Question on Django: Deploying on a production server Cannot find templates.

Shh226 · 06-29-2010, 04:06 AM

Hello, I seem to have a problem with deploying Django on a production server using Apache. For those who don't know, Django is a is a web framework written in python coding and some html.

I seem to get this error - 'TemplateDoesNotExist at /" "/' .so for any url that requires a template. The other url seem to work fine e.g. (admin & admin/doc works because it does not require a template).

The strange thing is when I use Django Development server python manage.py runserver, The Django runserver can find the templates without any problem. I don't understand what the problem is.

Here are some addition coding

settings.py

PHP Code:
