Join Tables Scuttle doesn't know anything about your Rails models, so it can't correctly identify join tables (i.e. tables that have no corresponding Ruby class). You'll need to replace these by hand. Usually this can be resolved by creating an Arel::Table object and referencing its columns. For example, create a table: pc = Arel::Table.new("posts_comments"), then use it like so: pc[:post_id]. Qua
