Django-RMQ

Django-RMQ provides RabbitMQ wrappers and tools for Django projects, built on top of Pika. It is a lightweight integration layer — not a task queue or a Celery replacement — for projects that need to publish and consume messages while keeping broker infrastructure code predictable and close to the Django configuration. Supports RabbitMQ 3.13–4.3.

Features

• Django-native settings — configure broker connections via RABBITMQ_CONNECTIONS in settings.py, one entry per alias.
• Producer and Consumer wrappers — thin classes over Pika's blocking connection that handle channel lifecycle and lazy queue declaration.
• Decorator-style publishing — use a Producer instance as a @producer decorator to auto-publish a function's return value.
• Reliable delivery — publisher confirms, mandatory=True, and delivery_mode=2 (persistent) are enforced on every message.
• Auto-reconnect with backoff — producers retry once on transient channel errors; consumers reconnect with exponential backoff capped at a configurable maximum.
• Dead-letter routing — declare queues with QueueConfig(dead_letter_exchange=...) so unhandled messages are nacked without requeue and routed to a DLX.
• Management commands — setup_rabbitmq_topology (idempotent exchange/queue/binding setup) and start_consumers (threaded runner with graceful SIGTERM/SIGINT shutdown).
• Multiple connections — configure several broker aliases and select per producer/consumer via using=.
• Fully typed — ships py.typed; compatible with pyrefly and standard type checkers.

Installation

pip install django-rmq

Add 'django_rmq' to INSTALLED_APPS and configure at least one connection alias:

INSTALLED_APPS = [
    # ...
    'django_rmq',
]

RABBITMQ_CONNECTIONS = {
    'default': {
        'HOST': 'localhost',
        'PORT': 5672,
        'VIRTUAL_HOST': '/',
        'USER': 'guest',
        'PASSWORD': 'guest',
        'HEARTBEAT': 600,
        'BLOCKED_CONNECTION_TIMEOUT': 300,
        'RECONNECT_INITIAL_BACKOFF': 1.0,
        'RECONNECT_MAX_BACKOFF': 30.0,
    },
}

Quick start

Publish a message:

from django_rmq.producer import Producer

Producer(queue='orders').publish(body='{"order_id": 42}')

Consume messages (e.g. myapp/consumers.py):

from pika.adapters.blocking_connection import BlockingChannel
from pika.spec import Basic, BasicProperties

from django_rmq.consumer import Consumer
from django_rmq.registries.registry import get_consumers_registry

consumer: Consumer = Consumer(queue='orders')


@consumer
def handle_order(
    ch: BlockingChannel,
    method: Basic.Deliver,
    props: BasicProperties,
    body: bytes,
) -> None:
    print(body)
    ch.basic_ack(delivery_tag=method.delivery_tag)


get_consumers_registry().register(consumer=consumer)

Import consumers.py inside your app's AppConfig.ready(), then start consuming:

uv run python manage.py start_consumers

Testing

Unit tests

Unit tests mock pika and need no broker. They run by default — integration tests are marked integration and deselected:

uv run pytest

Integration tests

Integration tests run against a real RabbitMQ broker. The repo ships a .github/docker-compose.yml that starts the same image CI uses (with the management plugin the suite needs on port 15672). Connection params are read from RMQ_* env vars (defaults: localhost:5672, guest/guest, vhost /), which already match the Compose service:

docker compose -f .github/docker-compose.yml up -d --wait    # start the broker, block until healthy
uv run pytest -m integration
docker compose -f .github/docker-compose.yml down            # stop it when done

The suite isolates itself with per-test uuid-suffixed queues/exchanges and cleans them up, so it is safe against a shared broker (use a dedicated vhost).
