Python Django Rest Framework UnorderedObjectListWarning
So in order to fix this I had to find all of the all
, offset
, filter
, and limit
clauses and add a order_by
clause to them. Some I fixed by adding a default ordering:
class Meta: ordering = ['-id']
In the ViewSets for Django Rest Framework (app/apiviews.py) I had to update all of the get_queryset
methods as adding a default ordering didn't seem to work.
Hope this helps someone else. :)
I was getting this warning when i used objects.all() in my view.py
profile_list = Profile.objects.all()paginator = Paginator(profile_list, 25)
to fix this i changed my code to :
profile_list = Profile.objects.get_queryset().order_by('id')paginator = Paginator(profile_list, 25)
Let me give an answer updated to new developments...

The default ordering of the User
model has been removed in Django. If you found yourself at this page because of an upgrade, it's very likely connected to this change.
There are 2 versions of this problem you might be dealing with.
- your own model does not have a default ordering in its
Meta
(see accepted answer) - you are using a model from an app you are using as a dependency which does not have a default ordering
Since literally the Django User
model itself does not adhere to ordering, it's very clear that the second scenario cannot be resolved by asking the maintainers of those dependencies to put in a default ordering. Okay, so now you either have to override the model being used for whatever your doing (sometimes a good idea, but not good for addressing such a minor issue).
So you're left with addressing it on the view level. You also want to do something that will play nicely with any ordering filter class you have applied. For that, set the view's ordering
parameter.
class Reviewers(ListView): model = User paginate_by = 50 ordering = ['username']
