php - Doctrine 2 ManyToMany cascade -

is possible in doctrine 2 create 2 objects many many related , call persist on 1 of them save both?

user entity:

    /**  * owning side  *  * @manytomany(targetentity="role", inversedby="users", cascade={"persist"})  * @jointable(name="user_roles",  *      joincolumns={@joincolumn(name="user_id", referencedcolumnname="id")},  *      inversejoincolumns={@joincolumn(name="role_id", referencedcolumnname="id")}  *      )  */ public $roles; 

role entity:

    /**  * inverse side  *  * @manytomany(targetentity="user", mappedby="roles")  */ public $users; 

saving:

    $role = new role();      $user = new user();  $user->roles->add($role); $role->users->add($user);  $em->persist($user); $em->flush(); 

it doesn't work , trows error "a new entity found through relationship not configured cascade persist operations: entities\role@0000000004a29c11000000005c48cb75. explicitly persist new entity or configure cascading persist operations on relationship."

you should apply cascade={"persist"} role entity.

not expert on doctrine, think doctrine checks associated entity cascading options.

since cascading persist from users to roles, checks role entity if should persisted cascade.
