问题:
I use:
- Celery
- Django-Celery
- RabbitMQ
I can see all my tasks in the Django admin page, but at the moment it has just a few states, like:
- RECEIVED
- RETRY
- REVOKED
- SUCCESS
- STARTED
- FAILURE
- PENDING
It's not enough information for me. Is it possible to add more details about a running process to the admin page? Like progress bar or finished jobs counter etc.
I know how to use the Celery logging function, but a GUI is better in my case for some reasons.
So, is it possible to send some tracing information to the Django-Celery admin page?

I am starting to try figuring this out myself. Start by defining a PROGRESS state exactly as explained on the Celery userguide, then all you need is to insert a js in your template that will update your progress bar.

Here's my minimal progress-reporting Django backend using your setup. I'm still a Django n00b and it's the first time I'm messing with Celery, so this can probably be optimized.
from time import sleep from celery import task, current_task from celery.result import AsyncResult from django.http import HttpResponse, HttpResponseRedirect from django.core.urlresolvers import reverse from django.utils import simplejson as json from django.conf.urls import patterns, url @task() def do_work(): """ Get some rest, asynchronously, and update the state all the time """ for i in range(100): sleep(0.1) current_task.update_state(state='PROGRESS', meta={'current': i, 'total': 100}) def poll_state(request): """ A view to report the progress to the user """ if 'job' in request.GET: job_id = request.GET['job'] else: return HttpResponse('No job id given.') job = AsyncResult(job_id) data = job.result or job.state return HttpResponse(json.dumps(data), mimetype='application/json') def init_work(request): """ A view to start a background job and redirect to the status page """ job = do_work.delay() return HttpResponseRedirect(reverse('poll_state') + '?job=' + job.id) urlpatterns = patterns('webapp.modules.asynctasks.progress_bar_demo', url(r'^init_work$', init_work), url(r'^poll_state$', poll_state, name="poll_state"), )

Thank @Florian Sesser for your example!
I made a complete Django app that show the progress of create 1000 objects to the users at http://iambusychangingtheworld.blogspot.com/2013/07/django-celery-display-progress-bar-of.html
Everyone can download and use it!
