Description
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
