I have two models:
{{{
class Info(models.Model):
name = models.CharField(verbose_name='name', max_length=128)
class Meta:
verbose_name = verbose_name_plural = "name"
class Version(models.Model):
id = None
info = models.ForeignKey(Info, on_delete=models.DO_NOTHING,
db_constraint=False)
version = models.CharField(verbose_name='version number',
max_length=128)
class Meta:
unique_together = ('version', 'info')
verbose_name = verbose_name_plural = "name"
}}}
I want to add mysql PARTITION to version.
PARTITION KEY must be included by all unique indexes.
so I want to remove id like
{{{
CREATE TABLE `version` (
`version` varchar(128) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci
NOT NULL,
`package_id` bigint NOT NULL,
UNIQUE KEY `version_version_package_id_fc0eb1b8_uniq`
(`version`,`package_id`),
KEY `version_package_id_2d2bab67` (`package_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci
/*!50100 PARTITION BY KEY (package_id)
PARTITIONS 32 */
}}}
How can I modify models to meet my needs
