Doctrine 3.3 No identifier found when #[Id] does exists

Doctrine is giving me this error because i dont have an #[Id]

No identifier/primary key specified for Entity "Event\Entity\Usuari". Every Entity must have an identifier/primary key.

The problem is that I do have the tags:

namespace Event\Entity;

use Doctrine\DBAL\Schema\Column;
use Doctrine\DBAL\Schema\Table;
use Doctrine\DBAL\Types\DateType;
use Doctrine\ORM\Mapping\Entity;
use Doctrine\ORM\Mapping\GeneratedValue;
use Doctrine\ORM\Mapping\Id;

#[Entity]
#[Table(name: 'Usuari')]
class Usuari{
    #[Id]
    #[Column(type: 'integer')]
    #[GeneratedValue]
    private int $id ;
    
    #[Column(type: 'varchar',length: 100 )]
    private string $name;
    
    #[Column(type: 'varchar',length: 150 )]
    private string $email;
    
    #[Column(type: 'varchar',length: 30 )]
    private string $phone;
    
    #[Column(type: 'datetime')]
    private DateType $createdAt;
    
}

Thats the whole project, i don't know why it dosn't work

Solution

You've got a few errors here:

The tags for Table and Column that you want are the ones in the Doctrine\Orm namespace, not the Doctrine\DBAL\Schema namespace.
The column type should be a DBAL type, not a specific database type. In this case, string and not varchar.
The DateType typehint that you've used should (probably) be a native DateTime instead.

So:

namespace Event\Entity;

use DateTime;
use Doctrine\ORM\Mapping\Column;
use Doctrine\ORM\Mapping\Entity;
use Doctrine\ORM\Mapping\GeneratedValue;
use Doctrine\ORM\Mapping\Id;
use Doctrine\ORM\Mapping\Table;

#[Entity]
#[Table(name: 'Usuari')]
class Usuari
{
    #[Id]
    #[Column(type: 'integer')]
    #[GeneratedValue]
    private int $id;

    #[Column(type: 'string',length: 100)]
    private string $name;

    #[Column(type: 'string',length: 150)]
    private string $email;

    #[Column(type: 'string',length: 30)]
    private string $phone;

    #[Column(type: 'datetime')]
    private DateTime $createdAt;
}

You could also do it like this:

namespace App\Entity;

use DateTime;
use Doctrine\ORM\Mapping as ORM;

#[ORM\Entity]
#[ORM\Table(name: 'Usuari')]
class Usuari
{
    #[ORM\Id]
    #[ORM\Column(type: 'integer')]
    #[ORM\GeneratedValue]
    private int $id;

    #[ORM\Column(type: 'string',length: 100)]
    private string $name;

    #[ORM\Column(type: 'string',length: 150)]
    private string $email;

    #[ORM\Column(type: 'string',length: 30)]
    private string $phone;

    #[ORM\Column(type: 'datetime')]
    private DateTime $createdAt;
}
