How to do this? i've extended the userfield model and datawriter, added it to the enum field in the database, but what's the best way to put this into an addon? e.g. i can't just use this query Code: ALTER TABLE `xf_user_field` CHANGE `display_group` `display_group` ENUM ( 'personal', 'contact', 'preferences', 'test1', 'test2' ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL DEFAULT 'personal'; because it would add test1 and test2 but remove e.g. all other custom enum values.
