Hi Ciuni,
Maybe your url already is path('updateTabacchi/<tabacchi_id>', I think
question is {{ form }}.
{{ form }} is to render fields without id. Add the <input /> if you want to
get the id from request.POST:
<form class="form-horizontal" role="form" method="POST">
{% csrf_token %}
<input name="tabacchi_id" value="{{ tabacchi.id }}" />
{{ form}}
