Comment (by Petr Boros):
Replying to [comment:5 Tim Graham]:
> I think the report is missing some detail to reproduce the issue
(perhaps some implementation detail of `PositionField`). For your case, it
looks like
[https://github.com/django/django/blob/89d4d412404d31ef34ae3170c0c056eff55b2a17/django/contrib/admin/checks.py#L658
hasattr(Trigger, 'position')] is failing which isn't the case for normal
model fields.
You are right, `hasattr(Trigger, 'position') == False`. However, at the
same time, `'position' in Trigger.__dict__.keys() == True`.
Why is that?
I am attaching the full source code of `PositionField` to this ticket for
reference. ''Note that the original source code comes from `django-
positions` package.''
