I'm trying to make a library compatible with both django 1.11 and 2.0b1,
but I've hit something of a snag.
I have added `manager_inheritance_from_future` to the `Meta` class of my
base model, which removes the following warning:
RemovedInDjango20Warning: Managers from concrete parents will soon
qualify as default managers if they appear before any other managers in
the MRO. ...you can switch to the new behavior right away by setting
`Meta.manager_inheritance_from_future` to `True`.
So far so good,uUnfortunately, now that I've added that for django 1.11,
I'm getting this error on django 2.0b1:
TypeError: 'class Meta' got invalid attribute(s):
manager_inheritance_from_future
The `manager_inheritance_from_future` option was removed in
631f4ab06112aca5bd6a57b81159048f936050bf, but this is pretty frustrating.
I'm not sure how to make this library compatible with both versions, as a
result of this.
Perhaps this removal was premature?
