djrm

djrm packages Django's ORM, migration framework, and database backends as a standalone library. It keeps the retained Django APIs under the djrm import namespace and omits the web framework.

This is an independent fork. It is not an official Django Software Foundation project.

Installation

The distribution, Python import namespace, and command are all named djrm.

python -m pip install djrm

Release builds are published to PyPI. See Maintenance and releases for the release policy.

Included

• Models, fields, querysets, managers, expressions, and aggregations
• Schema migrations and data migrations
• SQLite, PostgreSQL, MySQL, and Oracle backends
• djrm.contrib.contenttypes and djrm.contrib.postgres
• Database-focused commands including makemigrations, migrate, showmigrations, dumpdata, and loaddata

HTTP handling, URL routing, views, middleware, templates, forms, auth, admin, sessions, static files, and other web-facing components are not included. The package does not provide a compatibility django namespace.

Minimal setup

import djrm
from djrm.conf import settings

settings.configure(
    DATABASES={
        "default": {
            "ENGINE": "djrm.db.backends.sqlite3",
            "NAME": ":memory:",
        }
    },
    DEFAULT_AUTO_FIELD="djrm.db.models.BigAutoField",
    INSTALLED_APPS=[],
)
djrm.setup()

Commands use the same settings conventions as Django:

export DJANGO_SETTINGS_MODULE=myproject.settings
djrm migrate
python -m djrm showmigrations

DJANGO_SETTINGS_MODULE keeps its upstream name. Only Python import paths move from django.* to djrm.*.

Development

Install uv, then run:

make install
make check
make test
make build
make check-dist

make test runs the package smoke tests and the retained SQLite ORM suite.

Maintenance and releases

main carries the currently supported Django LTS line. Production builds start from an exact official Django release tag and use SemVer:

Django 5.2.17 -> djrm 0.1.0
Django 6.2    -> djrm 1.0.0

djrm 0.x corresponds to Django 5.2 LTS, 1.x corresponds to Django 6.2 LTS, and each later LTS gets the next major. Within an LTS line, a newer Django patch tag increments the djrm minor; a djrm-only fix from the same tag increments the patch. The exact Django tag is recorded as release provenance. The update tool creates a separate worktree, performs the namespace conversion, applies the reviewed fork tree delta with a three-way merge, and stops for human review when upstream changed retained code incompatibly.

uv run python scripts/apply_django_lts.py \
  --django-ref 5.2.17 \
  --output ../djrm-5.2.17

See MAINTENANCE.md for the branch model, release gate, conflict workflow, and PyPI setup. SPEC.md defines the retained API.
