Question

I’m trying to make template.render() (import was: from google.appengine.ext.webapp import template) use a template located in a directory other than the root of the application.

I have a directory, called static, where I’d like to keep my templates. Or possibly, I’ll change that to static/templates later, but this doesn’t matter.

The problem? TemplateDoesNotExist: index.html, a sad exception.

This:

path = os.path.join(os.path.dirname(__file__), 'index.html')
logging.debug(path)
self.response.out.write(template.render(path, template_values))

.. works, but this:

path = os.path.join(os.path.dirname(__file__), 'static/index.html')
logging.debug(path)
self.response.out.write(template.render(path, template_values))

.. does not.

/static has been added to app.yaml, although it shouldn’t matter.

Thanks for any advice.

Adding /static to app.yaml does cause files in /static to be treated differently.

See http://code.google.com/appengine/docs/python/config/appconfig.html#Static_File_Handlers and note:

If you have data files that need to be read by the application code, the data files must be application files, and must not be matched by a static file pattern.

Templates are data files.
