Cannot get this ModelForm view to save to the db, what am I doing wrong please

[MikeKJ]

Cannot seem to get .save() to write to the db

This is the model


class Customer(models.Model):
email = models.EmailField()
postcode = models.CharField(max_length=10)
def __unicode__(self):
return self.email
def save(self):
self.postcode=upper(self.postcode)
super(Customer, self).save()


This is the view:


class RegisterForm(ModelForm):
class Meta:
model = Customer

def register(request):
form = RegisterForm(request.POST)
if form.is_valid():
email = form.cleaned_data['email']
postcode = form.cleaned_data['postcode']
postcode = upper(postcode)
try:
user = Customer.objects.all().filter(email=email).filter(postcode=postcode)[:1]
if user:
error = "You have already registered this email address and postcode, please login."
return render_to_response("customer/register_form.html", {'error': error, 'form': form, 'content': content,},context_instance=RequestContext(request))
except Customer.DoesNotExist:
cust_obj = Customer(email=email, postcode=postcode)
cust_obj.save()
return HttpResponseRedirect('/registration-thankyou/')

Also tried

new_user = form.save(commit=False)
new_user.save()

It isn't throwing any errors just not saving to the table

Cheers for any insight/help
