python manage.py migrate - Error

[danfoxley]

In following steps to install on-premise, I'm stuck here.

Yep, also having the same error.

A little research

c555418 is the first commit that doesn't have that error, but it has another (so this problem was probably introduced in c5207e3):

(env) root@test1:/opt/amon# git checkout c555418781dbb2f3c9a23d41d3df2d17aea6ba4c
Previous HEAD position was c5207e3... Refactoring
HEAD is now at c555418... Cleanup

The latest commit that I could install with instructions is 773fdca

git checkout 773fdca && \
pip install -r /opt/amon/requirements.txt && \
python manage.py migrate

...
Applying auth.0008_alter_user_username_max_length... OK
Applying sessions.0001_initial... OK
Applying users.0001_initial... OK

(However, this version has another error deep inside: No module named amon.apps.notifications.mail.backends, possible fix: change EMAIL_BACKEND in /opt/amon/amon/settings.py to EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' and restart, doesn't work for me though, [Errno 111] Connection refused)

[slava-vishnyakov]

Ok, the best workaround for now that I've come up with:

# Install old working commit
cd /opt/amon && . /opt/amon/env/bin/activate && \
git checkout 773fdca && \
pip install -r /opt/amon/requirements.txt && \
python manage.py migrate

# Fix CSRF error (if you have it)
echo >> /opt/amon/amon/settings.py
echo 'CSRF_TRUSTED_ORIGINS = [host_struct.hostname,]' >> /opt/amon/amon/settings.py

# Update to master
cd /opt/amon && . /opt/amon/env/bin/activate && \
git checkout master && \
pip install -r /opt/amon/requirements.txt && \
python manage.py migrate && \
systemctl restart amon.service

Thanks for that, not sure I would have gotten there anytime soon.
Along with this: #172 I was able to get an install to work.
