Modifying the identifier of a node is not working properly

[ghost]

Hello,

tree = Tree()
tree.create_node("Harry", "harry")
tree.create_node("Jane", "jane", parent="harry")
n= tree.get_node("jane")
n.identifier=("xyz")

tree.get_node("xyz") ### returns None 
tree.get_node("jane") ### return a Node object whose identifier is "xyz" ! 

Hope you can address this,

Thnaks.

The Tree class maintains a internal _nodes dictionary which is not updated on identifier and other changes.

You may want to use a reimplementation of treelib called anytree

from anytree import Node
from anytree import find_by_attr


root = Node('harry')
Node('jane', parent=root)
n = find_by_attr(root, 'jane')
n.name = 'xyz'

find_by_attr(root, 'xyz')  ### returns     Node('/harry/xyz')
find_by_attr(root, 'jane')  ### returns None

HTH

Perfect, used anytree and it is solved now. many thanks.

Now treelib supports node attribute modification:

Update non-root node

from treelib import Tree, Node
tree = Tree()
tree.create_node("Harry", "harry")
tree.create_node("Jane", "jane", parent="harry")

tree.update_node("jane", identifier='xyz')
assert tree["xyz"].identifier == 'xyz'

Update root node

from treelib import Tree, Node
tree = Tree()
tree.create_node("Harry", "harry")
tree.create_node("Jane", "jane", parent="harry")

tree.update_node("harry", identifier='xyz')
assert tree.root == 'xyz'
assert tree['jane'].bpointer == 'xyz'
