q-tree: Is there a getParentNode() method?

[murrah]

Each node in my tree has a unique nodeid property and node-key="nodeid".

With a set of ticked nodes, I also need to get their parents. getNodeByKey() and getTickedNodes() return node objects but it seems I cannot do:

const aNode = this.$refs.myTree.getNodeByKey(nodeid)
const parentNode = aNode.getParent()

Instead I have made my own method:

    getParentNode (nodeid) {
      const nodeMeta = this.$refs.myTree.meta[nodeid]
      const parentNode = this.$refs.myTree.getNodeByKey(nodeMeta.parent.key)
      return parentNode
    }

Am I missing something or is that the way to do it?
Thanks,
Murray

A more robust version:

    getParentNode (nodeid) {
      let parentNode = null
      if (nodeid) {
        const nodeMeta = this.$refs.projectTree.meta[nodeid]
        if (nodeMeta.parent) {
          parentNode = this.$refs.projectTree.getNodeByKey(nodeMeta.parent.key)
        }
      }
      return parentNode
    }

@murrah I use a recursive function for this, my node structure is unlimited nesting. i use scope-slots ie.

// node model
[{
  id: 1, // unique id
  name: '',
  description: '',
  children: [], // same array of objects like this node
  parent_id: null, // null indicates this node is root, else holds id of its immediate parent
  ... // other props
}]

getRootNode (tree, node) {
      let curNode = node.parent_id !== null ? tree.getNodeByKey(node.parent_id) : node
      if (curNode.parent_id !== null) {
        curNode = this.getRootNode(tree, curNode)
      }
      return curNode
    }
