How to retrieve Ruby instance by ID from QML root JSObject?

[coezbek]

Is there an easy way to get the Ruby object instance from a loaded qml file?

For instance how can we get the FizzBuzz instance that is created from Fizzbuzz.qml?

We might be able to use something like this:

QML.application.root.to_hash["data"].to_hash["0"].unwrap

But this would require some guess-work, because it depends on the order of components under the root object.

Is there away use findChild as would be the solution when using C++?

Could you add an example to the docs?

(btw: is there a way to get root.to_hash["data"] to return an array rather than a hash?)
