Introduction to Static Files
In Django, static files are files like CSS, JavaScript, and images that are not generated dynamically by the server. They remain the same for every user and are essential for styling your web pages and adding interactivity. Think of them as the accessories that make your website look and feel great! 🎨
Key Terminology
- Static Files: Non-dynamic files such as CSS, JavaScript, and images.
- STATIC_URL: The URL prefix for static files.
- STATICFILES_DIRS: A list of directories where Django will search for additional static files.
- STATIC_ROOT: The directory where static files are collected for production.
Getting Started with Static Files
The Simplest Example
Let’s start with a basic example of setting up static files in a Django project.
django-admin startproject myproject
cd myproject
mkdir static
Here, we create a new Django project and a static directory to store our static files.
# settings.py
STATIC_URL = '/static/'
STATICFILES_DIRS = [
BASE_DIR / 'static',
]In your settings.py, set the STATIC_URL and add STATICFILES_DIRS to include the static directory.
Expected Output
When you run your Django server, static files will be served from the /static/ URL.
Progressively Complex Examples
Example 1: Adding CSS to Your Project
<!-- base.html -->
<link rel="stylesheet" type="text/css" href="{% static 'styles.css' %}">Use the {% static %} template tag to link to your CSS file in your HTML templates.
/* static/styles.css */
body {
background-color: #f0f0f0;
}Expected Output
Your web page will have a light gray background.
Example 2: Serving Static Files in Production
# settings.py
STATIC_ROOT = BASE_DIR / 'staticfiles'Set STATIC_ROOT to specify the directory where static files will be collected for production.
python manage.py collectstaticRun collectstatic to gather all static files into the STATIC_ROOT directory.
Example 3: Using Multiple Static Directories
# settings.py
STATICFILES_DIRS = [
BASE_DIR / 'static',
'/var/www/static/',
]You can specify multiple directories for Django to search for static files.
