Django - In local server all work fine but in GUnicorn django is filtering the bad a query

how are you? first of all sorry for my bad english.

I have a problem with my server in DigitalOcean. i have the server running in Django with postgres and in local i use SQLite.

In both i use Python 3.4 - in local windows and python 3.4.3 in DO Ubuntu with python 3.4.0

Have a problem filtering a query.

this is the model

# Create your models here.
class WorkOrder(models.Model):
    fk_client = models.ForeignKey(Client, verbose_name='Cliente')
    fk_store = models.ForeignKey(Store, verbose_name='Local')
    store_internal_order = models.CharField(verbose_name='Orden Interna',
                                            max_length=10,
                                            null=True,
                                            blank=True)
    sector = models.IntegerField(verbose_name='Sector',
                                 choices=SECTOR_CHOICES,
                                 default=1)
    article = models.CharField(verbose_name='Dispositivo', max_length=20)
    serial = models.CharField(verbose_name='Serial', max_length=25)
    work = models.CharField(verbose_name='Trabajo', max_length=40)
    article_details = models.CharField(verbose_name='Detalles Artículo',
                                       max_length=255, blank=True)
    cash_advance = models.DecimalField(verbose_name='Seña', max_digits=6,
                                       decimal_places=2,
                                       default=0)
    initial_price = models.DecimalField(verbose_name='Precio', max_digits=6,
                                        decimal_places=2,
                                        default=0)
    service_cost = models.DecimalField(verbose_name='Costo', max_digits=6,
                                       decimal_places=2,
                                       default=0)
    randpassw = models.CharField(default='12345', max_length=5, blank=True,
                                 null=True)
    warranty = models.PositiveSmallIntegerField(verbose_name='Garantía',
                                                default=0,
                                                blank=True,
                                                null=True)
    last_status = models.IntegerField(verbose_name='Estado',
                                      choices=STATUS_CHOICES,
                                      default=1)
    timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)

    def __str__(self):
        return str(self.id)

this is the view

def index(request):
    if not request.user.is_authenticated():
        return redirect('auth_login')

    title = "Lista de Ordenes"
    # Creamos el query para tomar las ordenes
    queryset = WorkOrder.objects.all()
    queryset = queryset.exclude(last_status=20)
    # Tomamos el filtro de sector
    sector_filter = request.GET.get('sector')
    # Tomamos filtro de ENTREGADAS
    # delivered = reqeust.GET.get('delivered')

    context = {
               'title': title,
              }

    if not request.user.is_staff:
        user_store = request.user.userprofile.fk_store
        # Añadimos otro filtro al queryset para tomar solo las del local
        # correspondiente al usuario
        queryset = queryset.filter(fk_store=user_store)
        store = Store.objects.get(name=user_store)

        context.update({'store': store})

    # Si hay un filtro de sector volvemos a filtrar el queryset
    if sector_filter:
        queryset = queryset.filter(sector=sector_filter)

    context.update({'queryset': queryset})

    paginator = Paginator(queryset, 7)  # Show 5 orders per page

    page = request.GET.get('page')
    try:
        orders = paginator.page(page)
    except PageNotAnInteger:
        # If the page is not an integer, deliver first page
        orders = paginator.page(1)
    except EmptyPage:
        orders = paginator.page(paginator.num_pages)

    context.update({'orders': orders})

    return render(request, "workorders/index.html", context)

Well here is my problem i have to filter all the work orders that have in the Last Status the Status "20" (int)

In local work perfect! i can see all the orders except the orders with last status 20. But in production in DigitalOcean VPS with gunicorn running. The query only show the orders with last status 1 and is filtering all the other orders.

i try first with this queryset queryset = WorkOrder.objects.filter(~Q(last_status=20))and after that i change for the queryset that you can see in my view. Both work fine in local but not in production.

any idea?

Thanks very much for your help!
