Solving 404 for Static Files with Django and Nginx

Ubuntu 18

In this article, we will tackle a common issue faced by developers when deploying Django applications with Nginx – the notorious 404 error for static files. This error typically occurs when the server is unable to locate the static files for your application. We’ll go through the steps to solve this issue, ensuring your static files are correctly served.

Quick Answer

To solve the 404 error for static files with Django and Nginx, you need to ensure your Django settings are correctly configured with the STATIC_URL and STATIC_ROOT settings. Then, use the collectstatic command to gather all static files into the STATIC_ROOT directory. Finally, configure Nginx to serve these static files by adding a location block to the Nginx configuration file. Restart Nginx and test your setup to ensure the static files are served correctly.

Understanding Django Static Files

Before we delve into the solution, it’s important to understand what static files are. In Django, static files refer to files that are not dynamically generated. They include CSS files, JavaScript files, and images. These files are typically stored in a directory named static in each Django application.

In Django, two settings are responsible for handling static files – STATIC_URL and STATIC_ROOT.

  • STATIC_URL is the URL to use when referring to static files. It’s typically set to /static/.
  • STATIC_ROOT is the absolute path to the directory where collectstatic will gather static files for deployment.

Configuring Django Settings

Let’s start by ensuring your Django settings are correctly configured.

  1. Open your settings.py file.
  2. Check the STATIC_URL and STATIC_ROOT settings. STATIC_URL should be set to /static/, and STATIC_ROOT should be set to the absolute path where you want your static files to be collected.

Here’s an example:

STATIC_URL = '/static/'
STATIC_ROOT = '/var/www/mywebsite/static/'

Collecting Static Files

Once your settings are correctly configured, you need to collect all static files into the STATIC_ROOT directory. Django provides a command for this: python manage.py collectstatic.

This command looks for static files in each of your applications (and any other places specified by the STATICFILES_DIRS setting) and copies them to the directory specified by STATIC_ROOT.

Configuring Nginx to Serve Static Files

After collecting static files, you need to configure Nginx to serve these files. This is done by adding a location block to the Nginx configuration file.

  1. Open your Nginx configuration file. This is usually located at /etc/nginx/nginx.conf or /etc/nginx/sites-available/default.
  2. Inside the server block, add the following location block:
location /static/ {
 alias /var/www/mywebsite/static/;
}

In this block, alias specifies the file system path to the static files, which should match the STATIC_ROOT setting in your Django configuration.

  1. Save the configuration file and restart Nginx to apply the changes. The command to restart Nginx typically is sudo systemctl restart nginx.

Testing and Troubleshooting

Finally, test your setup by accessing your Django application. If everything is configured correctly, your static files should be served without any issues.

If you still encounter 404 errors, check the Nginx error log for any messages. This is typically located at /var/log/nginx/error.log.

Remember, serving static files directly from Nginx is recommended for production environments due to its superior performance. Django can serve static files when the DEBUG setting is enabled, but this is not suitable for production.

Conclusion

Solving the 404 error for static files in Django when using Nginx involves correctly configuring your Django settings, collecting static files, and configuring Nginx to serve these files. By following the steps in this guide, you should be able to solve this issue and ensure your static files are served correctly.

For more information, you can refer to the Django documentation on static files and the Nginx documentation on serving static files.

What is the purpose of the `collectstatic` command in Django?

The collectstatic command in Django is used to collect all static files from your applications and any other specified directories into a single directory specified by the STATIC_ROOT setting. This is necessary for serving static files correctly in a production environment.

Can I change the name of the `static` directory in my Django application?

Yes, you can change the name of the static directory in your Django application. To do this, you need to update the STATIC_URL and STATIC_ROOT settings in your Django configuration to reflect the new directory name. Additionally, you may need to update the STATICFILES_DIRS setting if you have other directories where static files are stored.

How do I verify that Nginx is serving my static files correctly?

To verify that Nginx is serving your static files correctly, you can access your Django application in a web browser and inspect the page source. Look for the URLs of your static files (e.g., CSS, JavaScript, images) and ensure that they are being loaded from the correct location specified by the STATIC_URL and STATIC_ROOT settings in your Django configuration.

Can Django serve static files in a production environment without Nginx?

While Django can serve static files when the DEBUG setting is enabled, it is not recommended for production environments. Serving static files directly from Nginx is recommended for better performance and security. Django’s built-in static file serving is primarily intended for development and testing purposes.
