Handles sending notifications when a django-user-tasks completes.
|
|
This is a signal receiver for user_task_stopped. Currently it only sends
|
|
a generic "task completed" email, and only when a top-level task
|
|
completes. Eventually it might make more sense to create specific per-task
|
|
handlers.

Arguments:
|
|
sender (obj): Currently the UserTaskStatus object class

**kwargs: See below

Keywork Arguments:

|
status (obj): UserTaskStatus of the completed task

None
