    Any idea why it brings me back to the same page when I submit the form?

    ahh ok. The tutorial emphasized RequestContext for the view that processes the form.

    Yeah, I changed that and I'm not getting an error anymore it's just taking me back to the same page. I'll dabble some more from here. Thanks!

    same html viewed from the browser 

    <form action="login.html" method="post">

    <input type="text" name="username" id="Username" value="Username" />
    <input type="text" name="password" id="Password" value="Password" />
<input type="submit" value="Vote" />
</form>

    Here's what I got from the shell. I don't know if this has everything you need. Especially since I wasn't able to pass along a "request" into the RequestContext 

    >>> print t.render(Context())
/usr/lib/python2.6/dist-packages/django/template/defaulttags.py:52: UserWarning: A {% csrf_token %} was used in a template, but the context did not provide the value.  This is usually caused by not using RequestContext.
  warnings.warn("A {% csrf_token %} was used in a template, but the context did not provide the value.  This is usually caused by not using RequestContext.")
<form action="login.html" method="post">

    <input type="text" name="username" id="Username" value="Username" />
    <input type="text" name="password" id="Password" value="Password" />
<input type="submit" value="Vote" />
</form>

>>> print t.render(RequestContext())
Traceback (most recent call last):
  File "<console>", line 1, in <module>
TypeError: __init__() takes at least 2 arguments (1 given)
>>> print t.render(RequestContext(request))
Traceback (most recent call last):

    I'm not sure if this is what you're looking for. This is the html of the error page.

  <a

  ensure:</p>

  <ul>
    <li>The view function uses <a
    href='http://docs.djangoproject.com/en/dev/ref/templates/api/#subclassing-context-requestcontext'<code>RequestContext</code></a>
    for the template, instead of <code>Context</code>.</li>

    <li>In the template, there is a <code>{% csrf_token
    %}</code> template tag inside each POST form that
    targets an internal URL.</li>

    <li>If you are not using <code>CsrfViewMiddleware</code>, then you must use
    <code>csrf_protect</code> on any views that use the <code>csrf_token</code>

    template tag, as well as those that accept the POST data.</li>

  </ul>

  <p>You're seeing the help section of this page because you have <code>DEBUG =
  True</code> in your Django settings file. Change that to <code>False</code>,
  and only the initial error message will be displayed.  </p>

  <p>You can customize this page using the CSRF_FAILURE_VIEW setting.</p>

    yeah, my original attempt looks like this. Same error message both ways. 

    # Create your views here.
from django.template import Context, RequestContext, loader
from login.models import Username
from django.http import HttpResponse
from django.shortcuts import render_to_response
from django.core.context_processors import csrf

def index(request):
    t = loader.get_template('login/index.html')
    return render_to_response('login/index.html')

def login(request):
    return render_to_response("login/login.html", context_instance=RequestContext(request))

    It's rendering correctly but now I have a CSRF token failure. I'm doing everything according to the tutorials though. Any idea? 
    Reason given for failure:

    No CSRF or session cookie.


    template 
    <form action="login.html" method="post">
{% csrf_token %}
    <input type="text" name="username" id="Username" value="Username" />
    <input type="text" name="password" id="Password" value="Password" />
<input type="submit" value="Vote" />
</form>



    views.py 
    # Create your views here.
from django.template import Context, RequestContext, loader
from login.models import Username
from django.http import HttpResponse
from django.shortcuts import render_to_response

def index(request):
    t = loader.get_template('login/index.html')
    return render_to_response('login/index.html')

def login(request):
    c = {}
    c.update(csrf(request))
    return render_to_response("login/login.html", c)

    Thanks

    Is there a way render a template object that has no variables? I tried doing t.render() but I got an error saying render needs at least one parameter.

    My understanding was the render method replaces all django variables with their values. Since I have no variables in my template why is this necessary?
