Celery tasks for the CRATE consent-to-contact system.

See also crate_anon.crateweb.consent.celery, which defines the app.

If you get a “received unregistered task” error:

  1. Restart the Celery worker. That may fix it.

  2. If that fails, consider: SPECIFY ABSOLUTE NAMES FOR TASKS. e.g. with @shared_task(name="myfuncname"). Possible otherwise that if this module is imported in different ways (e.g. absolute, relative), you’ll get a “Received unregistered task” error. https://docs.celeryq.org/en/latest/userguide/tasks.html#task-names

Acknowledgement/not doing things more than once:
