使用ON DELETE CASCADE在Symfony 2和Doctrine 2中创建架构

Question

I have some cross table between User table and Role table. I want to create cascade removing on the database level. I have the next annotation:

/**
 * @ORM\ManyToMany(targetEntity="Role")
 * @ORM\JoinTable(name="user_x_role",
 *     joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")},
 *     inverseJoinColumns={@ORM\JoinColumn(name="role_id", referencedColumnName="id")}
 * )
 * @var ArrayCollection $roles
 */
protected $roles;

But foreign keys have ondelete=restrict and onupdate=restrict after:

doctrine:schema:update --force

How can I change these values to CASCADE?

Answer 1

You should try this, don't forget to modify also the cascade on ORM level.

/**
 * @ORM\ManyToMany(targetEntity="Role", cascade={"persist","remove"})
 * @ORM\JoinTable(name="user_x_role",
 *     joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id", onDelete="CASCADE")},
 *     inverseJoinColumns={@ORM\JoinColumn(name="role_id", referencedColumnName="id", onDelete="CASCADE")},
 * )
 * @var ArrayCollection $roles
 */
protected $roles;
