ProgrammingError : PostgreSQL backend : missing a cast to handle inet with the ILIKE operator

Reported by: guillaume.pratte@… Owned by: Adrian Holovaty
Component: Database layer (models, ORM) Version: dev
Severity: major Keywords:
Cc: Triage Stage: Unreviewed
Has patch: no Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: no UI/UX: no


Django SVN version and PostgreSQL 8.0

How to reproduce :

  1. Define the following model :
class Session(models.Model):
    username = models.CharField(maxlength = 30)
    ip = models.IPAddressField()
    class Meta:
        unique_together = (("username", "ip"),)
  1. Go in the admin interface
  1. Add a new row for Sessions

It will fail :

  ProgrammingError at /admin/traffaccount/session/add/
  ERROR: operator does not exist: inet ~~* "unknown" HINT: No operator matches the given name and argument type(s). You may need to add explicit type casts. SELECT "traffaccount_session"."id","traffaccount_session"."username","traffaccount_session"."ip","traffaccount_session"."begin_tmst","traffaccount_session"."end_tmst","traffaccount_session"."in_octets","traffaccount_session"."out_octets","traffaccount_session"."in_delta","traffaccount_session"."out_delta" FROM "traffaccount_session" WHERE ("traffaccount_session"."username" ILIKE 'user' AND "traffaccount_session"."ip" ILIKE '')

I tried this manual SQL to debug:

select * from traffaccount_session where ip ilike cast('' as inet);
ERROR:  operator does not exist: inet ~~* inet
HINT:  No operator matches the given name and argument type(s). You may need to add explicit type casts.

The correct way seems to be:

select * from traffaccount_session where cast(ip as char(15)) ilike '';
