Plugin JobRunner failing to see new object

[callieglade]

I'm writing a reservation plugin so that when an object is created, the save() function creates a background job which changes the object's status from Active to Inactive at the reservation's end date. I've written my jobs based on this doc, and it creates the job, but immediately errors out with AttributeError("'NoneType' object has no attribute 'status'"). It seems the reservation object isn't being passed correctly to the job, but i'm not sure how to fix this or what's wrong in my code. I'm on v4.2.6.

Here's a snippet of relevant information from my models.py:

...
from netbox.models import NetBoxModel
from netbox.models.features import JobsMixin
from utilities.choices import ChoiceSet

from .validators import ReservationValidator
from .jobs import PlannedToActiveJob, ActiveToInactiveJob
...
def save(self, *args, **kwargs):
        # create PlannedToActiveJob if job status is planned
        if self.status == StatusChoices.STATUS_PLANNED:
            PlannedToActiveJob.enqueue_once(instance=self, scheduled_at=self.start_date, status_choices=StatusChoices)
        # ActiveToInactiveJob is always created
        ActiveToInactiveJob.enqueue_once(instance=self, scheduled_at=self.end_date, status_choices=StatusChoices)
        return super().save(*args, **kwargs)

and here's a snippet from my jobs.py:

from django.core.exceptions import ValidationError
from netbox.jobs import JobRunner

class PlannedToActiveJob(JobRunner):
  class Meta:
    name = "Status Updater: Planned to Active"

  def run(self, status_choices, *args, **kwargs):
    obj = self.job.object

    if obj.status == status_choices.STATUS_PLANNED:
      obj.status = status_choices.STATUS_ACTIVE
    else:
      raise ValidationError(_("Status provided is not valid for scheduled Planed to Active update! Received: %(status)s"), params={"status": obj.status})
    
class ActiveToInactiveJob(JobRunner):
  class Meta:
    name = "Status Updater: Active to Inactive"

  def run(self, status_choices, *args, **kwargs):
    obj = self.job.object

    if obj.status == status_choices.STATUS_ACTIVE:
      obj.status = status_choices.STATUS_INACTIVE
    else:
      raise ValidationError(_("Status provided is not valid for scheduled Active to Inactive update! Received: %(status)s"), params={"status": obj.status})

Here are the logs I see from netbox-worker for the creation (and subsequent erroring out) of this job:

2025-04-07 12:17:43 19:17:43 default: handle(job=<Job: 212698ba-7e2b-4b3c-aa64-ed7904bc988b>, scheduled_at=datetime.datetime(2025, 4, 12, 7, 0, tzinfo=zoneinfo.ZoneInfo(key='UTC')), status_choices=<class 'netbox_reservations_plugin.models.StatusChoices'>) (212698ba-7e2b-4b3c-aa64-ed7904bc988b)
2025-04-07 12:17:43 19:17:43 Successfully completed handle(job=<Job: 212698ba-7e2b-4b3c-aa64-ed7904bc988b>, scheduled_at=datetime.datetime(2025, 4, 12, 7, 0, tzinfo=zoneinfo.ZoneInfo(key='UTC')), status_choices=<class 'netbox_reservations_plugin.models.StatusChoices'>) job in 0:00:00.084867s on worker 130cee2fbbbf42e0a66c30d9b6b14c47

the status choices from the model, and the scheduled_at time, are accurately passed to handle(), and the correct object_type is also there. If I were to guess based on all of this, it seems like the issue has to do with the object not existing yet at the time that enqueue() is called. However, if this is the case, I don't know how to work around this such that the job is created on object creation. Possibly a post_save signal, but I don't want to dive into that rabbit hole until I'm more confident that I should go that direction.
