Hi Erik,
Thanks for the solution.
So, I understand we get all instances of B which are max (date created) or
latest (date created) for each instance of A and then we check b.text ==
'ABCD' and select the corresponding instance of A.
Can't we add additional filter to check if text='ABCD' inste
Thanks Erik. Will try out the solution you mentioned.

Hi Erik,
I tried your solution but there are some issues:
.filter(date_created=Max('a__b__date_created')) - this is throwing error

If I remove the above, the result isn't correct where when I go through

Hi Vjiay,
My apologies if the scenario is not clear. Following are the details:

relationships with other models). There are 10k records for A. Lets say
following is the pseudo code for the report:

Hi,
Is there a way to debug Django when DEBUG is set to False in settings.py
(for example on production)?
The reason for asking the above is if we face any issue with DEBUG set to
False and if we need to debug.
We are new to Django and we are building an ecommerce platform based on
Django.
when DEBUG=False. It took some time to figure this out. Had there
been a log or some mechanism, debugging would have been lot easier and
quicker.
