I'm trying to build a static site generator using Django (because its resourceful that way), and right now my problems are dealing with the Django command that is supposed to build my static site content into a directory. Apparently my 'NoneType' object has no attribute 'split', but I dont know what that 'NoneType' object is.

```

```

It seems that my problem lies in my command file, which I call `build`. The traceback also brings up my `views` file, which works well on its own (that is, my html files can be properly served on the local server), but I will include it anyway.

**build.py**

```
import os, shutil
from django.conf import settings
from django.core.management import call_command
from django.core.management.base import BaseCommand
from django.core.urlresolvers import reverse
from django.test.client import Client

def get_pages():
    for name in os.listdir(settings.STATIC_PAGES_DIRECTORY):
        if name.endswith('.html'):
            yield name[:-5]

class Command(BaseCommand):
    help = 'Build static site output.'

    def handle(self, *args, **options):
        """Request pages and build output."""
        if os.path.exists(settings.SITE_OUTPUT_DIRECTORY):
            shutil.rmtree(settings.SITE_OUTPUT_DIRECTORY)
        os.mkdir(settings.SITE_OUTPUT_DIRECTORY) 
        os.makedirs(settings.STATIC_ROOT)   
        call_command('collectstatic', interactive=False, clear=True, verbosity=0)
        this_client_will = Client()

        for page in get_pages():
            the_page_url = reverse('page',kwargs={'slug': page})      # PROBLEM SEEMS TO GENERATE STARTING HERE
            response = this_client_will.get(the_page_url)
            if page == 'index.html':
                output_dir = settings.SITE_OUTPUT_DIRECTORY
            else:
                output_dir = os.path.join(settings.SITE_OUTPUT_DIRECTORY, page)
                os.makedirs(output_dir)
            with open(os.path.join(output_dir, 'index.html'), 'wb', encoding='utf8') as f:
                f.write(response.content)

```

**views.py**

```
import os
from django.conf import settings
from django.http import Http404
from django.shortcuts import render
from django.template import Template
from django.utils._os import safe_join

# Create your views here.

def get_page_or_404(name):
    """Returns page content as a Django template or raise 404 error"""
    try:
        file_path = safe_join(settings.STATIC_PAGES_DIRECTORY, name)
    except ValueError:
        raise Http404("Page Not Found")
    else:
        if not os.path.exists(file_path):
            raise Http404("Page Not Found")

    with open(file_path,"r", encoding='utf8') as f:
        the_page = Template(f.read())

    return the_page

def page(request, slug='index'):
    """ Render the requested page if found """
    file_name = '{0}.html'.format(slug)
    page = get_page_or_404(file_name)
    context = {'slug': slug, 'page': page} 
    return render(request, 'page.html', context)   # THE TRACEBACK POINTS AT THIS LINE, TOO

```

and just in case it becomes useful to know, here is my **urls.py**:

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

urlpatterns = [
    url(r'^page/(?P<slug>[-\w]+)/$', 'sitebuilder.views.page', name='page'),
    url(r'^page$', 'sitebuilder.views.page', name='homepage'),
]

```

I find this frustrating, primarily because this problem seems to be tied to the reverse() function, as seen in the build module, and I havent had a great time using that function for as long as I can remember, but I dont know if this is really my problem. Can someone help me figure out where my issue is coming from and how to solve it (if you have any tips)? It would be much appreciated.
