process_view() is not called on 404

[jooadam]

I have middleware implemented using process_view(), which don’t get called when the 404 view runs in DEBUG=False.

It works for me. Please reopen the ticket if you can debug your issue and provide more details or a sample project. If you're having trouble understanding how Django works, see TicketClosingReasons/UseSupportChannels for ways to get help.

process_view() is run after the URL is resolved. (That's how the view callback parameter is populated.) So, if resolution raises a 404, process_view() will not be called. This is expected AFAICS.

Replying to Carlton Gibson:

I would definitely not expect this, or for that matter, to reference the other issue I opened, that errors in a 404 not get logged. Django calls error handlers views, so I would expect them to work the same way as ordinary views, or call them something else. Or the very least, document that they are exceptional.
