sorting in rails 2.3.5 not same as sorting in Rails 3

In rails 2.3.5 (with active scaffold) all my columns in display were
sorted even though they belonged to a related table. But in Rails 3.2.8
, only columns which belong to the main table are sorted .To sort a
related table column we need to specifically add the line below

columns[:typefromtable2].sort_by :sql => ['name']

I have many columns which are 'related' , it would be tedious to add
this line in them all
