If my model for Items is:
class Item(models.Model):
name = models.CharField(max_length=500)
startDate = models.DateField("Start Date", unique="true")
endDate = models.DateField("End Date")
Each Item needs to have a unique date range. for example, if i create an Item that has a date range of June 1st to June 8th, how can I keep and Item with a date range of June 3rd to June 5th from being created (or render an error with template logic)?
