Answer 1

if request.method == "POST":

    if form.is_valid():
        # ....
    return HttpResponseRedirect('/login/')  # not indented

The return is unindented out of the is_valid() block. So, a POST, regardless of the form’s validity, will redirect. Change to

if request.method == "POST":

    if form.is_valid():
        # ....
        return HttpResponseRedirect('/login/')  # indented

Update:

def clean_username(self):
    username = self.cleaned_data['username']
    try:
        User.objects.get(username=username)
    except User.DoesNotExist:
        return username

        raise forms.ValidationError("That username  already exists. Please select another")

This is wrong; you can’t raise after you return. The raise should go in the try block.

def clean_username(self):
    username = self.cleaned_data['username']
    try:
        User.objects.get(username=username)
        raise forms.ValidationError("That username already exists. "
                                    "Please select another")
    except User.DoesNotExist:
        return username
