Is there anyway to add a filter / scope to only display results in in =
the list view for a has_many association?  It currently gives me =
"undefined method `searchable_columns' for nil:NilClass " if I add :tags =
as a filters [:tags]

My Post has_many :tags :through =3D> :taggings and  I really need the =
ability to allow my users to choose a tag from a drop down and sort that =
way.  Is it possible?


Sincerely,
