        return render(request, 'form2.html', {'form': form})

    if request.method == 'POST':
        form = UserForm(request.POST)
        if not form.is_valid():
            return render(request, 'form2.html', {'form': form})
        form.instance.isAdmin = 0
        form.instance.creator = request.user_info.uid
