Login page does not exist (500 Internal Service Error)

[MatthewRalston]

Hello everyone. I have a fresh production install of cloudlaunch on RHEL6 configured with PostgreSQL and Nginx, following the README. When I access "my-server:portnum/admin" page, I receive a 500 error indicating that the login.html page could not be found.

I cannot reproduce this and searching for the exception doesn't seem to lead anywhere either.
Django Admin (including index.html) is located under Django's contrib dir (/srv/cloudlaunch/.cl/lib/python2.7/site-packages/django/contrib/admin/templates).

The only thing I noticed is that your venv is in ~/.pyenv. So did you change paths in Procfile* and supervisor confs to reflect that because the instructions and consequently those scripts are currently hard coded to use the virtualenv from /srv/cloudlaunch/.cl?

[MatthewRalston]

The virtualenv, courtesy of pyenv-virtualenv, is located in ~/.pyenv/versions and is called cloudlaunch. Then I simply symlinked /srv/cloudlaunch/.cl to the virtualenv directory. I do not see the templates directory in the django/contrib/admin directory.
If I understand correctly, django searches for an application specific login template at a path relative to the root of the application (/srv/cloudlaunch/cloudlaunch/templates/admin/login.html). If this does not exist, it checks for a templates through the following, which makes user of the TEMPLATE_DIRS/DIRS variable in settings.py:
Using loader django.template.loaders.app_directories.Loader
/home/ralstonm/.pyenv/versions/cloudlaunch/lib/python2.7/site-packages/bootstrap_toolkit/templates/admin/login.html (File does not exist)

I'm not sure why your django installation contains these templates... Can you confirm that my pypy packages are correct from the pip freeze above?

/srv/cloudlaunch >/bin/ls .cl/lib/python2.7/site-packages/django/contrib/admin/
actions.py   filterspecs.py   forms.py   helpers.py   __init__.py   models.py   options.py   sites.py   templatetags  util.pyc       validation.pyc  widgets.py

This is the output from my pip freeze:

There are differences with argparse, gunicorn, meld3, requests but none of those seem related.

If you’re missing dirs under the Django installation path, perhaps try reinstalling Django?

[MatthewRalston]

Yes. I uninstalled the django version installed via pip, downloaded source, and ran setup.py. This produced the correct directory structure reflecting the release 1.3.7 for Django on github. This solved my problem. Thank you.
