#default_roots_collection ⇒ Object

Find the roots by calling the roots method directly on the resource. This effectively performs:

TreeNode.roots # => [#<TreeNode id:1>, ... ]

Returns collection of roots.

def roots
  roots_collection || default_roots_collection
end

#roots_collection ⇒ Object

Use user-defined logic to find the root nodes. This executes a callable object within the context of the resource’s controller.

Example

options[:roots_collection] = proc { current_user.tree_nodes.roots }

Returns collection of roots.
