How to Easily Override and Extend Django Admin Templates?

How to Override and Extend Django Admin Templates with Ease

When working with Django, it's common to encounter the need to customize admin templates while still maintaining their original functionality. This can be achieved through a combination of overriding and extending the templates.

However, the traditional approach of extending admin templates directly can become cumbersome when using the app_directories template loader. To address this, a custom template loader has been developed to simplify the process.

This template loader allows you to extend templates in specific apps, such as the admin app. This gives you the flexibility to create customized versions of templates like admin/index.html, which extend the originals.

Example Customization

To illustrate the process, let's say we want to add extra links to the admin sidebar. We can extend the admin/index.html template as follows:

{% extends "admin:admin/index.html" %}

{% block sidebar %}
    {{ block.super }}
    <div>
        <h1>Extra Links</h1>
        <a href="/admin/extra/">My Extra Link</a>
    </div>
{% endblock %}

In this example, we extend the original sidebar block and add our custom content while preserving the original functionality.

Conclusion

By leveraging this custom template loader, you can easily override and extend Django admin templates, enabling you to customize the admin interface without disrupting its base functionality.
