Hi, This topic has been discussed before here: http://groups.google.com/group/django-users/browse_thread/thread/fcd04f766b101a95/b65b70aa6b03729e?lnk=gst&q=unique_together%2C+null#
Don't you agree that two field combinations like ("A", null) and ("A", null) should be considered identical and hence should be blocked from being entered into the database when "unique_together" condition is imposed on that field combination? Right now Django does not think so and will let both of those two records get into the database, which is really puzzling to me. Any rationale for such a counter-intuitive (to me) behavior? Thank you for shedding your light on it. Wanrong --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
