django-celery-model is an extension to Celery which adds support for tracking Celery tasks assigned to Django model instances.
Install the latest version from pypi.python.org:
pip install django-celery-model
Install the development version by cloning the source from github.com:
pip install git+https://github.com/mback2k/django-celery-model.git
Add the package to your INSTALLED_APPS:
INSTALLED_APPS += (
'djcelery_model',
)
Make sure that you are receiving Celery events via:
CELERY_TASK_TRACK_STARTED = True
CELERY_TASK_SEND_SENT_EVENT = True
CELERY_SEND_EVENTS = True
Add the TaskMixin to your Django model:
from django.db import models
from django.utils.translation import ugettext_lazy as _
from djcelery_model.models import TaskMixin
class MyModel(TaskMixin, models.Model):
name = models.CharField(_('Name'), max_length=100)
Queue an asynchronous task from your Django model instance:
from .models import MyModel
from .tasks import mytask
mymodel = MyModel.objects.get(name='test instance')
mymodel.apply_async(mytask, ...)
Retrieve list of asynchronous tasks assigned to your Django model instance:
mymodel.tasks.all()
mymodel.tasks.pending()
mymodel.tasks.started()
mymodel.tasks.retrying()
mymodel.tasks.failed()
mymodel.tasks.successful()
mymodel.tasks.running()
mymodel.tasks.ready()
Check for a running or ready asynchronous task for your Django model instance:
mymodel.has_running_task
mymodel.has_ready_task
Handle asynchronous task results for your Django model instance:
mymodel.get_task_results()
mymodel.get_task_result(task_id)
mymodel.clear_task_results()
mymodel.clear_task_result(task_id)
Filter your Django model based upon asynchronous tasks:
MyModel.objects.with_tasks()
MyModel.objects.with_pending_tasks()
MyModel.objects.with_started_tasks()
MyModel.objects.with_retrying_tasks()
MyModel.objects.with_failed_tasks()
MyModel.objects.with_successful_tasks()
MyModel.objects.with_running_tasks()
MyModel.objects.with_ready_tasks()
MyModel.objects.without_tasks()
MyModel.objects.without_pending_tasks()
MyModel.objects.without_started_tasks()
MyModel.objects.without_retrying_tasks()
MyModel.objects.without_failed_tasks()
MyModel.objects.without_successful_tasks()
MyModel.objects.without_running_tasks()
MyModel.objects.without_ready_tasks()
