Flask-RQ

RQ (Redis Queue) integration for Flask applications

Resources

https://secure.travis-ci.org/Birdback/flask-rq.png

Installation

$ pip install flask-rq

Getting started

To quicly start using rq, simply create an RQ instance:

from flask import Flask
form flask.ext.rq import RQ


app = Flask(__name__)

RQ(app)

@job decorator

Provides a way to quickly set a function as an rq job:

from flask.ext.rq import job


@job
def process(i):
    #  Long stuff to process


process.delay(3)

A specific queue name can also be passed as argument:

@job('low')
def process(i):
    #  Long stuff to process


process.delay(2)

get_queue function

Returns default queue or specific queue for name given as argument:

from flask.ext.rq import get_queue


job = get_queue().enqueue(stuff)  # Creates a job on ``default`` queue
job = get_queue('low').enqueue(stuff)  # Creates a job on ``low`` queue

get_worker function

Returns a worker for default queue or specific queues for names given as arguments:

from flask.ext.rq import get_worker


# Creates a worker that handle jobs in ``default`` queue.
get_worker().work(True)
# Creates a worker that handle jobs in both ``default`` and ``low`` queues.
get_worker('default', 'low').work(True)
# Note: These queues have to share the same connection

Configuration

By default Flask-RQ will connect to the default, locally running Redis server. One can change the connection settings for the default server like so:

app.config['RQ_DEFAULT_HOST'] = 'somewhere.com'
app.config['RQ_DEFAULT_PORT'] = 6479
app.config['RQ_DEFAULT_PASSWORD'] = 'password'
app.config['RQ_DEFAULT_DB'] = 1

Queue connection can also be set using a DSN:

app.config['RQ_LOW_URL'] = 'redis://localhost:6379/2'
