python - Problem with form in Django -

i'm trying implement form let user change password.

here code:

forms.py

class changepasswordform(forms.form):     password1 = forms.charfield(widget = forms.passwordinput(), required = true)     password2 = forms.charfield(widget = forms.passwordinput(), required = true)      def clean_password2(self):         password1 = self.cleaned_data.get("password1", "")         password2 = self.cleaned_data["password2"]         if password1 != password2:             raise forms.validationerror("the 2 password fields didn't match.")         return password2      def save(self, *args, **kw):         self.user.set_password(self.cleaned_data['password1'])         print "pass setted."         self.user.save() 

views.py

def change_password(request):     form = changepasswordform()     if request.method == 'post':         form = changepasswordform(request.post, instance = request.user)         if form.is_valid():             password1 = form.cleaned_data['password1'];             password2 = form.cleaned_data['password2'];             print password1 + " == " + password2             form.save()             messages.success(request, "password updated!")             return httpresponseredirect('')      return render(request, 'change_password.html', {'form': form}) 

it doesn't work because user not defined. problem how pass user form. ideas? thanks.

just make parameter save method.

def save(self, user):     user.set_password(self.cleaned_data['password1'])     user.save()  ...   form.save(request.user)
