Django is one of the most powerful web frameworks, but even experienced developers sometimes fall into rookie traps that can make their apps slow, insecure, or hard to maintain.

If you want to level up your Django skills and avoid common pitfalls, here are six mistakes that can expose you as a beginner — and how to fix them!

1. Using .all() Everywhere Without Filtering

The Mistake

Many beginners blindly use .all() in queries, leading to unnecessary database load.

Django Developers, Stop Using .all() for Queries – Here’s Why!

products = Product.objects.all()

This loads all products into memory — even if you only need one or two!

The Fix

Always filter your queries to fetch only what you need:

products = Product.objects.filter(category="Electronics")

Use .only() or .values() for better efficiency:

products = Product.objects.only("name", "price")
