LNDg cannot start using django v5.0+

I found the following error after successfully setup all steps

In the requirements.txt file, do the following change: Replace Django with Django==4.2.8

Then, re-run venv/bin/pip install -r requirements.txt (or wherever your venv is)

Django released v5 a few days ago which handles form choices a bit different (thus breaking things) and the requirements.txt would try to install the latest v5. If you rollback to Django v4 your problem will go away :)

Thanks @lacksfish for the root cause and interim fix! This issue will be resolved in the v1.8.0 release.

I see https://github.com/cryptosharks131/lndg/commit/fedef6d9199c6d5404f9af379331663426c36985 👍

OT: I have this running for about a good week now. Autofee seems to be working and adjusts every now and then. I have AR enabled as well as under 'Advanced Settings' I manually enabled AR for all my channels. Some have been immediately disabled by AR again. I think that's expected? Still, my channels are not really balanced, either completely full or completely empty.

Does this sound like it's working ? I'd love to route more payments, but not much is happening. Perhaps my channels are not good (directional-bias, etc) ?

[cryptosharks131]

You don't want to enable all individual channels for AR, only the ones you want to invest sats into restocking the outbound liquidity for (so you can resell it at a higher price). All channels that are not marked for AR will be potential sources to refill those selected channels. The Autopilot feature will enable and disable channels based on their historical flow rates, so it's possible this is why you saw this behavior.

This guide can help understanding the process a bit better as well. https://github.com/cryptosharks131/lndg/blob/master/quickstart.md

Successfully started lndg after changed Django==4.2.8. Thank you very much.

Just a hint for people using docker, you can change the Dockerfile to pick up your change to requirements.txt by adding a COPY line like this:

04:37 $ cat Dockerfile 
FROM python:3
ENV PYTHONUNBUFFERED 1
RUN git clone https://github.com/cryptosharks131/lndg.git /lndg
WORKDIR /lndg
COPY requirements.txt /lndg/requirements.txt
RUN pip install -r requirements.txt
RUN pip install supervisor whitenoise

And then re-run docker-compose build --no-cache to make a new image and try it again. I also deleted the lndg container and lndg image for good measure before running docker-compose up again.
