I have a query where it looks like Django 1.3 is generating incorrect sql. It involves these four models.
class Aaa(models.Model): pass class Bbb(models.Model): aaa = models.ForeignKey(Aaa, related_name='bbbs') class Ccc(models.Model): bbb = models.ForeignKey(Bbb, related_name='cccs') class Ddd(models.Model): aaa = models.ForeignKey(Aaa, related_name='ddds') passed = models.BooleanField() So here's the query; I expect it to give me the number of cccs that are not attached to a non-passed ddd. I [1]: Ccc.objects.exclude(bbb__aaa__ddds__passed=False).count() Here's the sql generated by django, from connection.queries: SELECT COUNT(*) FROM "myapp_ccc" INNER JOIN "myapp_bbb" ON ("myapp_ccc"."bbb_id" = "myapp_bbb"."id") WHERE NOT (("myapp_bbb"."aaa_id" IN (SELECT U1."id" FROM "myapp_bbb" U1 INNER JOIN "myapp_aaa" U2 ON (U1."aaa_id" = U2."id") INNER JOIN "myapp_ddd" U3 ON (U2."id" = U3."aaa_id") WHERE U3."passed" = false ) AND "myapp_bbb"."aaa_id" IS NOT NULL)) It looks like the inner select statement returns a list of bbb ID's, but the WHERE NOT condition asks if a aaa id is in the list of bbb ID's, which doesn't make any sense. Basically, it should say: WHERE NOT (("myapp_bbb"."id" IN (SELECT U1."id".... What do you think?
