Understand how Django's template engine resolves admin templates through a three-tier fallback system, allowing safe and precise customization. Learn to extend base templates, configure project paths correctly, and troubleshoot common override issues to redesign the admin interface confidently.
Before we write custom HTML to redesign the administration interface, we must understand how Django searches for its template files. If we place a file in the wrong directory, Django will silently ignore it and continue rendering the default interface.
By mastering the template resolution engine, we ensure our overrides apply exactly where we intend without accidentally breaking other sections of the dashboard.
