I have a Django-Server inside a Docker and would like to be able to do remote-debug my scripts. The arrow-keys just won't work. I'm getting 

(Pdb) ^[[A

instead of something useful. I'm just using a plain terminal on Ubuntu. No IDE or anything fancy.

As stated here I rewrote my docker-compose and it works with this line just fine:

__import__("remote_pdb").set_trace(host='0.0.0.0', port=4444)

With telnet I'm able to use most features of the pdb: telnet 0.0.0.0 4444 What's not working are the arrow-keys. Someone had that problem as well and I installed readline as this guy had the same problem: Python interactive mode history and arrow keys

dnf install ncurses-devel
pip3 install readline

No changes. (Installation works. I can import readline). I'm assuming the issue might come from the telnet. So I'm thinking of switching to ssh -t.

But now I'm supposed to log in:

ssh -t 0.0.0.0 -P 4444
qohelet@0.0.0.0's password:

There is no password. It's just a Docker. Also I wouldn't know the username.

I keep searching dand 2017 just called. I'm supposed to user gnureadline. No difference:

(Pdb) import gnureadline
(Pdb) ^[[A

I'm stuck now.

  • @user13182570 - Trying to debug as much as I can in Unit-Tests. It's a more proper way I assume. So my views.py is as compact as possible. All the functionality is moved to other classes – Qohelet Sep 18 '22 at 14:02
