django-secure-mail installation fails

[vbretsch]

Hi there,
i installed django following these instructions: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-debian-9
after which i tried to install django-secure-mail following your instructions.
The pip install part works fine but migrating database settings via python manage.py migrate secure_mail unfortunately throws this error message:

(djangoenv) volker@debian10-django:~/django$ python manage.py migrate secure_mail
Traceback (most recent call last):

Thanks for reporting this, this is a bug. I'll see if I can fix this and push a new version to PyPI later tonight or this week.

In the meantime, the workaround is to set a SITE_NAME variable explicitly in your settings.py. Set the value to what you would like to pass to GnuPG as the name_real keyword argument. According to the GnuPG documentation that should be "The real name of the user identity which is represented by the key." I would recommend setting it to a human-readable version of you or your site/organization's name.

Just an update: I have been working on this a bit, and I have resolved this issue in a local branch. I will be pushing it to GitHub soon and pushing a release to PyPI hopefully later this week.

I have just pushed out version 1.2.0 to PyPI, which fixes this issue. Closing. If you find that the issue is not fixed, or if it gets reopened in the future (it shouldn't), comment here and I'll reopen it.
