Versions:

ipython==7.18.1
Django==3.0.5
python==3.8

If I run the following code using regular non-ipython django shell:

[x.scheduled_date for x in MyModel.objects.all()]

All is well and I see the list of scheduled dates. If I do the same using ipython, I get:

SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async.

I can run the following without error in both environments:

for x in MyModel.objects.all():
    print(x.scheduled_date)
