Hi there,
What would be the best way to make a model with two e-mail fields uniques?
I was thinking about writing some validation in the save() method but would
like to know whether Django has some built-in way to deal with it.
class Person(models.Model):
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
email1 = models.EmailField(null=True, blank=True)
email2 = models.EmailField(null=True, blank=True)
def __unicode__(self):
return self.last_name + ', ' + self.first_name
def save(self):
if (len(self.email1) == 0 and len(self.email2) == 0):
raise ValueError('At least one e-mail is needed to proceed.')
super(Member, self).save()
John = Person()
John.email1 = 'someEmail'
John.save()
Kane = Person()
Kane.email1 = 'anotherEmail
Kane.email2 = 'someEmail' #same email used by John on email1 field
Kane.save() #should raise error because email2 is already used by John on
email1 field
Thanks
