设置用户实体的默认角色

Question

新用户注册时，如果未设置角色，则自动设置默认角色（层次结构中最低的角色）。我已经通过迁移创建了“多对多”关系，并具有三个表：用户，角色， user_roles 。因此，主要目标是在user_roles中为每个用户至少拥有一个关系。

下面列出了用户和角色的实体 用户实体

<?php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;

class User implements UserInterface
{
    public function __construct()
    {
        $this->roles = new ArrayCollection();
    }

    /**

    private $lastname;


    /**

    private $roles;

    public function getId(): ?int
    {
        return $this->id;
    }

    public function getUsername(): ?string
    {
        return $this->username;
    }

    public function setUsername(string $username): self
    {
        $this->username = $username;

        return $this;
    }

    public function getPassword(): ?string
    {
        return $this->password;

    public function setPassword(string $password): self
    {
        $this->password = $password;

    public function setEmail(string $email): self
    {
        $this->email = $email;

        return $this;

    public function getFirstname(): ?string
    {
        return $this->firstname;

    public function setFirstname(string $firstname): self
    {
        $this->firstname = $firstname;

        return $this;

    public function getLastname(): string
    {
        return $this->lastname;
    }

    public function setLastname(string $lastname): self
    {
        $this->lastname = $lastname;

        return $this;
    }

    /**
     * @return array

    public function getRoles(): array
    {
        return $this->roles->toArray();
    }

    /**
     * @param Roles $role
     * @return $this
     */
    public function addRole(Roles $role) : self
    {
        if(!$this->roles->contains($role)) {
            $this->roles[] = $role;
        }
        return $this;
    }

    /**

     * @return $this
     */
    public function deleteRole(Roles $role) : self
    {
        if($this->roles->contains($role)) {
            $this->roles->removeElement($role);
        }
        return $this;
    }
}

角色实体：

<?php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;
use App\Repository\RolesRepository;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Annotation\Groups;

/**
 * @ApiResource(
 *     normalizationContext={
 *          "groups"={"read"}
 *     }
 * )
 * @ORM\Entity(repositoryClass=RolesRepository::class)
 */
class Roles
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=50)
     * @Groups({"read"})
     */
    private $sysName;

    /**
     * @ORM\Column(type="string", length=50)
     */
    private $name;

    /**
     * @ORM\ManyToMany(targetEntity="App\Entity\User", mappedBy="roles")
     */
    private $users;

    public function getId(): ?int
    {
        return $this->id;
    }

    public function getSysName(): ?string
    {
        return $this->sysName;
    }

    public function setSysName(string $sysName): self
    {
        $this->sysName = $sysName;

        return $this;
    }

    public function getName(): ?string
    {
        return $this->name;
    }

    public function setName(string $name): self
    {
        $this->name = $name;

        return $this;
    }
}

如果您不希望每个默认用户都拥有关系，则可以通过添加默认角色来扩展getRoles()方法。 我在一个项目中做了类似的事情，看起来像这样：

public function getRoles()
{
    if (count($this->getRole())) {
        foreach ($this->getRole() as $role) {
            $roles[] = $role->getRole();
        }
    } else {
        $roles = ['ROLE_USER'];
    }
    return $roles;
}
