One useful Django template tag is to retrieve the template filename from inside the template. Unfortunately, Django built in tags do not provide one for this. However, you can write a simple tag to accomplish this.

Here's are two tags, that return either the base filename or the full filename.

from django import template

register = template.Library()

@register.simple_tag(takes_context=True)
def basefilename(context):
    '''Returns filename minus the extension'''
    return context.template_name.split('.')[0]

@register.simple_tag(takes_context=True)
def fullfilename(context):
    '''Returns full filename with the extension'''
    return context.template_name

To be complete, tthere should be another tag that returns the filename with its entire path. But I haven't figured out how to do this -- at least from within the confines of the template tag framework.
