Question

How implement that the user in the Model Entities add automatically the user that is authenticated in django?
now, returning the following error:
error
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.
only, i need that, in the moment that create a row, the user field was the user that is authenticated.
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='Descripción larga. Máximo 800 caracteres.')
language = models.CharField(verbose_name='Idioma', max_length=2, choices=languages, default='ES',
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()
def __str__(self):
return self.name
def toJSON(self):
item = model_to_dict(self)
return item
class Meta:
verbose_name = 'Entidad'
verbose_name_plural = 'Entidades'
ordering = ['id']
My CreateView:
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()
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
My Form:
class EntitiesForm(ModelForm):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
# for form in self.visible_fields():
# form.field.widget.attrs['class'] = 'form-control'
# form.field.widget.attrs['autocomplete'] = 'off'
self.fields['code'].widget.attrs['autofocus'] = True
class Meta:
model = Entities
fields = '__all__'
exclude = ['user','date_created','date_updated']
widgets = {
'name': forms.TextInput(
attrs={
'placeholder': 'Ingrese un nombre',
}
),
'desc': forms.Textarea(
attrs={
'placeholder': 'Ingrese un nombre',
'rows': 3,
'cols': 3
}
),
}
def save(self, commit=True):
data = {}
form = super()
try:
if form.is_valid():
**self.instante.user = self.request.user**
form.save()
else:
data['error'] = form.errors
except Exception as e:
data['error'] = str(e)
return data

Answer 1

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...
def post(self, request, *args, **kwargs):
data = {}
try:
action = request.POST['action']
if action == 'add':
form = self.get_form()
form = form.save(commit=False)
form.user = 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)
