#Django tip 💚 if you use UUID7 for primary keys, why not use it for date range filters? It's really efficient 🔥 #tip

Q(uuid__gte=UUID7(shift=Value(start_datetime) - Now()))
Q(uuid__lte=UUID7(shift=Value(end_datetime) - Now()))

I had a heart 🫀surgery 2.5 weeks ago. Today I ran 🏃 for the first time since then, nothing long or fast (6.37 miles, pace 8:36 per mile ⏱️), but I did it! 🦵🥳 I can run again 🔥 #running #recovering #Indestructible

Django 6.1a1 is out 🎉 💚 I'm really happy and proud that database-level delete options for ForeignKey.on_delete (which we implemented during Django on the Med 🏖️ ) are one of the highlights of this release 💪 🤝 #django #djangoonthemed #sprint #python

This could be a game changer for anyone using model custom QuerySets and Managers 🎉 I've just implemented an 11 years old ticket 🧓 for initial filters on model QuerySets handled in such an elegant way 💎

objects = QuerySet.filter(active=True).as_manager()
