Cannot locate view in Django MVC

I'm trying to get started on a simple project to display a bit of HTML. However when I run my code I cannot seem to locate the html file. I am following what the tutorial on the Django website says

"Within the templates directory you have just created, create another directory called polls, and within that create a file called index.html. In other words, your template should be at polls/templates/polls/index.html. Because of how the app_directories template loader works as described above, you can refer to this template within Django simply as polls/index.html."

SO I put my index.html into 

    homepage/templates/homepage/index.html

I have not yet added anything to my models.py

proj urls.py:

    from django.conf.urls import include, url, patterns

    urlpatterns = patterns('',
        url(r'homepage/',include('homepage.urls', namespace = "homepage")),
    )

app urls.py

    from django.conf.urls import patterns, url
    from homepage import views

    urlpatterns = patterns('',
        url(r'^$', views.index, name = 'index'),
    )

views.py:

    from django.http import HttpResponse
    from django.template import RequestContext, loader

    def index(request):
        template = loader.get_template('homepage/index.html')
        return HttpResponse(template)
    )

******UPDATE************

So with a bit of tinkering I seem to be able to grab the HTML file. However, the display of this HTML file is not behaving correctly. For instance, if I were to have this bit:

    <!DOCTYPE html>
    <html>
    <body>

    <form>
    First name: <input type="text" name="firstname"><br>
    Last name: <input type="text" name="lastname">
    </form>

    </body>
    </html>

The output would be a blank page. The page source would display:

    <Text Node: '<!DOCTYPE html>
    <html>
    <b'>

Not sure why it is behaving this way. Would it have to do withi my having django-pipeline installed and also twitter bootstrap?

The problem is with return HttpResponse(template). The HttpResponse accepts content for it's first argument. The content could be anything that has a string representation (implements either __str__ or __unicode__, depending on passing Content-Encoding header to the response and it's charset) or is iterable. In the latter case, all elements yield by it have to representable by a string.

The issue you are experiencing is that you are passing a Template object to the response, which is iterable (implements __iter__ method). Iterating the template yields all the compiled nodes. The nodes themselves implement __repr__ which is used when __str__ is missing. And the HttpResponse, if content is iterable, returns all elements that are yield from iterating the iterable.

You can simulate this:

from django.http import HttpResponse
from django.template import RequestContext, loader

def index(request):
    template = loader.get_template('homepage/index.html')
    for n in template:
        print n
    return HttpResponse(template)
