Hi, I have two models like these:
class Allarme(models.Model): .... class Registrazione(models.Model): allarme = models.ForeignKey(Allarme, blank=True, null=True, on_delete=models.DO_NOTHING, db_constraint=False) .... now I want to change id field for these models from int to bigint so I added to both id = models.BigAutoField(primary_key=True) and I did the migration, python manage.py sqlmigrate show something like this: BEGIN; -- -- Alter field id on allarme -- ALTER TABLE "multimedia_allarmi" ALTER COLUMN "id" TYPE bigint USING "id"::bigint; DROP SEQUENCE IF EXISTS "multimedia_allarmi_id_seq" CASCADE; CREATE SEQUENCE "multimedia_allarmi_id_seq"; ALTER TABLE "multimedia_allarmi" ALTER COLUMN "id" SET DEFAULT nextval('"multimedia_allarmi_id_seq"'); SELECT setval('"multimedia_allarmi_id_seq"', MAX("id")) FROM "multimedia_allarmi"; ALTER TABLE "multimedia_registrazioni" ALTER COLUMN "allarme_id" TYPE bigint USING "allarme_id"::bigint; *ALTER TABLE "multimedia_registrazioni" ADD CONSTRAINT "multimedia_registrazioni_allarme_id_4919213e_fk" FOREIGN KEY ("allarme_id") REFERENCES "multimedia_allarmi" ("id") DEFERRABLE INITIALLY DEFERRED;* -- -- Alter field id on registrazione -- ALTER TABLE "multimedia_registrazioni" ALTER COLUMN "id" TYPE bigint USING "id"::bigint; DROP SEQUENCE IF EXISTS "multimedia_registrazioni_id_seq" CASCADE; CREATE SEQUENCE "multimedia_registrazioni_id_seq"; ALTER TABLE "multimedia_registrazioni" ALTER COLUMN "id" SET DEFAULT nextval('"multimedia_registrazioni_id_seq"'); SELECT setval('"multimedia_registrazioni_id_seq"', MAX("id")) FROM "multimedia_registrazioni"; COMMIT; so as you can see a foreign key is added for a model field with db_constraint=False, can you please confirm that this is a bug? I'm using django 1.11.1 thanks! -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
