Comment (by prestontimmons):
I found some interesting behavior while working on the debug messages.
Currently, the debug view is coupled to django.template.loader. To
generate a post-mortem, it loops through the loaders and calls their
get_template_sources api. This means there is no post-mortem output for
the cached or egg loader. Further, the post-mortem status messages assumes
the return values are filesystem paths.
I think we can do better than this. The information used in the post-
mortem is already available in Loader.get_template. I'm going to see if we
can pass that through instead as an attribute of TemplateDoesNotExist,
rather than recalculating it. This would remove the coupling and fix
things for the egg and cached loader.
