WSGIRequest error using django_model_comments - django

Question

Sorry to post yet another question related to the error:
'WSGIRequest' object has no attribute 'find'
But I really can't find the answer anywhere.
I'm trying to use the django_model_comments app, which extends django's included comment app.
Did everything the page tells, however when running the server, I get the following:
Environment:
Request Method: GET
Request URL: http://localhost:8000/feed/1

Template error:

Exception Type: AttributeError at /feed/1
Exception Value: 'WSGIRequest' object has no attribute 'find'
And the error happens when a templatetag is used:
html = "{% load model_comment_tags %} \
{% get_comment_form for feed as post_form %}\
{% render_comment_form post_form %}"
t = template.Template(html)
html = t.render(RequestContext(request, {'feed': private_feed}))
I've checked all my middleware, the order of apps, deleted .pyc files, and made all sorts of experiments in the template.

Answer 1

There's a bug in the django_model_comments library, because here they pass the HttpRequest object, not a string which is what the Url class here is expecting, so instead it should call the build_absolute_uri() method on the request object and then pass the string to the Url class.
So basically replace
unicode(Url(request))
with
unicode(Url(request.build_absolute_uri()))
