In a detailed walkthrough, the author explains how to create a simple Django application that supports bulk downloading of code snippets as zip files. The process involves setting up a virtual environment, installing Django, creating a Django project and app, and configuring the necessary routes and models. The app utilizes Django's ORM to store and retrieve code snippets, which are then packaged into a zip file using Python's zipfile module and served through a download endpoint. The author also highlights how to integrate this feature with Django's admin interface for ease of management and suggests enhancing security by restricting access to authenticated users. The full implementation details and code are made available in a blog code repository for further exploration and use.
