I upgraded from Django 1.10.4 to 1.11.1 and all of a sudden I"m getting a ton of these messages when I run my tests:
lib/python3.5/site-packages/rest_framework/pagination.py:208:
UnorderedObjectListWarning:
Pagination may yield inconsistent results with an unordered object_list:
<QuerySet [<Group: Requester>]>
paginator = self.django_paginator_class(queryset, page_size)
I"ve traced that back to the Django Pagination module: https://github.com/django/django/blob/master/django/core/paginator.py#L100
It seems to be related to my queryset code:
return get_user_model().objects.filter(id=self.request.user.id)
How can I find more details on this warning? It seems to be that I need to add a order_by(id)
on the end of every filter, but I can"t seem to find which code needs the order_by added (because the warning doesn"t return a stack trace and so it happens randomly during my test run).
Thanks!
Edit:
So by using @KlausD. verbosity tip, I looked at a test causing this error:
response = self.client.get("/api/orders/")
This goes to OrderViewSet
but none of the things in get_queryset cause it and nothing in serializer class causes it. I have other tests that use the same code to get /api/orders and those don"t cause it.... What does DRF do after get_queryset?
https://github.com/encode/django-rest-framework/blob/master/rest_framework/pagination.py#L166
If I put a traceback into pagination then I get a whole bunch of stuff related to django rest framework but nothing that points back to which of my queries is triggering the order warning.

Python Django Rest Framework UnorderedObjectListWarning __del__: Questions
How can I make a time delay in Python?
5 answers
I would like to know how to put a time delay in a Python script.
Answer #1
import time
time.sleep(5) # Delays for 5 seconds. You can also use a float value.
Here is another example where something is run approximately once a minute:
import time
while True:
print("This prints once a minute.")
time.sleep(60) # Delay for 1 minute (60 seconds).
Answer #2
You can use the sleep()
function in the time
module. It can take a float argument for sub-second resolution.
from time import sleep
sleep(0.1) # Time in seconds

__del__ is always a bit confusing 😭 Python Django Rest Framework UnorderedObjectListWarning is not the only problem I encountered. Will use it in my bachelor thesis

I was preparing for my coding interview, thanks for clarifying this - Python Django Rest Framework UnorderedObjectListWarning in Python is not the simplest one. Will use it in my bachelor thesis
