JSON.parse not compiling to a Tree::TreeNode

[westlakem]

Title says it all, JSON.parse is returning the default hash instead of tree

json file

{
  "name": "ROOT",
  "content": null,
  "json_class": "Tree::TreeNode",
  "children": [
    {
      "name": "NON-ROOT",
      "content": null,
      "json_class": "Tree::TreeNode",
      "children": [
        {
          "name": "NON-ROOT-2",
          "content": null,
          "json_class": "Tree::TreeNode"
        }
      ]
    }
  ]
}

r = JSON.parse(File.read('config/routes.json'))

=> {"name"=>"ROOT", "content"=>nil, "json_class"=>"Tree::TreeNode", "children"=>[{"name"=>"NON-ROOT", "content"=>nil, "json_class"=>"Tree::TreeNode", "children"=>[{"name"=>"NON-ROOT-2", "content"=>nil, "json_class"=>"Tree::TreeNode"}]}]}

r.class

=> Hash

@evolve75 Any updates?

I am using this as a workaround:

def load_tree(json_hash)
  node = Tree::TreeNode.new(json_hash['name'], json_hash['content'])
  json_hash['children'].each { |h| node << load_tree(h) } unless json_hash['children'].nil?
  node
end

I guess the performance is terrible but it's working well enough for me with a tree < 10,000 leafs.

The core behavior in Ruby seems to have changed, use create_additions option on JSON.parse

      JSON.parse(str, create_additions: true)
