How can I add Celery to an existing project?

[LucasLeone]

I'm doing a project without Celery, but I need it now. How can I add it?

I need add functionality for send confirmation email with this code:

@task(name='send_confirmation_email', max_retries=3)
def send_confirmation_email(user_pk):
    """Send account verification link to given user."""
    user = User.objects.get(pk=user_pk)
    verification_token = gen_verification_token(user)
    subject = 'Welcome @{}! Verify your account to start using project.format(user.username)
    from_email = 'project <[email protected]>'
    content = render_to_string(
        'emails/users/account_verification.html',
        {'token': verification_token, 'user': user}
    )
    msg = EmailMultiAlternatives(subject, content, from_email, [user.email])
    msg.attach_alternative(content, "text/html")
    msg.send()

Thanks!

I see a few options:

• Follow the guide from the official Celery docs
• Search through the template repo where use_celery is: https://github.com/search?q=repo%3Acookiecutter%2Fcookiecutter-django+use_celery+path%3A%2F%5E%5C%7B%5C%7Bcookiecutter%5C.project_slug%5C%7D%5C%7D%5C%2F%2F&type=code and make similar changes in your generated project
• Regenerate a new project from scratch and copy your code into it

There is currently (AKAIK) no official way of updating an existing project (#1047) nevermind changing the original options after generation.

As 3rd party/extension, there is cruft, which supports updating and claims to be fully compatible with cookiecutter.
