I am working with a laptop rental program, and I was wondering if
there is a better way to do this lookup. This works fine, but it seems
like it could be better.
from django.db import models
class Laptop(models.Model):
def laptops_out_on(date):
'get a list of laptops out on a given day'
result = Laptop.objects.none()
for x in Rental.objects.filter(checkout__lte=date,
checkin__gte=date):
result = result | x.laptops.all()
return result
laptops_out_on = staticmethod(laptops_out_on)
class Rental(models.Model):
checkout = models.DateField(blank=True)
checkin = models.DateField(blank=True)
laptops = models.ManyToManyField(Laptop, blank=True)
Thanks,
Collin
