instance is not updated, using forms save () Django

Question

instance is not updated, using forms save () Django.

Could anyone help?

save() got an unexpected keyword argument 'cpnj'

views

cliente = Cliente.objects.get(user=request.user.id, pk=pk)
 if request.method == 'POST':
        form = ClienteForm(request.POST)
        if form.is_valid():
            form.update(instance=cliente, validated_data=form.cleaned_data)
            return redirect('clienteEdit', pk)

Forms

def update(self, instance, validated_data, context):
        print(instance)
        instance.save(**validated_data)

It looks like your model object Cliente and form ClientForm have a mismatch in one of the fields. Does your model object Cliente have a field called cpnj?

for updating I suggest you change the fields manually like this:

cliente = Cliente.objects.get(user=request.user.id, pk=pk)
 if request.method == 'POST':
        form = ClienteForm(request.POST)
        if form.is_valid():
            cliente.cpnj = form.cleaned_data['cpnj']
            cliente.save()
            return redirect('clienteEdit', pk)

Yes. Yes. class ClienteForm(forms.Form): cpnj = forms.CharField()

class Cliente(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) cpnj = models.CharField(max_length=14)

i added an edit to my answer, see if that works, please note that form.cleaned_data['cpnj'] may not be correct since I dont know what its called inside the ClienteForm class
