Getting the template name in django template

For debugging purposes, I would like to have a variable in all my templates holding the path of the template being rendered. For example, if a view renders templates/account/logout.html I would like {{ template_name }} to contain the string templates/account/logout.html.

I don't want to go and change any views (specially because I'm reusing a lot of apps), so the way to go seems to be a context processor that introspects something. The question is what to introspect.

Or maybe this is built in and I don't know about it?

From Django 1.5 release notes:

New view variable in class-based views context

In all generic class-based views (or any class-based view inheriting from ContextMixin), the context dictionary contains a view variable that points to the View instance.

Therefore, if you're using class-based views, you can use

{{ view.template_name }}

This works if template_name is explicitly set as an attribute on the view.

Otherwise, you can use

{{ view.get_template_names }}

to get a list of templates, e.g. ['catalog/book_detail.html'].

The easy way:

Download and use the django debug toolbar. You'll get an approximation of what you're after and a bunch more.

The less easy way:

Replace Template.render with django.test.utils.instrumented_test_render, listen for the django.test.signals.template_rendered signal, and add the name of the template to the context. Note that TEMPLATE_DEBUG must be true in your settings file or there will be no origin from which to get the name.

if settings.DEBUG and settings.TEMPLATE_DEBUG

    from django.test.utils import instrumented_test_render
    from django.test.signals import template_rendered


    def add_template_name_to_context(self, sender, **kwargs)
        template = kwargs['template']
        if template.origin and template.origin.name
            kwargs['context']['template_name'] = template.origin.name

    Template.render = instrumented_test_render

    template_rendered.connect(add_template_name_to_context)

Templates are just strings not file names. Probably your best option is to monkey patch render_to_response and/or direct_to_template and copy the filename arg into the context.
