Symfony2+Doctrine - Validating one-to-many collect

问题:

I have a form to create a new entity. That entity has a collection of other entities that are also entered in that form.

I want to use the validation options of the entity in the collection to validate those entities but it does not work. The validation rules of the "main" entity (Person) are checked, but the validation rules of the entities in the addressList collection (Address) are not checked. When I input invalid information in the fields, the submitted form is successfully validated.

In this example, the annotation for street is not used on validation.

class Person 
{
    ...

    /**
     * @ORM\OneToMany(targetEntity="Address", mappedBy="owner", cascade={"persist", "detach"})
     */
    protected $addressList;

    ....
}

class Address
{
    ...
    /**
     * @ORM\ManyToOne(targetEntity="Person", inversedBy="addressList")
     * @ORM\JoinColumn(name="person_id", referencedColumnName="id", onDelete="CASCADE")
     */
    protected $owner;

    /**
     * @ORM\Column(type="string", length=75)
     * @Assert\MinLength(
     *     limit=3,
     *     message="Street must have atleast {{ limit }} characters."
     * )
     */
    protected $street;

    ...

}

How can I get the form to validate the supplied Address entities?

回答1:

I had the same problem but was solved with:

/**
 * @ORM\OneToMany(
 *  targetEntity="Entity",
 *  mappedBy="mappedEntity",
 *  cascade={"persist" , "remove"}
 * )
 * @Assert\Valid
 */

I use this:

use Symfony\Component\Validator\ExecutionContextInterface;

class Person 
{
...

/**
 * @ORM\OneToMany(targetEntity="Address", mappedBy="owner", cascade={"persist", "detach"})
 */
protected $addressList;

....

/**
 * @Assert\Callback
 */
public function validate(ExecutionContextInterface $context)
{
    if (!$this->getAddressList()->count()) {
        $context->addViolationAt(
            'addressList',
            'You must add at least one address',
            array(),
            null
        );
    }
}
}

Just add annotation assert like following

/** 
 * @Assert\Count(
 *      min = "1",
 *      minMessage = "You must specify at least one"
 * )
 * @Assert\Valid 
 * 
 */
protected $name_of_collection_property;

You could also use the "Valid" constraint with the "All" constraint :

/**
 * @ORM\OneToMany(targetEntity="Address", mappedBy="owner", cascade={"persist", "detach"})
 * @Assert\All({
 *     @Assert\Valid
 * })
 */

protected $addressList;
