Django app - internal server error

Question

Hi,

I'm trying to deploy my django app which is working locally. However, I'm getting an internal server error in my webfaction deployment. I'm thinking this is a pythonpath problem since I don't get this error on my local installation?

This is what I get in my django log:

 File ".../django/lib/python2.6/django/utils/importlib.py", line 35, in import_module
 File ".../django/mydjangoapp/tagging/__init__.py", line 3, in <module>
from tagging.managers import ModelTaggedItemManager, TagDescriptor
TemplateSyntaxError: Caught ImportError while rendering: No module named tagging.managers

It seems that there is a problem with the "tagging" app. The tagging app is in my django folder though, and it includes managers.py.

I'm thinking this might be a pythonpath problem since the app works locally? How should I change my pythonpath to add the apps that are inside my django/mydjangoapp folder?

Thanks for any help.

Answer 1

The problem was that my project wasn't in my pythonpath. I had to add it myself.

There are several ways to do this. You can read about all of the different ways here: http://docs.webfaction.com/software/python.html#importerror

What I did was add the path to my app into the "myproject.wsgi" file:

Open /home/username/webapps/djangoapp/myproject/myproject.wsgi If there is no line such as

sys.path = ['/home/username/webapps/djangoapp/myproject'] + sys.path

Add it in there.

You can add more paths of course as well, check out the documentation link for more info.

Try the following:

from myproject.tagging.managers import ModelTaggedItemManager, TagDescriptor

Replace myproject with the name of your django project. If that doesn't fix it, feel free to open a support ticket and we can take a look at your application.

Hi, thank you for the fast reply. I tried this, but now it's giving the same error for "tagging.models". So it seems the "tagging" app doesn't work at all. I'll try to figure it out and open a support ticket if I can't get it working.

You might need to put myproject before tagging every time you import it. If you can't get it working, we'll be happy to help you if you open a support ticket.
