What is the best way to profile a view in Django?

I have developed an application using Django and everything is working fine but I don't know what's going on behind the scenes. I would like to know:

Is there a Middleware to handle this that I could install? Which are the best practices to profile my views?

Thanks

For people arriving in 2019+, django-debug-toolbar is still great, but just as a heads-up, most of the template profiling panes are broken in modern Django versions (2.0+).

Another good option these days is django-silk which has some beautiful timing profile visualization and graphing features, and django-live-profiler with a working fork for Django v2.0+ here.

The one project that meets all your requirements, with the exception of profiling, is the excellent django debug toolbar.

For standard profiling you need to use repoze.profile (which means you have to be running Django with WSGI interface such as mod_wsgi).

If you're hardcore and need to debug memory leaks use dozer (also a WSGI component).
