I'm getting a strange error that only occurs on the live server. My Django templates directory is set up like so
base.html
two-column-base.html
portfolio
index.html
extranet
base.html
index.html
The portfolio pages work correctly locally on multiple machines. They inherit from either the root base.html or two-column-base.html. However, now that I've posted them to the live box (local machines are Windows, live is Linux), I get a TemplateSyntaxError: "Caught TemplateDoesNotExist while rendering: base.html" when I try to load any portfolio pages. It seems to be a case where the extends tag won't work in that root directory (???). Even if I do a direct_to_template on two-column-base.html (which extends base.html), I get that error. The extranet pages all work perfectly, but those templates all live inside the /extranet folder and inherit from /extranet/base.html.
Possible issues I've checked:
file permissions on the server are fine
the template directory is correct on the live box (I'm using os.path.dirname(os.path.realpath(__file__)) to make things work across machines)
files exist and the /templates directories exactly match my local copy
removing the {% extends %} block from the top of any broken template causes the templates to render without a problem
manually starting a shell session and calling get_template on any of the files works, but trying to render it blows up with the same exception on any of the extended templates. Doing the same with base.html, it renders perfectly (base.html also renders via direct_to_template)
Django 1.2, Python 2.6 on Webfaction. Apologies in advance because this is my 3rd or 4th "I'm doing something stupid" question in a row. The only x-factor I can think of is this is my first time using Mercurial instead ofsvn. Not sure how I could have messed things up via that.
EDIT: One possible source of problems: local machine is Python 2.5, live is 2.6.
Here's a traceback of me trying to render 'two-column-base.html', which extends 'base.html'. Both files are in the same directory, so if it can find the first, it can find the second. c is just an empty Context object.
>>> render_to_string('two-column-base.html', c)

I'm wondering if this is somehow related to the template caching that was just added to Django.
EDIT 2 (per lazerscience):
template-related settings:
import os
PROJECT_ROOT = os.path.dirname(os.path.realpath(__file__))
TEMPLATE_DIRS = (
os.path.join(PROJECT_ROOT, 'templates'),
)
sample view:
def project_list(request, jobs, extra_context={}):
context = {
'jobs': jobs,
}
print context
context.update(extra_context)
return render_to_response('portfolio/index.html', context, context_instance=RequestContext(request))
The templates in reverse-order are:
http://thosecleverkids.com/junk/index.html
http://thosecleverkids.com/junk/portfolio-base.html
http://thosecleverkids.com/junk/two-column-base.html
http://thosecleverkids.com/junk/base.html
though in the real project the first two live in a directory called "portfolio".
