TL;DR

The web server passes a request into Django's handler. Request middleware runs in configured order, URL resolution selects the first matching pattern, and Django calls the chosen view with the request and captured route values. The view coordinates application and model work and returns an HttpResponse, directly or through a rendered template. Response middleware then unwinds in reverse order before the server sends the response.

Overview
The MVT label is useful only when it helps explain the real path of a request.
The web server passes a request into Django's handler. Request middleware runs in configured order, URL resolution selects the first matching pattern, and Django calls the chosen view with the request and captured route values. The view coordinates application and model work and returns an HttpResponse, directly or through a rendered template. Response middleware then unwinds in reverse order before the server sends the response.

Stronger answer
Optional upgrade with examples, trade-offs, and sharper phrasing.
The view is the request-facing coordinator, not necessarily the place for every rule. A page view may select data and render a template, while an API view may return JSON through Django REST Framework, but both still use Django's routing and middleware pipeline. Failures can happen before the view during security middleware or routing and after it during rendering or response middleware, so handler-only logging gives an incomplete picture.
