Issue when using Model based tabulator

[theref]

I'm trying to pass in a list of objects, rather than dicts, to self.tabulator.data. My tabulator config looks like:

self.tabulator.options = {
            "selectable": "highlight",
            "index": "uuid", # or set the index property here
            "use_model": True,
            "getter": "getattr",
        }
        self.tabulator.columns = [
            {"title": "ISIN", "field": "isin"},
            {"title": "SEDOL", "field": "sedol"},
            {"title": "Bloomberg", "field": "bloomberg_code"},
            {"title": "Market Status", "field": "market_status"},

and I can see that self.tabulator.data is set to: [<app.model._instrument.Instrument object>], a list containing one of my own objects.

I'm getting the error:

@s-cork Have you seen this before?

The getter should be a function.

just using getattr rather than "getattr" is probably what you want.

Immediately worked! Thank you so much
