/BlogBundle/Entity/User.php line 305How do I convert the reference from a proxy to the entity it expects?Code for Group Fixture:<?php// DataFixtures/ORM/GroupEntity_Fixtrues.phpnamespace Blogger\BlogBundle\DataFixtures\ORM;use Doctrine\Common\DataFixtures\OrderedFixtureInterface;use Doctrine\Common\DataFixtures\AbstractFixture;use Doctrine\Common\Persistence\ObjectManager;use Blogger\BlogBundle\Entity\User;use Blogger\BlogBundle\Entity\Group;class GroupEntity_Fixtures extends AbstractFixture implements OrderedFixtureInterface{ /** * {@inheritDoc} */ public function load(ObjectManager $manager) { $groupUser = new Group(); $groupUser->setName('GROUP_USER'); $groupUser->setRole('ROLE_USER'); $manager->persist($groupUser); $groupAdmin = new Group(); $groupAdmin->setName('GROUP_ADMIN'); $groupAdmin->setRole('ROLE_USER,ROLE_ADMIN'); $manager->persist($groupAdmin); $manager->flush(); $this->addReference('GROUP_USER', $groupUser); $this->addReference('GROUP_ADMIN', $groupAdmin); } public function getOrder() { return 1; }}Code for User Fixture<?php// DataFixtures/ORM/CreateUserController_SignUpForm_UserEntity_Fixtrues.phpnamespace Blogger\BlogBundle\DataFixtures\ORM;use Doctrine\Common\DataFixtures\OrderedFixtureInterface;use Doctrine\Common\DataFixtures\AbstractFixture;use Doctrine\Common\Persistence\ObjectManager;use Blogger\BlogBundle\Entity\User;use Blogger\BlogBundle\Entity\Group;class CreateUserController_SignUpForm_UserEntity_Fixtures extends AbstractFixture implements OrderedFixtureInterface{ /** * {@inheritDoc} */ public function load(ObjectManager $manager) { $groupUser2 = new Group(); $groupUser2->setName('GROUP_USER'); $groupUser2->setRole('ROLE_USER'); $manager->persist($groupUser2); // This person represents an active (email verified) user. $userActive = new User(); $userActive->setPassword("passwordActive"); $userActive->setEmail("[email protected]"); $userActive->setUserName("testActive"); $userActive->setPassword(crypt($userActive->getPassword(),$userActive->getSalt())); $userActive->setEmailToken(md5(uniqid(rand(), true))); $userActive->addGroup($groupUser2); //$userActive->getGroups()->add($groupRepository->getGroupByName("BASIC_USER")); // This person represents an unactive (email not verified) user. $userUnactive = new User(); $userUnactive->setPassword("passwordUnactive"); $userUnactive->setEmail("[email protected]"); $userUnactive->setUserName("testUnactive"); $userUnactive->setPassword(crypt($userUnactive->getPassword(),$userUnactive->getSalt())); $userUnactive->setEmailToken(md5(uniqid(rand(), true))); // Persist objects into the database $manager->persist($userActive); $manager->persist($userUnactive); $manager->flush(); } public function getOrder() { return 2; }}Code for Group Entity:/** * @ORM\ManyToMany(targetEntity="User", inversedBy="groups") */private $users;Code for User Entity:/** * @ORM\ManyToMany(targetEntity="Group", mappedBy="users") */protected $groups;Added Group Methos:/** * Add groups * * @param \Blogger\BlogBundle\Entity\groups $groups * @return User */public function addGroup(\Blogger\BlogBundle\Entity\groups $groups){ $this->groups[] = $groups; return $this;} 解决方案 The addGroup method has the wrong type hint:it should be:/** * Add groups * * @param \Blogger\BlogBundle\Entity\Group $groups * @return User */public function addGroup(\Blogger\BlogBundle\Entity\Group $groups){ $this->groups[] = $groups; return $this;}notice "\Blogger\BlogBundle\Entity\Group" instead of "\Blogger\BlogBundle\Entity\groups" 这篇关于如何从Doctrine Fixture参考获取实体？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
