Hi everyone :-) I'm currently writing a small app that should store data for registered users and guests alike in one single model. So I made following model (simplied)
class Content(models.Model): user = models.ForeignKey(User, null=True, blank=True) The problem I now face is, that Django seems not to do a LEFT OUTER JOIN when fetching all the instances of this model when queried with select_related(), which naturally results in a huge amount of queries (I guess on query per NOT NULL foreign key). My question now is, what options do I have to keep the query count low? So far I think I have following ones: (1) Query without selected related and then fill the content.user fields manually with a seperate WHERE IN query for the user.ids (2) Use something like Martin Fowler's NULL Object pattern and basically create a user with the ID 0 (or a negative integer if possible) Thank you :-) - Horst --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
