How to get `parentKey` to add new node

Hi, First of all I really like your implemented stuff, it saves my lot of time. So thanks for implementing this sortable tree, but it would be more better if you can make the documentation more descriptive. Because I am having issue while using the Data Helper Functions. I am trying to use the addNodeUnderParent(treeData, newNode, parentKey) but dont know how to get the parentKey.

Also I did not the use of getNodeKey parameter, so can you please explain these thing with some example.

Actually I am pretty new for React. So please help me to get out of it.

@fritz-c can you please look into it.

Thanks

try this code:

    addNode(rowInfo){
        let NEW_NODE = {title: 'Another Node', subtitle: 2};
        let {node, treeIndex, path} = rowInfo;
        path.pop();
        let parentNode = getNodeAtPath({
            treeData: this.state.treeData,
            path : path,
            getNodeKey: ({ treeIndex }) =>  treeIndex,
            ignoreCollapsed : true
        });
        let getNodeKey = ({ node: object, treeIndex: number }) => {
            return number;
        };
        let parentKey = getNodeKey(parentNode);
        if(parentKey == -1) {
            parentKey = null;
        }
        let newTree = addNodeUnderParent({
                treeData: this.state.treeData,
                newNode: NEW_NODE,
                expandParent: true,
                parentKey: parentKey,
                getNodeKey: ({ treeIndex }) =>  treeIndex
         });
         this.setState({treeData: newTree.treeData});
    }

It’s works fine for me.

@everyonesdesign Thanks for taking the time to explain. I do have another question - if you need to get the parent of the node, why don’t you use the path? If your path = [2,3,1], then the parent should be treeData[2].children[3] ?

Edit: i guess what i posted above is true, but that info doesn’t necessarily make finding the parent easier. I ended up using a slightly modified version of your function. Thanks for the help!
