If you have a Rails application where ParentModel has many MiddleModel
's, and a MiddleModel has many ChildModel
's, you may want to look at my list_for class method, published on my blog.  Invoked in your MiddleModelsController as

  list_for :parent_model, 'some_column ASC, other_column DESC'

it will generate a list_for_parent_model method.  See the description and code.
