Can't load project (that worked on home computer) : Forums : PythonAnywhere

Can't load project (that worked on home computer)

Well my current project is simply bugging out on pythonanywhere. While it worked perfectly on my home pc.

The github location: https://github.com/pulli23/IFoxHuntGameSite

When I finally got around to set up everything correct (basically I used the wizard to create a new "app" called "IFoxHuntGameSite", then delete the main folder and finally cloned github), an error occurred when 'reloading website':

This error did not occur at all in my home project, what is the difference? At home I use django 1.9 btw?

You're not using Django 1.9 on PythonAnywhere because you haven't created a virtualenv with DJango 1.9 installed. Instruction here

Well adding a virtual environment solved "this" problem. However there are quite a few new problems:

This might be even more cryptic? Google reveals this is often a problem with the wsgi.py file. So when I go to /home/paul23/IFoxHuntGameSite/IFoxHuntGameSite/wsgi.py I do have:

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "IFoxHuntGameSite.settings")

application = get_wsgi_application()

Which is correct right? Or am I missing a major problem?

You're not setting sys.path in the WSGI file. Look at the end of this under Django-specific issues and see if that helps.

glenn | 10036 posts | PythonAnywhere staff | Dec. 5, 2015, 11:38 a.m. | permalink

I have to state I got nothing from that tutorial. Adding the lines:

import sys
path = "/home/paul23/IFoxHuntGameSite"
if path not in sys.path:
    sys.path.append(path)
os.environ["DJANGO_SETTINGS_MODULE"] = "IFoxHuntGameSite/settings.py"

To wsgi.py does not solve anything. - the page is also very cryptic with some syntax errors.

deleted-user-1134300 | 5 posts | Dec. 10, 2015, 5:20 p.m. | permalink

I think Glenn meant the PythonAnywhere WSGI file that's linked from the "Web" tab, in the "Code" section. The error you're getting suggests that your current WSGI file has the code for a Django < 1.7 app, and your app is actually a more recent version (1.9?)

giles | 12640 posts | PythonAnywhere staff | Dec. 10, 2015, 5:36 p.m. | permalink

Ah thanks giles (and glenn) - I'm now looking at the WSGI file in the web tab....

..... And there I notice a handy comment ("If using django 1.7 and above comment out those two lines....") which solved it. Kind of hidden "config" flag though.

deleted-user-1134300 | 5 posts | Dec. 10, 2015, 6:42 p.m. | permalink

Yup, it's a tricky one for us to work around. We're working towards a system where we can more easily upgrade all Django versions to 1.7 or higher for all versions of Python, and when we've done that it shouldn't be necessary.

Is everything working OK now?

giles | 12640 posts | PythonAnywhere staff | Dec. 13, 2015, 8:49 p.m. | permalink

Well yes, played my "game" (it was a simple gps-based game based on old fashioned hide and seek). Only I seem to have (unrelated) broken my error.log.

deleted-user-1134300 | 5 posts | Dec. 14, 2015, 12:55 a.m. | permalink

I'm sure we can figure it out, even if it's unrelated! What's broken about the error log?
