Creating a custom validator as a service in Symfony2 - validation

Question

I'm trying to send an EntityManager object to my custom validator. For that, I created a service and defined the entity manager as an argument.
The problem is that the argument isn't sent to the validator, it fires an error in the __construct() function indicating that no arguments have been passed.
This is the definition of my service:
dinamic.shop.validator.deliverydate:
class: Dinamic\ShopBundle\Validator\Constraints\DeliveryDateValidator
arguments:
- #doctrine.orm.entity_manager
tags:
- { name: validator.constraint_validator, alias: deliverydate }
Here is the validateBy() method of my Constraint:
class DeliveryDate extends Constraints
{
...
public function validateBy()
{
return 'deliverydate';
}
}
Here is my ConstraintValidator:
Finally, this is how I set the constraint on the field. The field is not mapped to any entity:
->add('deliveryday', 'date', array(
'label' => 'Día de entrega',
'widget' => 'single_text',
'format' => 'dd/MM/yyyy',
'constraints' => array(
new NotBlank(),
new DeliveryDate($deliveryDateOptions),
),
)
)
I think that my error is in the FormType class, where I set the constraint on the field, but I can't find any examples of non-mapped fields.
I'm using Symfony2.3, any help will be appreciated, thanks a lot.
[EDIT]
I've used the command "sudo php app/console container:debug | grep validator" and the service I've created appears on the results
dinamic.shop.validator.deliverydate container Dinamic\ShopBundle\Validator\Constraints\DeliveryDateValidator

Answer 1

It's very likely one of those syntax issues!
The syntax can be this:
dinamic.shop.validator.deliverydate:
class: Dinamic\ShopBundle\Validator\Constraints\DeliveryDateValidator
arguments: [#doctrine.orm.entity_manager]
tags:
- { name: validator.constraint_validator, alias: deliverydate }
or this:
dinamic.shop.validator.deliverydate:
class: Dinamic\ShopBundle\Validator\Constraints\DeliveryDateValidator
arguments:
entityManager: "#doctrine.orm.entity_manager"
tags:
- { name: validator.constraint_validator, alias: deliverydate }
Note: To check if the service you're passing exists:
php app/console container:debug | grep doctrine
Will give you:
....
doctrine.orm.entity_manager n/a alias for doctrine.orm.default_entity_manager
....

I found the error. The problem was the function 'validateBy', it should have been validatedBy()
So the only change I needed to do was to change said function.
Thank you for the help #Patt
