#35077: Quering with int that has bigint in database no longer working. -------------------------------------+------------------------------------- Reporter: Matej | Owner: nobody Spiller Muys | Type: Bug | Status: new Component: Database | Version: 5.0 layer (models, ORM) | Severity: Normal | Keywords: regression Triage Stage: | Has patch: 0 Unreviewed | Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | -------------------------------------+------------------------------------- If you have table with bigint column in DB but field is defined as int (implicit auto field) it no longer selects the value from the database. It silently returns 0 records without any warning. In 4.2 it returned all the records regardless of defined type. Database that is used is mysql 8.
{{{ class BalanceSessionStatus(models.Model): class Meta(object): db_table = 'market_balancesession_status' app_label = 'market' default_permissions = ('add',) status = models.PositiveSmallIntegerField(null=False) created_at = models.DateTimeField(null=False, auto_now=True) insert_id = 5 # insert_id = 1477468537765888 market_models.BalanceSessionStatus( id=insert_id, status=0, ).save() assert market_models.BalanceSessionStatus.objects.filter(id=insert_id).exists() }}} Table is created with: {{{ CREATE TABLE `market_balancesession_status` ( `id` bigint NOT NULL, `status` tinyint NOT NULL, `created_at` datetime(6) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3 COLLATE=utf8mb3_unicode_ci; }}} It works with id = 5 but fails with 1477468537765888.

I understand that there is minor inconsistency between model and DB ... However django shouldn't silently not select the value but should emit a warning or error if value is invalid. -- Ticket URL: <https://code.djangoproject.com/ticket/35077> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
