The Django Debug Toolbar is a powerful tool that provides insights into SQL queries, cache hits/misses, template rendering times, and more.

Installing Django Debug Toolbar

1. Install the package:

   
   pip install django-debug-toolbar
   

2. Add it to your INSTALLED_APPS:

   INSTALLED_APPS += ['debug_toolbar']
   

3. Add the middleware to your MIDDLEWARE:

   MIDDLEWARE += ['debug_toolbar.middleware.DebugToolbarMiddleware']
   

4. Configure the internal IPs:

   INTERNAL_IPS = ['127.0.0.1']
   

5. Include the Debug Toolbar URLs in your urls.py:

   
   from django.conf import settings
   from django.urls import include, path
   
   if settings.DEBUG:
       urlpatterns += [path('__debug__/', include('debug_toolbar.urls'))]
   

When you run your server, the Debug Toolbar will appear as a sidebar on your web pages.
