Use ramsey/uuid as a Doctrine field type
, (*1)
, (*2)
The ramsey/uuid-doctrine package provides the ability to use
ramsey/uuid as a Doctrine field type., (*3)
This project adheres to a code of conduct.
By participating in this project and its community, you are expected to
uphold this code., (*4)
Installation
Install this package as a dependency using Composer., (*5)
``` bash
composer require ramsey/uuid-doctrine, (*6)
## Usage
### Configuration
To configure Doctrine to use ramsey/uuid as a field type, you'll need to set up
the following in your bootstrap:
``` php
\Doctrine\DBAL\Types\Type::addType('uuid', 'Ramsey\Uuid\Doctrine\UuidType');
In Symfony:, (*7)
``` yaml, (*8)
config/packages/doctrine.yaml
doctrine:
dbal:
types:
uuid: Ramsey\Uuid\Doctrine\UuidType, (*9)
In Zend Framework:
```php
<?php
// module.config.php
use Ramsey\Uuid\Doctrine\UuidType;
return [
'doctrine' => [
'configuration' => [
'orm_default' => [
'types' => [
UuidType::NAME => UuidType::class,
In Laravel:, (*10)
<?php
// config/doctrine.php
'custom_types' => [
\Ramsey\Uuid\Doctrine\UuidType::NAME => \Ramsey\Uuid\Doctrine\UuidType::class
],
In roave/psr-container-doctrine:, (*11)
<?php
use Ramsey\Uuid\Doctrine\UuidType;
return [
'doctrine' => [
'types' => [
UuidType::NAME => UuidType::class,
],
/* ... */
],
/* ... */
];
Mappings
Then, in your models, you may annotate properties by setting the #[Column]
type to uuid, and defining a custom generator of Ramsey\Uuid\UuidGenerator.
Doctrine will handle the rest., (*12)
``` php
use Doctrine\ORM\Mapping as ORM;
use Ramsey\Uuid\Doctrine\UuidGenerator;
use Ramsey\Uuid\UuidInterface;, (*13)
[ORM\Entity]
[ORM\Table(name: "products")]
class Product
{
#[ORM\Id]
#[ORM\Column(type: "uuid", unique: true)]
#[ORM\GeneratedValue(strategy: "CUSTOM")]
#[ORM\CustomIdGenerator(class: UuidGenerator::class)]
protected UuidInterface $id;, (*14)
public function getId(): UuidInterface
{
return $this->id;
}
}, (*15)
If you use the XML Mapping instead of PHP attributes.
``` xml
<id name="id" column="id" type="uuid">
<generator strategy="CUSTOM"/>
<custom-id-generator class="Ramsey\Uuid\Doctrine\UuidGenerator"/>
</id>
You can also use the YAML Mapping., (*16)
``` yaml
id:
id:
type: uuid
generator:
strategy: CUSTOM
customIdGenerator:
class: Ramsey\Uuid\Doctrine\UuidGenerator, (*17)
### Binary database columns
In the previous example, Doctrine will create a database column of type `CHAR(36)` if MariaDB / MySQL are in use,
but you may also use this library to store UUIDs as binary strings. The
`UuidBinaryType` helps accomplish this.
In your bootstrap, place the following:
``` php
\Doctrine\DBAL\Types\Type::addType('uuid_binary', 'Ramsey\Uuid\Doctrine\UuidBinaryType');
$entityManager->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('uuid_binary', 'binary');
In Symfony:, (*18)
``` yaml, (*19)
config/packages/doctrine.yaml
doctrine:
dbal:
types:
uuid_binary: Ramsey\Uuid\Doctrine\UuidBinaryType, (*20)
# mapping_types:
# uuid_binary: binary
Then, when annotating model class properties, use `uuid_binary` instead of `uuid`:
#[Column(type: "uuid_binary")]
### InnoDB-optimised binary UUIDs - deprecated
More suitable if you want to use UUIDs as primary key. Note that this can cause
unintended effects if:
* decoding bytes that were not generated using this method
* another code (that isn't aware of this method) attempts to decode the
resulting bytes
More information in this [Percona article][percona-optimized-uuids]
and [UUID Talk by Ben Ramsey][benramsey-com-uuid-talk] (starts at [slide 58][]).
``` php
\Doctrine\DBAL\Types\Type::addType('uuid_binary_ordered_time', 'Ramsey\Uuid\Doctrine\UuidBinaryOrderedTimeType');
$entityManager->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('uuid_binary_ordered_time', 'binary');
In Symfony:, (*21)
``` yaml, (*22)
config/packages/doctrine.yaml
doctrine:
dbal:
types:
uuid_binary_ordered_time: Ramsey\Uuid\Doctrine\UuidBinaryOrderedTimeType, (*23)
# mapping_types:
# uuid_binary_ordered_time: binary
Then, in your models, you may annotate properties by setting the `@Column`
type to `uuid_binary_ordered_time`, and defining a custom generator of
`Ramsey\Uuid\UuidOrderedTimeGenerator`. Doctrine will handle the rest.
``` php
#[Entity]
#[Table(name: "products")]´
class Product
{
#[Id]
#[Column(type: "uuid_binary_ordered_time", unique: true)]
#[GeneratedValue(strategy: "CUSTOM")]
#[CustomIdGenerator(class: UuidOrderedTimeGenerator::class)]
protected UuidInterface $id;
public function getId(): UuidInterface
{
return $this->id;
}
}
If you use the XML Mapping instead of PHP annotations., (*24)
``` xml
, (*25)
### InnoDB-optimised binary UUIDs - new way
With the introduction of new
[UUID types](https://www.ietf.org/archive/id/draft-peabody-dispatch-new-uuid-format-04.html)
(including sortable, unix epoch based UUID version 7) it is now recommended
to use regular `uuid_binary` with `Ramsey\Uuid\Doctrine\UuidV7Generator` for primary keys.
In your bootstrap, place the following:
``` php
\Doctrine\DBAL\Types\Type::addType('uuid_binary', 'Ramsey\Uuid\Doctrine\UuidBinaryType');
$entityManager->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('uuid_binary', 'binary');
In Symfony:, (*26)
``` yaml, (*27)
config/packages/doctrine.yaml
doctrine:
dbal:
types:
uuid_binary: Ramsey\Uuid\Doctrine\UuidBinaryType, (*28)
# mapping_types:
# uuid_binary: binary
Then, in your models, you may annotate properties by setting the `#[Column]`
type to `uuid_binary`, and defining a custom generator of
`Ramsey\Uuid\UuidV7Generator`. Doctrine will handle the rest.
``` php
#[Entity]
#[Table(name: "products")]
class Product
{
#[Id]
#[Column(type: "uuid_binary", unique: true)]
#[GeneratedValue(strategy: "CUSTOM")]
#[CustomIdGenerator(class: UuidV7Generator::class)]
protected UuidInterface $id;
public function getId(): UuidInterface
{
return $this->id;
}
}
If you use the XML Mapping instead of PHP annotations., (*29)
``` xml
, (*30)
### PostgreSQL considerations
If you are using PostgreSQL, Doctrine uses PostgreSQL's `uuid` for the `Ramsey\Uuid\Doctrine\UuidType` (`uuid`).
Therefor you don't need to use the `uuid_binary` / `uuid_binary_ordered_time` types when using PostgreSQL.
You can still use `UuidV7Generator::class` to optimize indexing though.
``` php
#[Entity]
#[Table(name: "products")]
class Product
{
#[Id]
#[Column(type: "uuid", unique: true)]
#[GeneratedValue(strategy: "CUSTOM")]
#[CustomIdGenerator(class: UuidV7Generator::class)]
protected UuidInterface $id;
public function getId(): UuidInterface
{
return $this->id;
}
}
Working with binary identifiers
When working with binary identifiers you may wish to convert them into a readable format.
As of MySql 8.0 you can use the BIN_TO_UUID and UUID_TO_BIN functions documented here.
The second argument determines if the byte order should be swapped, therefore when using uuid_binary you should pass 0
and when using uuid_binary_ordered_time you should pass 1., (*31)
For other versions you can use the following:, (*32)
``` sql
DELIMITER $$, (*33)
CREATE
FUNCTION BIN_TO_UUID(bin_uuid BINARY(16), swap_flag BOOLEAN)
RETURNS CHAR(36)
DETERMINISTIC
BEGIN
DECLARE hex_uuid CHAR(32);
SET hex_uuid = HEX(bin_uuid);
RETURN LOWER(CONCAT(
IF(swap_flag, SUBSTR(hex_uuid, 9, 8),SUBSTR(hex_uuid, 1, 8)), '-',
IF(swap_flag, SUBSTR(hex_uuid, 5, 4),SUBSTR(hex_uuid, 9, 4)), '-',
IF(swap_flag, SUBSTR(hex_uuid, 1, 4),SUBSTR(hex_uuid, 13, 4)), '-',
SUBSTR(hex_uuid, 17, 4), '-',
SUBSTR(hex_uuid, 21)
));
END$$, (*34)
CREATE
FUNCTION UUID_TO_BIN(str_uuid CHAR(36), swap_flag BOOLEAN)
RETURNS BINARY(16)
DETERMINISTIC
BEGIN
RETURN UNHEX(CONCAT(
IF(swap_flag, SUBSTR(str_uuid, 15, 4),SUBSTR(str_uuid, 1, 8)),
SUBSTR(str_uuid, 10, 4),
IF(swap_flag, SUBSTR(str_uuid, 1, 8),SUBSTR(str_uuid, 15, 4)),
SUBSTR(str_uuid, 20, 4),
SUBSTR(str_uuid, 25))
);
END$$, (*35)
DELIMITER ;, (*36)
