Use Django's bulk_create() for batch inserts instead of loops:
Model.objects.bulk_create([Model(name="A"), Model(name="B")])
Way faster than calling .save() in a loop!

Your cat doesn't rub against you because they love you. They’re actually marking you with their scent. Congratulations, you’re now property.

Django’s values_list() is great for fetching only what you need.
emails = User.objects.values_list("email", flat=True). This fetches just the email field instead of entire objects → faster & memory efficient!

Set blank=True vs null=True in models carefully.
🔹 blank=True → field can be empty in forms
🔹 null=True → stores NULL in DB
Use null=True only for non-text fields!

Scientists have found that cats can make over 100 different sounds. Unfortunately, almost all of them mean 'feed me.'

Does anyone know if cats can lose their sense of smell? I swear Eddie can only find food by sight or sound. You can open cheese and he seems to have no idea until he sees it, and then he's all over it

According to the internet, a cat's tail can express a wide range of emotions, from happiness to fear. But I swear Eddie's only expresses "I love you" or "I'm going to bite you, no matter where you move to" #cats
