Hi, I''m new in developint rails (but I love rails). I would like to react on changing a field in the view (no model field) from a selection box to show the number of rows (which I used in the controller).

So I''m trying to do a find with an order by specific column values thing, but some of the columns are attributes through associations. So I did some eager loading with the :include option to try and access the attributes of the object I''m doing the find on. Stuff has been blowing up on me so far.
