Django application deployment on Heliohost.org problems

Question

I've got an account at heliohost.org (Johnny Server) and I'm desperately trying to deploy a most simple Django application without any success. It's actually a very simple test application to check everything works fine, but it doesn't.

There are several error logs:

And these are the most important files' contents:

.htaccess:

RewriteBase /

RewriteRule ^(admin_media/.*)$ - [L]
RewriteRule ^(dispatch\.wsgi/.*)$ - [L]
RewriteRule ^(.*)$ /InformeSO/dispatch.wsgi/$1 [QSA,PT,L]

dispatch.wsgi :

import os, sys

# edit your username below
sys.path.append("/home/alber80/public_html")

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'InformeSO.settings'

application = get_wsgi_application()

settings.py:

Although I just realised I'm trying to deploy a Python / Django application which references some modules that might not be available on Heliohost.org, because this site doesn't allow shell access, please let me know if you come up with the issue.

Thank you very much in advance.

Answer 1

Try changing ALLOWED_HOSTS = [] to

ALLOWED_HOSTS = ['*']

Answer 2

Thank you for your answer. I already tried that and it gives another error saying that it cannot find the template referred in the code. I have modified the paths in the code and also the directory structure.

Answer 3

I already solved it by specifying the absolute path of the html document, instead of relative path. Thank you very much for your help. :-)
