Celery and Django simple example

Assuming you have both Python's celery and django-celery installed, create the following tasks.py file under your app:

utils/tasks.py

from celery import task# other imports@task()def create_user(data):    user = User.objects.create_user(        username=data['username'], email=None, password=data['password']    )    user.save()    profile = UserProfile()    profile.user = user    profile.token = generate_token()    profile.save()    return None

Delete your utils/utilities.py file in your example above.

In your code in views.py change the create_user call from:

create_user(form.cleaned_data)

to:

create_user.delay(form.cleaned_data)

Basically create_user is now a celery task; if you have the right Python packages installed (as mentioned above), code-wise (the implementation you ask for) that's it. delay executes your function asynchronously - i.e. the HTTP response is returned without waiting for the asynchronous task to complete.

Locally you can run a celery daemon process using python manage.py celeryd.

In production you have to set up the celery process itself using for instance upstart, supervisor or any other tool to control the lifecycle of such process.
