Having to validate the data at every possible form location doesn't seem very DRY to me. I should be able to put a single set of validation rules directly in the model so any form I write in the future has to validate against them. > See http://www.djangoproject.com/documentation/forms/#validators for a > description of how validators work.

The newforms page doesn't have much about validation on it: http://www.djangoproject.com/documentation/newforms/ Do the same validation techniques apply from the old forms system to the newforms? > Suffice it to say that, in your case, when you submit a string as part > of a form submission to go into your field, Django will ensure that it > is non-empty, because you have blank=False. That doesn't seem to be the case for this particular field I have: class List(models.Model): name = models.CharField(maxlength=32, blank=False, null=False) > python manage.py shell In [1]: import datetime In [2]: from mysite.groceries.models import List In [3]: l = List(name='', created_at=datetime.datetime.now()) In [4]: l.save() In [5]: l.name Out[5]: '' What am I missing here? -- Greg Donald http://destiney.com/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
