Hi,
i got a simple example where a Model.save() that should raise
integrity/operational errors is not:
class one(models.Model):
fk_field = models.ForeignKey('two')
class two(models.Model):
description = models.CharField(maxlength=10)
In [1]: from webfi.sd.models import *
In [2]: One(fk_field_id=1)
Out[2]: <One: One object>
In [3]: One(fk_field_id=1).save()
The last line should have raised an integrity error but it does not. Db log
(PostgreSQL) shows:
STATEMENT: INSERT INTO "sd_one" ("fk_field_id") VALUES (1)
2007-06-05 16:55:38 [30666] LOG: duration: 0.345 ms statement: SELECT
CURRVAL('"sd_one_id_seq"')
STATEMENT: SELECT CURRVAL('"sd_one_id_seq"')
2007-06-05 16:55:38 [30666] ERROR: insert or update on table "sd_one" violates
foreign key constraint "$1"
DETAIL: Key (fk_field_id)=(1) is not present in table "sd_two".
a second 'save' results in:
In [4]: One(fk_field_id=1).save()
---------------------------------------------------------------------------

13 finally:
14 stop = time()
OperationalError: insert or update on table "sd_one" violates foreign key
constraint "$1"
DETAIL: Key (fk_field_id)=(1) is not present in table "sd_two".
And that's ok, but too late...
It seems to me too big a mistake so I hope I'm just missing something, if
not I'll file a new ticket for this. I think in no way a db error should be
ignored...
I tried with a fresh svn co of rel 5427.
Any comments?
