TYPO3.Flow

Currently (afaik), the only option to set a validator to a model property is to annotate it in the vicinity of the appropriate method property:

 1     /**
 2      * @FLOW3\Validate(type="NotEmpty")
 3      * @FLOW3\Validate(type="RegularExpression", options={ "regularExpression"="/^[mf]$/" })
 4      * @var string
 5      * @ORM\Column(length=1)
 6      */
 7     protected $gender;
 8 
 9     /**
10      * @FLOW3\Validate(type="NotEmpty")
11      * @var \TYPO3\Party\Domain\Model\PersonName
12      * @ORM\OneToOne
13      */
14     protected $name;

I now have two additional options in mind, one would be via Configuration.yaml (or maybe even an additional Validation.yaml:

 1 -
 2   property: \Acme\Northwind\Person.gender
 3   validators:
 4     - NotEmpty
 5     - RegularExpression
 6         options:
 7           regularExpression: /^[mf]$/
 8 -
 9   property: \TYPO3\Party\Domain\Model\PersonName.firstName
10   validators:
11     - NotEmpty
12     - StringLength
13         options:
14           minimumLength: 2
15 
16 -
17   #dito for .lastName

Second would be to allow "deep" annotating via the parameter we already know from method argument annotation:

1     /**
2      * @FLOW3\Validate(type="NotEmpty")
3      * @FLOW3\Validate("$firstName", type="NotEmpty")
4      * @FLOW3\Validate("$lastName", type="NotEmpty")
5      * @var \TYPO3\Party\Domain\Model\PersonName
6      * @ORM\OneToOne
7      */
8     protected $name;

(for this example, remember \TYPO3\Party\Domain\Model\PersonName has properties firstName and lastName).
