thanks for your reply!
i resolved using this code in the models.py before save():
def save(self):
if len(self.title)<6:
raise ValidationError("cannot be blank or small than 6
byte!")
it works for me!
but i find this code in django-tagging (http://code.google.com/p/
django-tagging/):
models.py:
from tagging.validators import isTag
name = models.CharField(validator_list=[isTag])
validators.py:
def isTag(field_data, all_data):
"""
Validates that ``field_data`` is a valid tag name.
"""
if not isinstance(field_data, unicode):
field_data = field_data.decode(settings.DEFAULT_CHARSET)
i like this way to define validator , but i t did not work for me.i
just want to know dose such code is still valid now?
