Django and the POST request: unexpected behaviour with a form

urls.py

from django.conf.urls.defaults import patterns, include, url
import myproject.views

urlpatterns = patterns('', (r'^$', myproject.views.home), (r'^login$', apolla.views.login))

views.py

import django.http
import django.template
import django.shortcuts

def home(request):
    return django.http.HttpResponse("Welcome home!")

def login(request):
    un = request.POST.get('username')
    pa = request.POST.get('password')
    di = {'unam': un, 'pass': pa}   
    if un and pa:
        di['act'] = "/"
    else:
        di['act'] = "/login"
    return django.shortcuts.render_to_response('login.html', di, 
      context_instance=django.template.RequestContext(request))    
    # Why does this code not send me immediately to "/" with 
    # username and password filled in?

login.html

<html>
<head>
</head>
<body>
<form name="input" method="post" action="{{ act }}">
{% csrf_token %}
Username: 
<input type="text" name="username"><br>
Password: 
<input type="password" name="password"><br> 
<input id="su" type="submit" value="Submit"><br>
</form>
</body>
</html>

When I run the development server and go to localhost:8000/login and fill in a username and password and push the submit button I am not sent to localhost:8000/ as I expected from my login function in views.py, I just return to localhost:8000/login. But when I fill in any field and submit for the second time I get directed to localhost:8000.

I also used print un and print pa to see if the post caught the data from the username and password fields and it did from the first time, so why am I not being directed to localhost:8000/login from the first submit with both username and password fields filled in?

You can add redirects to your view by:

from django.http import HttpResponseRedirect

def foo_view(request):
    # ...
    return HttpResponseRedirect('/')
