Scope

Display / Proc.

This works like foreign_sortby, but in case of using bidirectional symmetric relations. Each side of a symmetric relation could have its own sorting, so symmetric_sortby defines a field on the foreign_table where the sorting of the "other" side is stored. This property requires that the foreign_field approach is used.
