Getting Started with Django: A Practical Q&A Guide

Django is a mature Python web framework that has been around for over 15 years. Many developers appreciate its "batteries-included" philosophy and emphasis on explicitness over magic. This Q&A covers insights from someone who recently began using Django after trying other frameworks like Rails. It highlights how Django's design makes projects easier to maintain after long breaks, its powerful built-in admin interface, and the pleasant experience of its ORM. Whether you're considering Django for a new project or just curious about its strengths, these questions will help you understand its core appeal.

1. What makes Django feel less “magical” than Rails?

One of the first things you notice when switching from Rails to Django is how explicit everything feels. In Rails, conventions like resources :topics in routes.rb automatically create many routes, but if you haven't touched the project in months, you may struggle to remember where those routes are configured. You have to recall Rails conventions or look them up. Django, by contrast, relies on clear, direct references. Your URL patterns are defined in urls.py with explicit mappings to view functions. Templates are usually referenced directly from views. This transparency means that when you come back to a Django project after a long hiatus, you can quickly trace how a request flows through the application without needing to memorize hidden rules. The framework doesn't hide complexity behind implicit naming; it puts the structure right in front of you, which is a huge advantage for developers who maintain multiple projects over time.

2. How does Django's built-in admin work and how customizable is it?

Django comes with a fully functional admin interface that automatically generates CRUD pages for your models. You can activate it by adding a few lines to admin.py and registering your models. The admin is not a one-size-fits-all tool; you can customize it with a small amount of code. For example, you can define a ModelAdmin class to control which fields appear in list views, enable search, set default ordering, and mark fields as read-only. In the original text, the author shows how they configured the Zine model admin to display name, publication_date, free, slug, and image_preview in the list view, search by name and slug, and order by publication date descending. Customization can go much further—adding filters, inline editing, custom actions, and widgets. This built-in admin saves immense development time, especially for internal tools or quick content management, and it's one of Django's most loved features.

3. What makes Django's ORM enjoyable to use?

Many developers who prefer writing raw SQL are often skeptical of ORMs. However, Django's ORM is designed to be intuitive and powerful without sacrificing clarity. One particularly elegant feature is the use of double underscores (__) to traverse relationships. For instance, Zine.objects.exclude(product__order__email_hash=email_hash) generates a query that joins five tables—zines, zine_products, products, order_products, and orders—all through a ManyToManyField relationship. You simply tell Django about the relationships in your models, and it handles the joins automatically. This reduces boilerplate and keeps your code readable. The ORM also provides filtering, aggregation, annotations, and lazy evaluation, which means queries are executed only when you actually access the data. For complex projects, the ORM helps maintain clean separation between business logic and database access, while still allowing you to drop into raw SQL when needed.

4. Why is Django particularly suitable for projects you leave untouched for months?

Many side projects are developed in bursts, with months or even years between active periods. Django's explicitness makes it easy to pick up where you left off. The author points out that in a small Django project, the core structure is spread across just five main files: urls.py, models.py, views.py, admin.py, and tests.py. All other resources (like HTML templates) are explicitly referenced from these files. There's no magic that requires you to remember hidden conventions. Additionally, Django's documentation is excellent and the framework is stable—your old code will likely still work with minimal changes. The built-in admin also helps you quickly inspect the database state without writing queries. Combined with the ORM's intuitive interface, Django reduces the cognitive load of resuming a dormant project.

5. How does Django's explicit configuration improve maintainability?

In Django, almost everything is explicitly configured rather than inferred by convention. For example, if you want to add a new URL route, you write a line in urls.py that maps a pattern to a view function. If you want to customize the admin, you define a ModelAdmin class. This is in stark contrast to Rails, where conventions can make it unclear where certain behaviors originate. When you revisit a Django project, you can open urls.py and immediately see all routes. The same goes for templates—they are referenced directly in views or via the generic class-based views. This explicitness means less guesswork and faster onboarding, even for yourself months later. It also makes collaboration easier, as new team members can understand the codebase without extensive knowledge of hidden defaults.

6. What is the typical file structure of a simple Django project?

A basic Django project, after running django-admin startproject and python manage.py startapp, consists of several key files. The main project folder contains settings.py (configuration), urls.py (root URL configuration), and wsgi.py/asgi.py (deployment entry points). Inside each app, you'll find models.py (database schema), views.py (business logic), urls.py (app-specific routes, often included from the root), admin.py (admin interface customization), and tests.py (unit tests). Templates are stored in a templates directory, usually referenced explicitly from views. This flat, explicit structure means you can quickly navigate any Django project. The author emphasizes that having only a handful of main files (aside from settings) makes it easy to locate where everything is defined, which is especially valuable for infrequently touched projects.
