No project description provided

identityfield

Auto-incrementing fields like Django AutoField but without restrictions!

This reusable app provides fields that are using PostgreSQL GENERATED { ALWAYS | BY DEFAULT } AS IDENTITY. Same as Django AutoField. But without primary_key=true limitation.

Installation

• uv add django-identityfield
• add "identityfield" to your settings.INSTALLED_APPS

Usage

from django.db import models
from identityfield import IdentityField, Identity


class HappyModel(models.Model):
    sequence = IdentityField()
    # ALWAYS rejects any value other than DEFAULT in UPDATE
    always_sequence = IdentityField(identity=Identity.ALWAYS)

DB sequences are automatically created by PostgreSQL. And are automatically incremented on DB side.
