How to specify GROUP BY field in Dajngo ORM?
I have the following working SQL statement: SELECT id FROM ops_kpitarget WHERE (site_id = 1 AND validFrom <= "2019-08-28") GROUP BY kpi_id HAVING validFrom = (MAX(validFrom)) But I cannot get this to work inside Django ORM. The best I got was the code below, but then the database is complaining that it is missing a GROUP BY clause to make HAVING work. How can I get the same query with specifying "kpi_id" as the GROUP BY clause using Djangos ORM? Any ideas? KpiTarget.objects .filter(validFrom__lte=fromDate) .values("id", "kpi") .filter(validFrom=Max("validFrom")) ... which translates to: SELECT "ops_kpitarget"."id", "ops_kpitarget"."kpi_id" FROM "ops_kpitarget" WHERE "ops_kpitarget"."validFrom" <= 2019-08-14 HAVING "ops_kpitarget"."validFrom" = (MAX("ops_kpitarget"."validFrom")) I played around with annotate but this is not really giving me what I want... -

Cannot Import name from myapp.models
I am using django 2.2.4 and python 3.7.3 When I try to import anything from forum.models into gallery/models.py , I get importError: cannot import name 'Project' from 'forum.models', but it works fine the other way around (importing from gallery.models into forum/models.py. ├── db.sqlite3 ├── forum │ ├── admin.py │ ├── apps.py │ ├── __init__.py │ ├── migrations │ ├── models.py │ ├── __pycache__ │ ├── tests.py │ └── views.py ├── gallery │ ├── admin.py │ ├── apps.py │ ├── __init__.py │ ├── migrations │ ├── models.py │ ├── __pycache__ │ ├── tests.py │ └── views.py ├── makerplatform │ ├── __init__.py │ ├── __pycache__ │ ├── settings.py │ ├── urls.py │ └── wsgi.py ├── manage.py With that said, I tried this in gallery/models.py: import forum.models as m print(m.__dir__()) and its when I run manage.py runserver: ['__name__', '__doc__', '__package__', '__loader__', '__spec__', '__file__', '__cached__', '__builtins__', 'models', 'User', 'post_save', 'receiver'] Notice that User,post_save, and receiver are all modules I imported into forum/models.py. I also tried importing forum.models in the django shell, and it works fine. Thanks in advance for any help.
