Django debug toolbar is not working

[lucasmarchd01]

I just noticed that while working in my development environment (devcontainer setup), the Django debug toolbar doesn't show. Perhaps this was as a result of #1454?

I've got it to work by running request.META["REMOTE_ADDR"] to one of our views, which has exposed the port 172.24.0.4 as the IP host in the django container. So if I add this IP to INTERNAL_IPS it fixes the issue, but this solution is hardcoding the IP address which isn't really useful. Is there a way of making this dynamic in settings.py?

This works too, but not sure if it will be the same for everyone:

if DEBUG:
    import socket
    ip = socket.gethostbyname(socket.gethostname())
    INTERNAL_IPS += [ip[:-1] + "4"]
    INSTALLED_APPS.append("debug_toolbar")
    # debug toolbar must be inserted as early in the middleware as possible
    MIDDLEWARE.insert(0, "debug_toolbar.middleware.DebugToolbarMiddleware")

I was frustrated by this too the other day!

Was just about to post the same thing:

    import socket

    INTERNAL_IPS = [
        ".".join(socket.gethostbyname("host.docker.internal").split(".")[:-1]) + ".1"
    ]

What's odd to me is that this is similar to what the debug_toolbar already has in its callback:

https://github.com/jazzband/django-debug-toolbar/blob/7271cac9eacb7870200d6bc965c84eb91ba36714/debug_toolbar/middleware.py#L19-L38

Interesting. I remember when setting this up seeing this warning in their documentation:
django-commons/django-debug-toolbar#1854

But now it's gone. I think their solution assumed that the docker IP would always end with 1, but it ends in 4 for our (or my) case which is why it didn't work.

Now, while using the debug toolbar to try and see how many SQL queries are being made, I get the following error:

AttributeError at /
'Connection' object has no attribute 'status'

I think this is probably linked to django-commons/django-debug-toolbar#1754. We have django_debug_toolbar = "3.8.1" in our dev dependencies and psycopg 3.1.18 which are incompatible.
