Показать описание
In this video, we'll show examples of how to perform Conditional Expressions in Django.

These allow developers to perform IF/ELSE logic within database queries, and get back values based on conditions that are defined using Case and When objects.

I will be deceiving myself if I don't drop a comment on this. These are advanced topics littered in few books. You have simplified everything.❤

I use to use Pandas for that type of data analysis but the orm seems like a robust way to handle the same logic, thank your good Sr.

Perfect. Simple, clear and well explained. Continue this way. I do not raise very often comment but as previously said by others, it is really great videos on ORM. Many thanks for your time and dedication. You should think about posting training on udemy or others sites, I will definitively support you.

THIS ... WAS ... AWESOME. I've yet to use the case and when structures so was. More advanced topics are welcome.

Here's an idea/challenge I was mulling over the other day in regards to Django vs FastApi. Everyone wants fast, modern and async, but I won't give up on the orm or the migrations. Yes I can use SQLAlchemy and Alembic, but it doesn't have the same sleekness.

Can you get the same speed and lightness in Django by using Daphne/Uvicorn ASGI, the async ORM functions, and async functions using Django-Nina as the serializer?

I'm not sure if ninja has implemented pydantic 2.0 yet, but their first full release is in beta 1.
