Server model relation:
{{{ server_model = models.ForeignKey('ServerModel', blank=True,
null=True) }}}
{{{
a = System.objects.all()[0]
b = ServerModels.objects.all()[0]
b.delete()
}}}
Both b and a are deleted.
db.connection.queries:
{{{
{'sql': u'SELECT `systems`.`id`, `systems`.`hostname`,
`systems`.`serial`, `systems`.`operating_system_id`,
`systems`.`server_model_id`, `systems`.`created_on`,
`systems`.`updated_on`, `systems`.`oob_ip`, `systems`.`asset_tag`,
`systems`.`notes`, `systems`.`licenses`, `systems`.`allocation_id`,
`systems`.`system_rack_id`, `systems`.`rack_order`,
`systems`.`switch_ports`, `systems`.`patch_panel_port`,
`systems`.`oob_switch_port`, `systems`.`purchase_date`,
`systems`.`purchase_price`, `systems`.`system_status_id`,
`systems`.`change_password`, `systems`.`ram` FROM `systems` WHERE
`systems`.`server_model_id` = 221 ',
{'sql': u'UPDATE `systems` SET `server_model_id` = NULL WHERE `id` IN
(1333)',
{'sql': u'DELETE FROM `systems` WHERE `id` IN (1333)'},
{'sql': u'DELETE FROM `server_models` WHERE `id` IN (221)'}]
}}}
I'm not seeing this problem on 1.1, but I am seeing it on 1.1.1 and later.
