You can define functions in ModelAdmin classes and use it in list_fields. Also, you can use annotate, values, Sum, Count and other functions to compute this "extra" data.
Thank you! I'll have a better look at the documents using some of the terms you've mentioned here.

Thank you! I'll have a better look at the documents using some of the terms you've mentioned here.
I'm googling for some examples, and I found this package:
https://pypi.org/project/django-admin-easy/
I never used it. But it may help.
Trev
It may be! What I'm hoping to accomplish is to:
1) Iterate through every entry in that model, if a boolean is True, count the numbers from a specific field
2) Add all of those numbers to _one count_ to be displayed in the admin page for that count
Trev
I.E: The number of people attending an event
Trev
I can probably get the data like:
query_set = Model.objects.all()
for person in query_set:
# Do stuff
It's the displaying of that data I'm not sure about.
Luis
Hmmm it's a complex stuff... give me a second to think a solution

I never do something like these, but I think proxy model can helps you.
Luis
Guys: any idea ?
Trev
Appreciate that, thank you!
Trev
Though I'm not sure a proxy model would be necessary. It's just a simple operation. It's not hard to query the required data. Maybe I can hack the number into the filter list or something
Trev
Then a user could click on the model, see the list of attendees and on the right, see the total number of people signed up, etc.

OK, if you can get the data from DB only create a function and use its name as a field.

Mirco
Can you explain briefly
Instead of hardcoding your success url, use reverse(), so you decrease the chances of typo errors
Krishna Praneeth
okk.Thank You😁😁
Krishna Praneeth
when i am using reverse i am getting circular import error
Anonymous
Helloo..
Anonymous
I have one doubt
Krishna Praneeth
yeah i will show you
Krishna Praneeth
django.core.exceptions.ImproperlyConfigured: The included URLconf 'tweetme.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.
