如何从Django中的编辑表单更新对象？

你为什么不只使用ModelForm？

# forms.py# ...class MyForm(forms.ModelForm):    class meta:        model = MyModel# views.py# ...    def my_view(request, id):     instance = get_object_or_404(MyModel, id=id)    form = MyForm(request.POST or None, instance=instance)    if form.is_valid():        form.save()        return redirect('next_view')    return render(request, 'my_template.html', {'form': form})
