You need to understand what ALLOWED_HOSTS does if you want to ever deploy your app. Please read it.

https://docs.djangoproject.com/en/1.5/ref/settings/#allowed-hosts

Check your settings in the shell

>>> from django.conf import settings as s

>>> s.DEBUG

True

>>> s.ALLOWED_HOSTS

['.example.com', '192.168.0.2']

If your DEBUG is False and your ALLOWED_HOSTS is an empty list [] then you will not get far. You will get a "SuspiciousOperation: Invalid HTTP_HOST header (you may need to set ALLOWED_HOSTS)" message.

You can try putting something like this into the template (pretty much straight from the Django blog example), and it will tell you nicely when it has nothing matching your query or if your db is empty:

{% block featured_posts %}

  {% if featured_posts_list %}

    {% for blog_post in featured_posts_list %}

        <p>{{ blog_post.title }}</p>

        <br>

    {% endfor %}

  {% else %}

    <p>No posts found</p>

  {% endif %}

{% endblock %}

You might also want to ensure that your view is rendering the right template and that the template hierarchy is correct (ie. {% extends "my_templates/base.html" %} is at the top of your template and it is correct). If your parent template that you're extending doesn't have a block named 'featured_posts' then it won't display anywhere. You won't see the "No posts found" message nor will you see your list of blogs - nada.

If there is an exception in the shell, it will print out a trace. This is an actual Dj1.5 trace from a made up exception I planted in the view. You can also put objects like your queryset into the Exception message and see if your set is producing what you think it should be.

>>> from django.test import Client

>>> c = Client()

>>> c.get('/')

Internal Server Error: /

From the server; I am getting the page I need but the block where the data from the view in question is supposed to be comes out empty.

I am indeed geting the ALLOWED_HOSTS warning, which I don't fully understand and don't know hoe to fix. I do have ALLOWED_HOSTS = ('localhost', '.local') and DEBUG = True as I read in Rod's excellent tutorial, but that did not help.
