I have tried differents methods that i have founding in the internet but not function. all cases return error in the momento to record a row.

My Model:
class Entities(models.Model):
#class Category(models.Model):
id = models.BigAutoField(primary_key=True)
code = models.CharField(verbose_name='Código', max_length=10, blank=False, unique=True,
help_text='Codigo de entidad.')
name = models.CharField(max_length=150, verbose_name='Nombre', unique=True,
help_text='Nombre de la entidad.')
desc = models.CharField(max_length=500, null=True, blank=True, verbose_name='Descripción',
help_text='Descripción de la entidad.')
name_report = models.CharField(verbose_name='Nombre Reporte', max_length=100, blank=False, unique=True,
help_text='Rellenar para ACTIVAR el reporte')
long_desc = models.CharField(verbose_name='Descripción Larga', max_length=800, blank=True,

help_text='Idioma del reporte')
user = models.ForeignKey(User, default=0, verbose_name='Usuario', on_delete=models.DO_NOTHING)
date_created = models.DateTimeField(default=timezone.now, verbose_name='Creado', blank=False, unique=False)
date_updated = models.DateTimeField(default=timezone.now, verbose_name='Actualizado', blank=False, unique=False)
historical = HistoricalRecords()

return item

My CreateView:
class entitiesCreateView(LoginRequiredMixin, ValidatePermissionRequiredMixin, CreateView):

if action == 'add':
form = self.get_form()
data = form.save()
else:
data['error'] = 'No ha ingresado a ninguna opción'
except Exception as e:
data['error'] = str(e)
return JsonResponse(data)

My Form:

}
),
}
def save(self, commit=True):
data = {}
form = super()
try:
if form.is_valid():
**self.instante.user = self.request.user**
form.save()
else:

return data

SOLVED.
Adding, in the view, the line :
form.instance.user = self.request.user
full Createview would be :
class entitiesCreateView(LoginRequiredMixin, ValidatePermissionRequiredMixin, CreateView):
model = Entities
form_class = EntitiesForm
template_name = 'Entities/create.html'
success_url = reverse_lazy('erp:entities_list')
permission_required = 'add_Entities'
url_redirect = success_url
def dispatch(self, request, *args, **kwargs):
return super().dispatch(request, *args, **kwargs)
def post(self, request, *args, **kwargs):
data = {}
try:
action = request.POST['action']
if action == 'add':
form = self.get_form()
form.instance.user = self.request.user <============================
data = form.save()
else:
data['error'] = 'No ha ingresado a ninguna opción'
except Exception as e:
data['error'] = str(e)
return JsonResponse(data)
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['title'] = 'Creación de una Entidad'
context['entity'] = 'Entidades'
context['list_url'] = self.success_url
context['action'] = 'add'
return context

If you want to save additional data into form you can commit=False for this...
