You may have come to this on your own, but I was curious, so i ran a few tests. You can see my setup here: https://gist.github.com/1017306 Summary: DM doesn't correctly infer the necessary joins to enable ordering, so you have to explicitly declare the necessary links to use when ordering through an association (links are inverse relationships *back* to your source model). For example: `Author.all(:order => Author.comments.created_at.asc, :links => [Author.relationships[:comments].inverse])` This could, of course, be wrapped in a class method on Author to move the noise somewhere harmless (eg., `Author.by_comment_created_at_asc` or something).
