Public Instance methods

acts_as_nested_set(options = {})

Configuration options are:

  • dependent - behaviour for cascading destroy operations (default: :delete_all)
  • parent_column - Column name for the parent/child foreign key (default: parent_id).
  • left_column - Column name for the left index (default: lft).
  • right_column - Column name for the right index (default: rgt). NOTE: Don‘t use left and right, since these are reserved database words.
  • scope - Restricts what is to be considered a tree. Given a symbol, it‘ll attach "_id" (if it isn‘t there already) and use that as the foreign key restriction. It‘s also possible to give it an entire string that is interpolated if you need a tighter scope than just a foreign key. Example: acts_as_nested_set :scope => ‘tree_id = #{tree_id} AND completed = 0‘
  • text_column - Column name for the title field (optional). Used as default in the {your-class}_options_for_select helper method. If empty, will use the first string field of your model class.
