But I have realized that select_related in one of my models doesn't preload all the ForeignKeys and OneToOneFields, it preloads 3 out of 5. Actually the 3 preloaded are ForeignKeys and the other 2 are OneToOneFields. Before trying to reproduce this problem in a simplified schema, I need someone to confirm this is unusual.If I do a select_related('names', 'of', 'the', 'five', 'fks') everything is loaded. Last thing I can say is that those OneToOneFields point models that reference back to model pointing at them, for performance reasons. I reckon this can be a bug.Thanks, best regards----Miguel Araujo@maraujopIt would have helped if you'd posted your model. If your relationships are defined as null=True, then select_related() doesn't follow them unless you specify them explicitly.--DR.--
