This is an enhancement of snippet #172. Here I use BeautifulSoup — far more easier to install through pip in a virtualenv, and possibly a bit more maintained — to format and properly indent the rendered HTML from templates.

I also added a check to only tidy contents in a DEBUG=True environment, regarding high impact on performance while doing so in production.

Last, it's compatible with Django 1.2.x.

import settings

from BeautifulSoup import BeautifulSoup


class PrettifyMiddleware(object):
    """HTML code prettification middleware."""
    def process_response(self, request, response):
        if settings.DEBUG and response['Content-Type'].split(';', 1)[0] == 'text/html':
            response.content = BeautifulSoup(response.content).prettify()
        return response

It's ok n1k0. Yours version of PrettifyMiddleware is better because #570 don't check DEBUG status.
