Hi,

i'm newbie in django and i'm writing a model to record a general
booking in a particular date for a particular item
The booking model looks like this:

class Booking(models.Model):
    item = models.ForeignKey(Item)
    startDate = models.DateField("From")
    endDate = models.DateField("To")

obviously i want to check if the item is available for the selected
dates before create a new booking.

I've to ckeck it via a database trigger or there is a django method to
do this?

p.s. I'll use this model both in django admin and in a custom user
interface.
