Most likely the foreign keys are defined as "deferrable initially deferred", meaning that the database doesn't check them before commit. And this of course means that Django can't catch the error before commit. >From the error message it seems like you are using Postgres, you can check if this is the case by running manage.py dbshell and then type "\d traffic_tracking2010". From the output you should see the deferrable initially deferred on the foreign key. You could manually disable the deferred behavior, but I don't know what this breaks. Probably something, as there must be some reason for Django using deferred checking. -- Anssi -- You received this message because you are subscribed to the Google Groups "Django users" group.
