Django Auto Prefetching

Overview

Django Auto-Prefetching is an innovative tool that aims to enhance the performance of Django projects, especially those utilizing the Django REST framework. By automatically generating the necessary select_related and prefetch_related calls based on the fields and models specified in your serializers, it effectively eliminates common n+1 query problems that can hinder application efficiency. This project is particularly useful for developers looking to streamline their database queries without delving deep into the complexities of Django's ORM.

The integration process is straightforward, making it a viable option for both seasoned developers and those new to Django. With its clever handling of relational fields and ease of installation via pip, this tool enables developers to focus more on building features rather than optimizing performance manually.

Features
