In Django I can't save my model's new content - database

Question

Once again I have a small problem to get this done in django. But at least you guys help me understand things better.
Here is my view:
def editUserprofile(request):
rc = context_instance=RequestContext(request)
u=request.user
if request.method=='POST':
form = UserProfileEdit(request.POST, request.FILES)
if form.is_valid():
u = UserProfile.objects.get(user=u)
u.avatar = request.FILES['avatar']
u.first_name = form.cleaned_data['first_name']
u.last_name = form.cleaned_data['last_name']
u.email = form.cleaned_data['email']
u.country = form.cleaned_data['country']
u.date_of_birth = form.cleaned_data['date_of_birth']
u.save()
return HttpResponseRedirect("/editprofile")
else:
u = UserProfile.objects.get(user=u)
form = UserProfileEdit()
return render_to_response('users/editprofile.html',
{'form':form, 'u':u},
rc)
No errors but my model doesn't get modified.. here is my template too:
<form method="POST" action=".">
{% csrf_token %}
{% if u.avatar %}
<img src="{{ MEDIA_URL }}{{ u.avatar }}" height="80px" />
{% else %}
<p>You have no avatar</p>
{% endif %}
<p>Change Avatar: {{form.avatar}}</p>
<br />
{% if u.first_name %}
<p>First Name: {{u.first_name}}</p>
{% else %}
<p>First Name: No first name added </p>
{% endif %}
<p>Modify:{{form.first_name}}</p>
<br />
{% if u.last_name %}
<p>Last Name: {{u.last_name}}</p>
{% else %}
<p>Last Name: No last name added </p>
{% endif %}
<p>Modify:{{form.last_name}}</p>
<br />
{% if u.email %}
<p>Email: {{ u.email }}</p>
{% else %}
<p>Email: No email added</p>
{% endif %}
<p>Modify:{{ form.email }}</p>
<br />
{% if u.date_of_birth %}
<p>Date of birth: {{ u.date_of_birth }}
{% else %}
<p>Date of birth: No birthday added </p>
{% endif %}
<p>Modify:{{form.date_of_birth}}</p>
<br />
{% if u.country %}
<p>Country: {{ u.country }}</p>
{% else %}
<p>Country: No Country added</p>
{% endif %}
<p>Modify:{{form.country}}</p>
<br />
<input type="submit" value="Save Changes">
</form>
Hope you can help me guys..!

Is form.is_valid() True in your form validation ?
