How should I handle Symfony2/Doctrine exceptions - php

Question

Maybe this is a hot topic and some others talk about this but I don't find a good solution yet to this problem. Take this error for UNIQUE fields as example. When I try to insert the same values to the database I get this error:
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry
'j1234567' for key 'UNIQ_FC3A5A1592FC23A8'
Of course this happens on app_dev.php (development) enviroment but I don't know how to deal with this in order to show an error page to users instead of this ugly error. I test the same code at production then the ugly error disappear but I get this instead:
ERROR: INTERNAL SERVER ERROR
Paths, I though, are more than one, for example I could check the existence of the record before I insert or before I send the request trough AJAX but I want to learn how to achieve this by using Symfony2 and Doctrine2 asserts. I have already added this code to my entities:
<?php
....
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
/**
* SysPerfil
*
* #ORM\Entity
* #ORM\Table(name="sys_perfil")
* #UniqueEntity(fields={"rif"}, message="Este RIF ya existe en nuestra base de datos")
* #UniqueEntity(fields={"ci"}, message="Este CI ya existe en nuestra base de datos")
* #UniqueEntity(fields={"nombre"}, message="Este nombre ya existe en nuestra base de datos")
*/
class SysPerfil
{
....
But it's not working since I get the error mentioned above, so what is the best way to handle this? Any ideas? Advices? Docs?
Add form types
Yes, I send the data trough a form type, see below:
public function buildForm(FormBuilderInterface $builder, array $options)
{
parent::buildForm($builder, $options);
$builder
->add('email', 'email', array(
'required' => true,
'label' => 'Email',
'trim' => true
))
->add('password', 'password', array(
'required' => true,
'label' => 'Contraseña',
'always_empty' => true
))
->add('confirm', 'password', array(
'required' => true,
'mapped' => false,
'label' => 'Verificar contraseña',
'always_empty' => true
))
->add('enabled', 'checkbox', array(
'required' => true,
'label' => 'Activo?',
'data' => true
))
->add('perfil', new AdminPerfilType());
}
And AdminPerfilType.php:
public function buildForm(FormBuilderInterface $builder, array $options)
{
parent::buildForm($builder, $options);
$builder
->add('persJuridica', 'choice', array(
'choices' => RifType::getChoices(),
'required' => true,
'label' => 'RIF',
'trim' => true,
'attr' => array(
'class' => 'persJuridica'
)
))
->add('roleType', 'choice', array(
'choices' => AdminRoleType::getChoices(),
'required' => true,
'label' => "Tipo de Usuario",
'trim' => true
))
->add('rif', 'text', array(
'required' => true,
'label' => false,
'trim' => true,
'attr' => array(
'class' => "numeric",
'maxlength' => 15
)
))
->add('ci', 'text', array(
'label' => 'CI',
'trim' => true,
'attr' => array(
'class' => "numeric ci",
'disabled' => 'disabled'
)
))
->add('nombre', 'text', array(
'required' => true,
'label' => 'Nombre',
'trim' => true
))
->add('apellido', 'text', array(
'required' => true,
'label' => 'Apellidos',
'trim' => true
));
}
If you're looking for validation rules inside the form then I haven't since I though that Doctrine/Symfony2 handle that part already

Answer 1

I guess your error is because you have a Parent -> Child Entities with One-To-One mapping, your form validation is checking the parent entity validation rules without checking the child validation rules because you are not using Assert\Valid
Example from Symfony Documentation http://symfony.com/doc/current/reference/constraints/Valid.html:
// src/Acme/HelloBundle/Entity/Address.php
namespace Acme\HelloBundle\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class Address
{
/**
* #Assert\NotBlank()
*/
protected $street;
/**
* #Assert\NotBlank
* #Assert\Length(max = "5")
*/
protected $zipCode;
}
// src/Acme/HelloBundle/Entity/Author.php
namespace Acme\HelloBundle\Entity;
class Author
{
/**
* #Assert\NotBlank
* #Assert\Length(min = "4")
*/
protected $firstName;
/**
* #Assert\NotBlank
*/
protected $lastName;
//without this Symfony won't check if the inserted address is satisfying the validation rules or not
/**
* #Assert\Valid
*/
protected $address;
}
