Pulp

A use case for pulp_ansible came up recently whereby tasks need to dispatch subtasks. It would be useful for them to see and filter on parent_task and child_tasks fields in the Task model.

Deliverables¶

1. parent_task and child_task fields added to the [Task model[(https://github.com/pulp/pulpcore/blob/b94abcea602712c7610595078a3d26a2029725e1/pulpcore/app/models/task.py#L310).
2. Having these viewable on the TaskSerializer
3. Having them filterable on TaskFilter
4. Have the enqueue_with_reservation method automatically set the 'parent/child' relationship.

Background¶

We used to have this, so we need to bring it back and add tests for it with this work. Here are some PRs to reference:

• This was what we had setting 'parent' but it's incomplete https://github.com/pulp/pulpcore/pull/569
• When we removed it from the serializers before: https://github.com/pulp/pulpcore/commit/3e3ea72ac2bf0abab82a642a987122660cabc124#diff-012d87c176cc670b2ae1f9b498f8b930
