Understanding Django Project Structure: A Comprehensive Guide
Written on
Chapter 1: Introduction to Django Project Structure
In this section, we will delve into the organization of files and folders within a Django project, enhancing our understanding of their roles. The example project, named "first_app," was created using Django's command-line tools.
To view the project in Visual Studio Code, navigate to the project directory and enter the following command:
cmd
code .
This command will open the entire folder in VS Code.
Section 1.1: Key Files and Folders in a Django Project
The following describes the essential components of a Django project's file and folder structure:
db.sqlite3: This is the default database that Django uses.
manage.py: This vital file is the main entry point for running the project and handling migrations. If this file is absent or malfunctioning, the project will fail to run.
Templates Folder: This directory is designated for all HTML files related to the project. It's important to note that this folder doesn't exist by default, so it must be manually created in the project directory.
Static Folder: This folder contains all static resources such as JavaScript files, CSS stylesheets, images, and fonts. Similar to the templates folder, it must also be created manually.
Media Folder: This is utilized for storing dynamic images and files used throughout the project, and it too should be created in the project directory.
App Folder: Upon project creation, Django generates an App folder sharing the project's name. This folder contains crucial files such as settings.py, wsgi.py, and asgi.py.
URLs File: This file is essential for mapping URLs to the respective views.
Settings.py File: This file is pivotal as it manages various components of the project.
Section 1.2: Exploring the Settings.py File
Let’s take a closer look at the settings.py file, which plays a crucial role in project management. Here are some key elements:
- The path library is imported to obtain the working directory's path.
- A secret key is generated by default for use in the project.
- The DEBUG option is set to true, enabling error reporting during development.
- The ALLOWED_HOSTS setting allows you to specify the host or multiple hosts in list form, accommodating local hosts or custom ports.
- INSTALLED_APPS keeps track of default and migrated tables.
- MIDDLEWARE is implemented to restrict user access to the admin panel, ensuring that data is only visible after logging in.
- The TEMPLATES setting connects the templates folder to the base directory.
- The DATABASE section defines the database name and engine.
- The STATIC_URL setting specifies the path to the static folder, which is referenced when running the manage.py file.
