Setting up the right Django project working directory structure is crucial for maintainability, scalability, and overall project health. A well-organized structure makes it easier for developers to navigate the codebase, collaborate effectively, and deploy the application seamlessly. Neglecting this aspect can lead to a tangled mess of files, making debugging and future development a nightmare. This comprehensive guide explores best practices for organizing your Django projects, covering everything from the initial project setup to advanced techniques for managing complex applications. We’ll delve into the benefits of a standardized structure and provide actionable steps to implement these practices in your own projects, ensuring long-term success and reduced technical debt.

Understanding the Importance of a Good Project Structure

A coherent Django project working directory structure is the foundation of any successful Django application. Think of it as the architectural blueprint for your software – the better the blueprint, the stronger and more resilient the building. A poorly structured project often suffers from code duplication, circular dependencies, and a general lack of clarity, leading to increased development time and higher maintenance costs. According to a study by the Consortium for Information & Software Quality (CISQ), poor architectural design contributes to a significant percentage of project failures [¹].

Conversely, a well-defined structure promotes modularity, making it easier to isolate and fix bugs. It also simplifies the process of adding new features or refactoring existing code. With a clear structure, developers can quickly understand the purpose of each file and directory, reducing the learning curve for new team members. Furthermore, a consistent structure across multiple projects allows developers to easily transfer their skills and knowledge between teams. By adopting established conventions, you create a predictable and understandable environment for everyone involved. This not only improves productivity but also contributes to a more enjoyable development experience. The benefits of a clean project structure extend beyond just the immediate development phase, impacting the entire lifecycle of the application.

Consider the example of a large e-commerce platform. Without a clear structure, managing models, views, templates, and static files would become incredibly difficult. A single change in one area could unintentionally break functionality in another. By organizing these elements logically and consistently, developers can minimize the risk of unintended consequences and ensure that the platform remains stable and reliable, as cited by the Django documentation [²]. This is why understanding and implementing a robust Django project working directory structure is paramount.

Recommended Project Layout and Conventions

The “startproject” command in Django provides a basic project structure, but it’s often insufficient for more complex applications. Best practices dictate a more organized layout that separates concerns and promotes modularity. One common approach is to keep the core project settings and management scripts in a dedicated directory, separate from the individual app directories. This makes it easier to manage project-wide configurations and utilities. Here’s a recommended structure:

myproject/: The outer container directory.
config/: Contains project-level settings and URL configurations.
manage.py: Django’s management script.
apps/: A directory to house all your Django apps.
static/: For project-level static files (CSS, JavaScript, images).
templates/: For project-level templates.

Inside the config/ directory, you would typically find files like settings.py (or separate settings files for different environments), urls.py (the root URL configuration), wsgi.py (for WSGI deployment), and asgi.py (for ASGI deployment). The apps/ directory then contains individual Django apps, each responsible for a specific part of the application’s functionality. For example, you might have apps for “users,” “products,” “orders,” and so on. Keeping your apps separate makes them more reusable and easier to maintain. Django’s official documentation provides detailed guidance on structuring apps [³].

This structure improves code organization. Each app lives in its own directory, with its own models, views, and templates. This modular approach makes it easier to understand the project’s architecture. It also allows different teams to work on separate parts of the application without interfering with each other. Furthermore, this structure promotes code reuse. If you need similar functionality in another project, you can easily copy and paste an entire app without having to worry about dependencies or conflicts. Proper use of a Django project working directory structure facilitates efficient code management.

Structuring Your Apps for Scalability and Maintainability

Within each Django app, it’s equally important to follow a consistent structure. This involves organizing your models, views, forms, and templates in a logical manner. A common practice is to create separate modules for different types of views, such as API views, form views, and template views. This makes it easier to find and modify the code responsible for handling different types of requests.

Here’s a typical structure for a Django app:

myapp/: The app’s root directory.
models.py: Defines the data models.
views.py: Contains the view functions or classes.
forms.py: Defines the forms used in the app.
urls.py: Specifies the URL patterns for the app.
templates/: Stores the HTML templates.
static/: Contains static files specific to the app.
admin.py: Registers models with the Django admin interface.
tests.py: Contains unit tests for the app.

For larger apps, consider further breaking down the views.py file into multiple modules, such as views/api.py, views/forms.py, and views/templates.py. Similarly, you can organize your templates into subdirectories based on functionality. For example, you might have a templates/myapp/users/ directory for user-related templates and a templates/myapp/products/ directory for product-related templates. This level of organization makes it much easier to navigate the codebase and find the specific files you need. Effective Django project working directory structure includes well-organized apps.

To improve scalability, consider using class-based views. Class-based views offer a more structured and reusable way to define views. They allow you to easily inherit from existing views and override specific methods to customize their behavior. This can significantly reduce code duplication and make your views more maintainable. You can also use mixins to add common functionality to multiple views. Mixins are reusable classes that provide specific functionality, such as authentication or permission checking. By using class-based views and mixins, you can create a more modular and scalable architecture for your Django apps. Class-based views are a powerful tool for building complex applications, while ensuring a clear Django project working directory structure.

Advanced Techniques and Best Practices

Beyond the basic project layout, there are several advanced techniques that can further enhance your Django project working directory structure and improve its overall quality. One such technique is the use of environment variables for managing sensitive information and configuration settings. Instead of hardcoding passwords, API keys, and other sensitive data directly into your settings files, you can store them as environment variables and access them using a library like python-decouple.

Here’s how you can use environment variables in your Django project:

Install the python-decouple library: pip install python-decouple.
Define your environment variables in a .env file.
Access the environment variables in your settings.py file using the config object.

Another best practice is to use a virtual environment for each Django project. A virtual environment creates an isolated Python environment for your project, preventing conflicts between different projects and ensuring that your project’s dependencies are managed correctly. You can create a virtual environment using the venv module in Python. To optimize your project, utilize .gitignore files to exclude unnecessary files and directories from version control, like virtual environment directories or compiled Python files (.pyc), further streamlining your Django project working directory structure.

Consider using a package like Django Cookiecutter to bootstrap your projects. It will help set up the core structure for your project and ensure you follow industry best practices from the beginning. By automating the project setup process, you can focus on writing code and building features, rather than spending time on tedious configuration tasks. Cookiecutter is a powerful tool for creating consistent and well-structured Django projects. It promotes code reuse and helps you avoid common pitfalls. The best Django project working directory structure often begins with a solid foundation.

I know there is actually no single right way. However I've found that it's hard to create a directory structure that works well and remain clean for every developer and administrator. There is some standard structure in most projects on github. But it does not show a way to organize another files and all projects on pc.

What is the most convenient way to organize all these directories on development machine? How do you name them, and how do you connect and deploy this to server?

projects (all projects that your are working on)
source files (the application itself)
working copy of repository (I use git)
virtual environment (I prefer to place this near the project)
static root (for compiled static files)
media root (for uploaded media files)
README
LICENSE
documents
sketches
examples (an example project that uses the application provided by this project)
database (in case sqlite is used)
anything else that you usually need for successful work on project

The problems that I want to solve:

Good names of directories so that their purpose is clear.
Keeping all project files (including virtualenv) in one place, so I can easily copy, move, archive, remove whole project or estimate disk space usage.
Creating multiple copies of some selected file sets such as entire application, repository or virtualenv, while keeping single copy of another files that I don’t want to clone.
Deploying right set of files to the server simply by rsyncing selected one dir.

There’re two kind of Django “projects” that I have in my ~/projects/ directory, both have a bit different structure.:

Stand-alone websites
Pluggable applications

Stand-alone website

Mostly private projects, but doesn’t have to be. It usually looks like this:

~/projects/project_name/ docs/ # documentation scripts/ manage.py # installed to PATH via setup.py project_name/ # project dir (the one which django-admin.py creates) apps/ # project-specific applications accounts/ # most frequent app, with custom user model __init__.py ... settings/ # settings for different environments, see below __init__.py production.py development.py ... __init__.py # contains project version urls.py wsgi.py static/ # site-specific static files templates/ # site-specific templates tests/ # site-specific tests (mostly in-browser ones) tmp/ # excluded from git setup.py requirements.txt requirements_dev.txt pytest.ini ...

Settings

The main settings are production ones. Other files (eg. staging.py, development.py) simply import everything from production.py and override only necessary variables.

For each environment, there are separate settings files, eg. production, development. I some projects I have also testing (for test runner), staging (as a check before final deploy) and heroku (for deploying to heroku) settings.

Requirements

I rather specify requirements in setup.py directly. Only those required for development/test environment I have in requirements_dev.txt.

Some services (eg. heroku) requires to have requirements.txt in root directory.

`setup.py`

Useful when deploying project using setuptools. It adds manage.py to PATH, so I can run manage.py directly (anywhere).

Project-specific apps

I used to put these apps into project_name/apps/ directory and import them using relative imports.

Templates/static/locale/tests files

I put these templates and static files into global templates/static directory, not inside each app. These files are usually edited by people, who doesn’t care about project code structure or python at all. If you are full-stack developer working alone or in a small team, you can create per-app templates/static directory. It’s really just a matter of taste.

The same applies for locale, although sometimes it’s convenient to create separate locale directory.

Tests are usually better to place inside each app, but usually there is many integration/functional tests which tests more apps working together, so global tests directory does make sense.

Tmp directory

There is temporary directory in project root, excluded from VCS. It’s used to store media/static files and sqlite database during development. Everything in tmp could be deleted anytime without any problems.

Virtualenv

I prefer virtualenvwrapper and place all venvs into ~/.venvs directory, but you could place it inside tmp/ to keep it together.

Project template

I’ve created project template for this setup, django-start-template

Deployment

Deployment of this project is following:

source $VENV/bin/activate export DJANGO_SETTINGS_MODULE=project_name.settings.production git pull pip install -r requirements.txt # Update database, static files, locales manage.py syncdb --noinput manage.py migrate manage.py collectstatic --noinput manage.py makemessages -a manage.py compilemessages # restart wsgi touch project_name/wsgi.py

You can use rsync instead of git, but still you need to run batch of commands to update your environment.

Recently, I made django-deploy app, which allows me to run single management command to update environment, but I’ve used it for one project only and I’m still experimenting with it.

Sketches and drafts

Draft of templates I place inside global templates/ directory. I guess one can create folder sketches/ in project root, but haven’t used it yet.

Pluggable application

These apps are usually prepared to publish as open-source. I’ve taken example below from django-forme

~/projects/django-app/ docs/ app/ tests/ example_project/ LICENCE MANIFEST.in README.md setup.py pytest.ini tox.ini .travis.yml ...

Name of directories is clear (I hope). I put test files outside app directory, but it really doesn’t matter. It is important to provide README and setup.py, so package is easily installed through pip.
