I have this model:
class House(models.Model):
Huisnumber = models.CharField(max_length=3)
Reservation = models.ForeignKey('Data', blank=True)
def __unicode__(self):
return self.Huisnumber
class Data(models.Model):
Name = models.CharField(max_length=30)
Arrival = models.DateField()
Departure = models.DateField()
def __unicode__(self):
return '%s %s %s' % (self.Naam, self.Arrival,
self.Departure)
And this query:
range = House.objects.exclude(
Reservation__Arrival__range=(Check_arrival, Check_departure)
).exclude(
Reservation__Departure__range=(Check_arrival, Check_departure)
)
This should get a list of houses which are available. This works fine
when only one date (reservation) is entered. When a house has two
reservations, only the last entry is evaluated. How should I handle
multiple entries?
