Thanks again. The tips are really appreciated.
I added the hobo_reorder as shown below. The page now renders properly
(with the sortable-collection UI controls).
class UnitsController < ApplicationController
hobo_model_controller
auto_actions :all
def reorder
hobo_reorder
end
end
The page now renders properly (with the sortable-collection UI
controls), but moving a list item fails to update the position with
the following error:
ActiveRecord::UnknownAttributeError (unknown attribute: position):
I have the position declared on the join relation:
has_many :unit_activities, :order => :position
Is this the right place, or is there something else I need to tweak to
get this going?
I'm getting closer...
