类型错误：传递给Doctrine \ Common \ Collections \ ArrayCollection :: __ construct（）的参数1必须是类型数组，对象为

Question

实际上...或多或少我知道我的问题在哪里。 我在特定的控制器中收到此错误，我尝试persist($object) ...

实际上我正在开发一个网络应用程序，让我可以注册我正在阅读的所有书籍。我使用Google Books API。所以，我有下一个实体：

• 管理
• 用户
• 图书
• 类别

我正在考虑db，我想要一张user_id, book_id的表格 所以我决定做一个ManyToMany但是，我不知道这是不是...... (Because my familiars are going to use it)

必须像许多用户可以拥有相同的书一样，并且用户可以有很多书。

所以，我猜错了，因为我在ManyToMany... Controller和Entities下面写的/** * @ORM\Entity * @ORM\Table(name="Users") * @ORM\Entity(repositoryClass="UsersRepository") * @UniqueEntity("username") * @UniqueEntity("email") */ class Users implements UserInterface, \Serializable { /** * @ORM\Column(type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @ORM\Column(type="text") * @Assert\NotBlank() */ private $name; /** * @ORM\Column(type="text") * @Assert\NotBlank() */ private $lastname; /** * @ORM\Column(type="text") * @Assert\NotBlank() */ private $username; /** * @ORM\Column(type="string", length=255, unique=true) * @Assert\NotBlank() * @Assert\Email() */ private $email; /** * * @Assert\Length(max=4096) */ private $plainPassword; /** * * @ORM\Column(type="string", length=64) */ private $password; /** * @ORM\Column(type="text") * @Assert\NotBlank() */ private $language; /** * @ORM\Column(type="boolean") */ private $isActive; /***************** * Users constructor. */ public function __construct() { $this->language = 'es'; $this->isActive = true; } /** * @return mixed */ public function getId() { return $this->id; } /** * @param mixed $id */ public function setId($id) { $this->id = $id; } /** * @return mixed */ public function getName() { return $this->name; } /** * @param mixed $name */ public function setName($name) { $this->name = $name; } /** * @return mixed */ public function getLastname() { return $this->lastname; } /** * @param mixed $lastname */ public function setLastname($lastname) { $this->lastname = $lastname; } /** * @return mixed */ public function getUsername() { return $this->username; } /** * @param mixed $username */ public function setUsername($username) { $this->username = $username; } /** * @return mixed */ public function getEmail() { return $this->email; } /** * @param mixed $email */ public function setEmail($email) { $this->email = $email; } /** * @return mixed */ public function getPlainPassword() { return $this->plainPassword; } /** * @param mixed $plainPassword */ public function setPlainPassword($plainPassword) { $this->plainPassword = $plainPassword; } /** * @return mixed */ public function getPassword() { return $this->password; } /** * @param mixed $password */ public function setPassword($password) { $this->password = $password; } /** * @return mixed */ public function getLanguage() { return $this->language; } /** * @param mixed $language */ public function setLanguage($language) { $this->language = $language; } /** * @return mixed */ public function getIsActive() { return $this->isActive; } /** * @param mixed $isActive */ public function setIsActive($isActive) { $this->isActive = $isActive; } //implementaciones de la interface public function getSalt() { // you *may* need a real salt depending on your encoder // see section on salt below return null; } public function getRoles() { return array('ROLE_USER'); } public function eraseCredentials() { } /** @see \Serializable::serialize() */ public function serialize() { return serialize(array( $this->id, $this->username, $this->password, $this->isActive, )); } /** @see \Serializable::unserialize() */ public function unserialize($serialized) { list ( $this->id, $this->username, $this->password, $this->isActive, ) = unserialize($serialized); } } 没有很好地完成。 }

Answer 1

否$book->setUsers($user);，但$book->addUser($user);

而且，通常，方法setUsers无效

public function setUsers(Users $users = null)
{
    $this->users = $users;
}

在构造函数中初始化后，不得重新定义此属性。您只能添加或删除元素，但分配新值将破坏原则的功能。
