What is the difference between filter() and get()?

`filter()` always returns a QuerySet (a list-like object), even if it only finds 1 result. `get()` directly returns the single python object itself. However, `get()` will crash the app if it finds 0 results or 2+ results.

How do I count the total records?

Never use `len(User.objects.all())`. That pulls millions of records into RAM just to count them. Always use `User.objects.count()`, which fires a highly optimized `SELECT COUNT(*)` query at the database level.

Can I see the raw SQL Django generates?

Yes! If you print `print(my_queryset.query)`, Django will literally output the exact raw SQL string (e.g., `SELECT * FROM...`) that it is preparing to send to the database.
