no issue - replace logic for preparing nested tags - if you have nested tags in your file, we won't update or update the target tag - we simply would like to add the relationship to the database - use same approach as base class - add `posts_tags` to target post model - update identifiers - insert relation by foreign key `tag_id` - bump bookshelf-relations to 0.1.10
