Use ramsey/uuid as a Doctrine field type
The ramsey/uuid-doctrine package provides the ability to use ramsey/uuid as a Doctrine field type.
This project adheres to a code of conduct. By participating in this project and its community, you are expected to uphold this code.
Installation
Install this package as a dependency using Composer.
Usage
Configuration
To configure Doctrine to use ramsey/uuid as a field type, you'll need to set up the following in your bootstrap:
In Symfony:
In Zend Framework:
In Laravel:
In roave/psr-container-doctrine:
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.
If you use the XML Mapping instead of PHP attributes.
You can also use the YAML Mapping.
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:
In Symfony:
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 and UUID Talk by Ben Ramsey (starts at slide 58).
In Symfony:
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.
If you use the XML Mapping instead of PHP annotations.
InnoDB-optimised binary UUIDs - new way
With the introduction of new
UUID types
(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:
In Symfony:
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.
If you use the XML Mapping instead of PHP annotations.
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.
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 you should pass 0 and when using you should pass 1.
For other versions you can use the following:
