DJANGO - Models.Forms - Usuarios - django

Question

I'm trying to save and retrive the data owned by the user.
I mean, in one Sqlite3 DB I store the tables for all users but each one has their one data store in it, how can I give each one their own data.
this are my models, view and form
MODEL.PY
class Cuentas (models.Model):
rubro_cta = models.ForeignKey(TipoC, on_delete=models.CASCADE, verbose_name = u'Tipo')
sub_rubro_cta = models.ForeignKey(Sub_rubro, on_delete=models.CASCADE, verbose_name = u'Sub Rubro')
titulo_cuenta = models.CharField(max_length=50)
detalle_cuenta = models.CharField(max_length=60)
importe_cuenta = models.FloatField()
def save(self, *args, **kwargs):
self.importe_cuenta = round(self.importe_cuenta, 2)
super(Cuentas, self).save(*args, **kwargs)
def __str__(self):
return self.detalle_cuenta
FORMS.PY
class CuentasForm (forms.ModelForm):
class Meta:
model = Cuentas
fields = ['rubro_cta', 'sub_rubro_cta', 'detalle_cuenta', 'importe_cuenta']
labels = {
'rubro_cta': _('Cuenta'),
'sub_rubro_cta': _('Tipo'),
'detalle_cuenta': _('Detalle'),
'importe_cuenta': _('Importe'),
}
VIEWS.PY
#login_required
def carga (request):
if request.method == 'POST':
form = CuentasForm(request.POST)
if form.is_valid:
form.save()
return redirect('balance')
else:
form = CuentasForm()
return render (request, "ProyetoWebApp/carga.html",{"form": form})

Answer 1

you have to add a foreign key field to user in your Cuentas class:
class Cuentas (models.Model):
user = models.ForeignKey(User, models.CASCADE)
...
in your view add this code for GET method:
info = None
if request.method == 'GET':
info = Cuentas.objects.get(user=request.user)
return render (request, "ProyetoWebApp/carga.html",{"form": form, "info":info})
