Installation

Installation using pip::

pip install django-smalluuid

Tested on:

  • Django >= 2.2 <= 4.0
  • Python 3.7, 3.8, 3.9, 3.10

Basic Usage

To get started use the SmallUUIDField field in your model definitions:

.. code-block:: python

from django.db import models
from django_smalluuid.models import SmallUUIDField, uuid_default

class ExampleModel(models.Model):
    uuid = SmallUUIDField(default=uuid_default())

The field provides values as instances of SmallUUID (see smalluuid_):

.. code-block:: python

>>> obj = ExampleModel.objects.create()

# The initial UUID has been auto-generated by uuid_default()
>>> obj.uuid
SmallUUID('T1q_P6HcQNSyW6tpqJTxww')

# It is still available in the groupex hex form (if needed)
>>> obj.hex_grouped
'4f5abf3f-a1dc-40d4-b25b-ab69a894f1c3'

# Filtering is done on the shortened UUIDs
>>> ExampleModel.objects.filter(uuid='T1q_P6HcQNSyW6tpqJTxww')
[<ExampleModel: ExampleModel object>]

Typed Usage

django-smalluuid also supports the Typed UUID's as provided by smalluuid_. This allows for the object's type to be stored within the UUID.

Updating the above example:

.. code-block:: python

from django.db import models
from django_smalluuid.models import SmallUUIDField, uuid_typed_default

class TypedExampleModel(models.Model):
    uuid = SmallUUIDField(default=uuid_typed_default(type=42))

Which can be interacted with as follows:

.. code-block:: python

>>> obj = TypedExampleModel.objects.create()
>>> obj.uuid
TypedSmallUUID('qvyk8nzbQfu8zAnTPQweyw')
>>> obj.uuid.type
42
