Doctrine migration ignores @Table Annotation in @Entity definition

Question

I have the following Doctrine Entity in Symfony 4.2:

When I run the migration the unique constraints and the indexes are not generated. The result of the Entity are just the following indexes in MySql:

• PRIMARY (id)
• identifier (identifier), Unique

Media.php

<?php 
// src/Entity/Media.php
namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Mapping\UniqueConstraint;

/**
 * Common\Model\Entity\Media
 *
 * @Entity
 * @Table(name="media", 
 *    uniqueConstraints={
 *        @UniqueConstraint(name="virtual_unique", 
 *            columns={"virtualname", "virtualfolder"})
 *    }
 *    indexes={
 *        @Index(name="idx_virtual", columns={"virtualname", "virtualfolder"})
 *        @Index(name="idx_identifier", columns={"identifier"}) 
 *    }
 * )
 */

/**
 * @ORM\Entity(repositoryClass="App\Repository\MediaRepository")
 */
class Media
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string", nullable=true, options={"unique": true})
     */
    private $identifier;

    /**
     * @ORM\Column(type="string", length=255, nullable=false)
     */
    private $virtualname;

    /**
     * @ORM\Column(type="string", length=255, nullable=true)
     */
    private $virtualfolder;
}

Probably you need change @Table to @ORM\\Table and remove @Entity

try this:

/**
 * @ORM\Entity(repositoryClass="App\Repository\MediaRepository")
 * @ORM\Table(name="media", 
 *    uniqueConstraints={
 *        @UniqueConstraint(name="virtual_unique", 
 *            columns={"virtualname", "virtualfolder"})
 *    }
 *    indexes={
 *        @ORM\Index(name="idx_virtual", columns={"virtualname", "virtualfolder"})
 *        @ORM\Index(name="idx_identifier", columns={"identifier"}) 
 *    }
 * )
 */

First, you have multiple annotation blocks for the same class. Just merge them and have a single annotation block for that entity.

And you are using serveral annotations directly, but not importing their definitions . Specifically:

• @Entity
• @Index
• @UniqueConstraint
• @Table

Either you:

Use them prefixed by @ORM (since you are doing use Doctrine\\ORM\\Mapping as ORM )

This is the most convenient and the one that's usually applied.

A complete fix:

/**
 * Common\Model\Entity\Media
 *
 * @ORM\Entity(repositoryClass="App\Repository\MediaRepository")
 * @ORM\Table(name="media", 
 *    uniqueConstraints={
 *        @ORM\UniqueConstraint(name="virtual_unique", 
 *            columns={"virtualname", "virtualfolder"})
 *    },
 *    indexes={
 *        @ORM\Index(name="idx_virtual", columns={"virtualname", "virtualfolder"}),
 *        @ORM\Index(name="idx_identifier", columns={"identifier"}) 
 *    }
 * )
 */
class Media
{}

Or, you use the full namespace declaration in those annotations

You could also use the annotations with the full namespace, like @Doctrine\\ORM\\Mapping\\Table , @Doctrine\\ORM\\Mapping\\UniqueConstraint , etc; but that gets unnecessarily verbose very quickly.

Or, you could import each of the annotations independently

use Doctrine\ORM\Mapping\Table;
use Doctrine\ORM\Mapping\Index;
use Doctrine\ORM\Mapping\Entity;
use Doctrine\ORM\Mapping\UniqueConstraint;

But it also seems wasteful.

---

The approach you'll see on the docs is the first one. Import Doctrine\\ORM\\Mapping as ORM , and use the annotations hanging from there.

Clearing my cache did the trick for me.

I tried a few other suggestions, but after a cache:clear I got the index in my migration.
