Symfony2 Override Constraints - php

Question

I have BaseEntity class:
class BaseEntity
{
/**
* The name.
*
* #var string
*
* #ORM\Column(name="name", type="string", length=255, unique=true, nullable=false)
* #Assert\Length(min=2, max=255, minMessage="default.name.short", maxMessage="default.name.long")
* #Assert\NotBlank(message = "default.name.not_blank")
*/
private $name;
}
and
class UserEntity extends BaseEntity
{
/**
* {#inheritDoc}
*
* #Assert\Length(min=2, max=255, minMessage="user.name.short", maxMessage="default.name.long")
* #Assert\NotBlank(message = "user.name.not_blank")
*/
private $name;
}
Now, When I post a new UserEntity into the form with long or short name Symfony gives me 2 errors: (for long:)
default.name.long
user.name.long
But I want it to show only ONE error, so :
- user.name.long
e.g. I want to override, but do not add another one

Answer 1

I think what you are looking for a validator group. So you can split up you validation rules into groups.
There is a excellent documentation about this feature:
http://symfony.com/doc/current/validation/groups.html

Answer 2

Maybe a Custom Validation Constraint could help you if you could (depending of your application logic) remove those two validations and make your own.
Something like this maybe?
http://symfony.com/doc/current/cookbook/validation/custom_constraint.html

Answer 3

If you're happy to set up at least some of your validation rules via a YAML file rather than annotations, you can override the base class's validation settings without needing to edit the class file itself.
Your YAML file would look something like this and would need to be in a location like src/YourApp/YourBundle/Resources/config/validation.yml to be picked up automatically:
BaseEntity:
properties:
name:
- NotBlank:
message: user.name.not_blank
- Length:
min: 2
minMessage: user.name.short
max: 255
maxMessage: default.name.long
If you want to put your validation file in a non-standard location, see https://stackoverflow.com/a/24210501/328817
