Symfony 2.2 Doctrine2多对多关系插入查询

Question

I'm using Doctrine2 in Symfony 2.2. I have the following entities:

1. "User"
2. "OrganizationSupplier"

and m:n relation between those entities. Here is how it is in schema:

class User {
.....
    /**
     * @ORM\ManyToMany(targetEntity="OrganizationSupplier", inversedBy="users")
     * @ORM\JoinTable(name="User_Supplier",
     *      inverseJoinColumns={@ORM\JoinColumn(name="organization_supplier_id", referencedColumnName="id")},
     *      joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")}
     *      )
     */
    private $allowed_suppliers;
.....
}

and

class OrganizationSupplier
{
...
    /**
     * @ORM\ManyToMany(targetEntity="User", mappedBy="allowed_suppliers")
     */
    private $users;
...
}

Here is m:n table created by Doctrine:

CREATE TABLE `User_Supplier` (
  `user_id` int(11) NOT NULL,
  `organization_supplier_id` int(11) NOT NULL,
  PRIMARY KEY (`user_id`,`organization_supplier_id`),
  KEY `IDX_31AFA1DDA76ED395` (`user_id`),
  KEY `IDX_31AFA1DD1A81C9F7` (`organization_supplier_id`),
  CONSTRAINT `FK_31AFA1DD1A81C9F7` FOREIGN KEY (`organization_supplier_id`) REFERENCES `organizationsupplier` (`id`),
  CONSTRAINT `FK_31AFA1DDA76ED395` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

Here is the data for user id=638 from this m:n table:

user_id organization_supplier_id
638 618
638 620
638 622
638 624
638 626
638 628
638 630
638 632
638 634
638 636

Everything is fine up to this point.

Now the problem: I have a form in admin that modifies this m:n table by adding/removing records from it. From business logic perspective I need to assign/unassign suppliers to certain users from the list of suppliers assigned to organization (OrgaizationSupplier entity - see above)

Here is the code for this field of the form:

->add('allowed_suppliers', 'entity', array('class'=>'STMainBundle:OrganizationSupplier', 'multiple'=>true, 'expanded'=>true,
        'query_builder' => function(EntityRepository $er) use ($user) {
            return $er->createQueryBuilder('os')
                ->where('os.organization = :organization')
                ->setParameter(':organization', $user->getOrganization());

If I submit it with a checkbox checked, I'm getting an SQL exception, it tries to launch a query with swapped columns:

INSERT INTO User_Supplier (organization_supplier_id, user_id) VALUES (?, ?)' with params [638, 618]: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`sollod_new`.`user_supplier`, CONSTRAINT `FK_31AFA1DDA76ED395` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`))".

so it should be vice versa, [618, 638] and not as it tries [638,618].

I'm a newbie in symfony, so I'm trying to find the place where it builds this query on postack, to control this parameters order.

Does anyone know where I can find it?

UPDATE: Here is ladybug dump of Request, User entity and Form. This is done right after $form->bind($request);

Thanks a lot

UPDATE: My bad, I forgot that schema is cached as well, the schema that I gave above was already the correct and fixed one:

 *      inverseJoinColumns={@ORM\JoinColumn(name="organization_supplier_id", referencedColumnName="id")},
 *      joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")}

Initially these columns were swapped. I only had to clear dev/prod cache to make it work. Sorry about that

Answer 1

It was a matter of cache. Initially the data model was wrong, I fixed it to be:

     *      inverseJoinColumns={@ORM\JoinColumn(name="organization_supplier_id", referencedColumnName="id")},
     *      joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")}

and forgot to clear cache
