Django Template Syntax Error in Google App Engine

Question

I tried launching my Google App Engine app on localhost, and got a Django error I am stuck on.

"TemplateSyntaxError: Template 'base/_base.html' cannot be extended, because it doesn't exist"

I put the templates in a /templates, and then _base.html & index.html in /templates/base . Thanks! Emile @ proudn00b.com

The Error:

Traceback (most recent call last):
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/ext/webapp/__init__.py", line 511, in __call__
    handler.get(*groups)
  File "/Users/emilepetrone/code/thebuswheel/main.py", line 65, in get
    outstr = template.render(temp, { 'path': path })
….

…..
File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/django/django/template/loader_tags.py", line 58, in get_parent
    raise TemplateSyntaxError, "Template %r cannot be extended, because it doesn't exist" % parent
TemplateSyntaxError: Template 'base/_base.html' cannot be extended, because it doesn't exist

Referring to :

def get(self):

    path = self.request.path

    temp = os.path.join(
        os.path.dirname(__file__),
        'templates' + path)

    if not os.path.isfile(temp):
        temp = os.path.join(
            os.path.dirname(__file__),
            'templates/base/index.html')

    outstr = template.render(temp, { 'path': path })        
    self.response.out.write(outstr)

Another thing you can double check is to make sure one of the paths in the TEMPLATE_DIRS setting points to the root directory for your templates.

Also make sure it's a full absolute path in the setting, not relative to the project.
