`runserver 0`'s "Starting development server at <address>" doesn't work

[Ruslan Oleksandrovich Kovtun]

According to ​tutorial running

python manage.py runserver 0:8000

is the same as

python manage.py runserver 0.0.0.0:8000

but it's output

$ python manage.py runserver 0:8000                                     Watching for file changes with StatReloader                           
...
Starting development server at http://0:8000/ 
...

So that you can't use link "​http://0:8000/" in your browser. Output should be "Starting development server at ​http://0.0.0.0:8000/" when providing "0:8000" in command line in order to stay consistent with docs.

On a Mac I could click that link and have it take me to ​http://0.0.0.0:8000/

What OS are you on?

It might even be better to just explicitly change it to say "0.0.0.0" because at least then you can copy & paste it as well … Let's wait to see what the triage team decide 🤷‍♂️

According to the Diátaxis framework, ​a tutorial should provide only the minimum necessary explanation.

Even if we think the Changing the port box is relevant here (which we might not 🤔) I think the whole 0 is a shortcut bit could just be cut without loss. (That's just my take.)

There will be loss, because 0.0.0.0 is actually binded on 0 (opening 0.0.0.0 in browser gives dev server page) but browser can't recognize such shortcut, that is why it is TUI bug.

TUI should show "​http://0.0.0.0:8000/" when provided with "0:8000".

If you don't care just close the issue, I have reported an issue as clear as possible, good bye.

Pasting http://0:8000/ into Firefox works but not in Chrome. I think it would be reasonable to rewrite an address of 0 (zero) to 0.0.0.0 in ​runserver's output.
