Hi Greg, I think the Valid constraint is for a different purpose. See: http://symfony.com/doc/2.0/reference/constraints/Valid.html.
I think you're right about a Comparison validation being common. One way it could work is with a series of CLASS_CONSTRAINT constraints (GreatherThan, LessThan, LessThanOrEqual, etc). So for the moment it would require a custom constraint (http://symfony.com/doc/2.0/cookbook/ validation/custom_constraint.html). A rough outline of the solution (I haven't tested this so might have some errors): ----------------------------------------------------- namespace MyProject\Validator\Constraint; use Symfony\Component\Validator\Constraint; class LessThan extends Constraint { public $message = 'First value is not less than second value'; public $firstProperty; public $secondProperty; public function getRequiredOptions() { return array('firstProperty', 'secondProperty'); } public function getTargets(){ return self::CLASS_CONSTRAINT; } } ----------------------------------------------------- namespace MyProject\Validator; use Symfony\Component\Validator\ConstraintValidator; use Symfony\Component\Validator\Constraint; class LessThanValidator extends ConstraintValidator { public function isValid($value, Constraint $constraint) { $firstValue = $value->{'get' . strtoupper($constraint- >firstProperty)}(); $secondValue = $value->{'get' . strtoupper($constraint- >secondProperty)}(); if ($firstValue >= $secondValue) { $this->setMessage($constraint->message); return false; } return true; } } ---------------------------------------------- /** * @myAssert:LessThan(firstProperty="time1", secondProperty="time2") */ class MyDomainObject { private $time1; private $time2; public function getTime1() { return $this->time1; } public function getTime2() { return $this->time2; } } ---------------------------------------------- config.yml ---------------------------------------------- framework: ... validation: ... annotations: namespaces: myAssert: MyProject\Validator\Constraint\ ---------------------------------------------- Daniel On May 3, 9:04 am, Greg Militello <g...@thinkof.net> wrote: > Hey all, > I am not seeing a good way to use the annotation system in my case: > I am storing 2 times (however I could easily see storing two values of ANY > type), and I need to ensure that time_a is less than or equal to time_b. > > To be more specific, I am planning to store a time range.
