Instance Method Details

#ancestors(start = []) ⇒ Object

Return the list of ancestors (without self): [root, obj, obj] ancestors to which the visitor has no access are removed from the list

    [current_site.root_node].compact + (secure(Node) { Node.fullpath_map(path, :node) } || [])
  end
end

#basepath ⇒ Object

url base path. If a node is in ‘projects’ and projects has custom_base set, the node’s basepath becomes ‘projects’, so the url will be ‘projects/node34.html’. The basepath is cached. If rebuild is set to true, the cache is updated.

end

#fullpath_as_title(path = fullpath) ⇒ Object

(slow). Transform a list of zips into a fullpath.

  else

#is_ancestor?(child) ⇒ Boolean

Return true if the current node is an ancestor for the given child

Returns:
