Migrations should never use model structs directly, because the model structs can be different in different releases. e.g. if one migration uses "User" model, it works in the early releases, then one day, when the User model changes, the migration breaks because it will use the new (incorrect) User model, it should only use the old User model. The same to "modules/structs". --------- Signed-off-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: delvh <dev.lh@web.de>
