I think I am confused about how to use generic relations properly - when I delete something, cascading delete is not happening as expected.
Here are my models: class Permission(models.Model): name = models.CharField(maxlength=32) content_type = models.ForeignKey(ContentType, null=True) object_id = models.PositiveIntegerField(null=True) content_object = generic.GenericForeignKey() class Subject(models.Model): name = models.CharField(maxlength=32) perms = generic.GenericRelation(Permission) class Group(models.Model): name = models.CharField(maxlength=32) perms = models.ManyToManyField(Permission, null=True) (The goal is that a group can have permissions, and each permission pertains to a subject object, but the subject object can be one of many different types.) In my test scenario, I add two subjects (s1 and s2), two permissions referring to these subjects (p1->s1, p2->s2), and one group (g1) that is assigned both permissions. So far so good. When I delete the second subject (s2), things mostly happen as expected: Subject.objects.all() shows only s1 Permission.objects.all() shows only p1 g1.perms.all() shows only p1 However, the database table that contains the relationships between Group and Permission still has rows for both permissions (shown using sqlite3 and .dump): CREATE TABLE "test_group_perms" ( "id" integer NOT NULL PRIMARY KEY, "group_id" integer NOT NULL REFERENCES "test_group" ("id"), "permission_id" integer NOT NULL REFERENCES "test_permission" ("id"), UNIQUE ("group_id", "permission_id") ); INSERT INTO "test_group_perms" VALUES(1, 1, 1); INSERT INTO "test_group_perms" VALUES(2, 1, 2); CREATE INDEX "test_permission_content_type_id" ON "test_permission" ("content_type_id"); COMMIT; This seems mostly harmless, except that when I create a new subject (s3) and associate it with a new permission (p3), my group g1 now has permission p3 even though it was never explicitly assigned that permission: >>> g1.perms.all() [<Permission: p1>, <Permission: p3>] Do I need to somehow clean up the "test_group_perms" table when I delete a subject? Or am I coding my modules incorrectly? I am using the SVN version of Django trunk, updated 7/31/2007. Thanks for any help!
