          exclude = {'is_staff','is_active','is_superuser','last_login','date_joined','user_permissions',}
  </code></pre>
  
  <p>View.py</p>

          form = addUseF()
      if request.method == "POST":
          form = addUseF(request.POST)
          if form.is_valid():
              form.save()
              return HttpResponseRedirect('/superUser/')
          else:
              ctx = {'form':form}
              return  render_to_response('adm/adduser.html',ctx,context_instance=RequestContext(request))
  
      ctx = {'form':form}
      return render_to_response('adm/adduser.html',ctx,context_instance=RequestContext(request))
  </code></pre>
