Django Celery Error

I'm been trying to schedule a task for celery to do at the background but I keep encountering issues.

Quick reference on what I've done so far

I installed celery and django-celery via easy_install, added to INSTALLED_APPS:

'djcelery',
'kombu.transport.django',

imported the following and ran syncdb:

 import djcelery
 djcelery.setup_loader()
 BROKER_URL = "django://"

The task I'm trying to run in the background is password reset. So when a user forget his password , I want to make the sending email task run in the background so what I done is I moved my forgot_password function from views.py into tasks.py so it can run.

My tasks.py:

 from django.contrib.auth.views import password_reset
 from django.shortcuts import render
 from celery.decorators import task

 @task()
 def forgot_password(request):
     if request.method == 'POST':
         return password_reset(request,
             from_email=request.POST.get('email'))
     else:
         return render(request, 'forgot_password.html')

Their nothing in views.py now.

The problem is even though, I can send email if I lose my password. I'm not sure if it's running in the background. What I did to check is was:

 manage.py celery worker --loglevel=info

but I get an error: KeyError: 'processName':

 C:\o\17\mysite>manage.py celery worker --loglevel=info

Can someone please kindly help me by tell me if forget password is configured probably to send emails in the background and why do I get this error KeyError: 'processName'?

First of all there is a simple way of sending emails using celery:

django-celery-email

Second, your task is wrong. Task is a background job, not view. It should perform the final operation. In your case this is sending email
