ModelQueue: Task Queue Based on Django Models
=============================================

`ModelQueue`_ is an Apache2 licenced task queue based on Django models.

.. warning::

   What you see here is a work-in-progress!

Here's what it looks like:

::

    # yourapp/models.py

    import modelqueue
    from django.db import models

    class Report(models.Model):
        upload = models.FileField()
        status = modelqueue.StatusField()
        # ^-- Add status field.

    # yourapp/management/commands/process_report_uploads.py

    import modelqueue, time
    from django.core.management.base import BaseCommand

    class Command(BaseCommand):

        def handle(self, *args, **options):
            while True:
                modelqueue.run(
                    Report.objects.all(),
                    # ^-- Queryset of models to process.
                    'status',
                    # ^-- Field name for model queue.
                    self.process,
                    # ^-- Callable to process model.
                )
                time.sleep(1)
                # ^-- Bring your own parallelism/concurrency.

        def process(self, report):
            pass  # Process report uploads.

ModelQueue is a hazardous project. It takes a bad idea and makes it easy and
effective. You may come to regret using your database as a task queue but it
won't be today!
