db_test tutorial example - table selection does not work

[WolfgangFahl]

https://justpy.io/grids_tutorial/database/ is now available in the examples/tutorial directory and automatically downloads the database as outlined in #466. The first table is shown but the selection does not work:

The /city route works

I think I see the problem. The caching mechanism for ag-grid and is probably causing this issue. I'll work on this.

This is what the javascript debugger says:

 evaluate_formatters(def) {
            if (Array.isArray(def)) {
                for (const element of def) {
                    this.evaluate_formatters(element);
                }
            } else if (typeof def == "object" && def !== null) {
                for (const [key, value] of Object.entries(def)) {
                    if (key.toLowerCase().includes('formatter')) {
                        eval('def[key] = ' + def[key]);
                    }
                    this.evaluate_formatters(value);
                }
            }
        },

there is a cut&paste copy version of this in chartjp.js

Yes, and it does not work for ag-grid. At this stage I recommend removing or commenting out line https://github.com/justpy-org/justpy/blob/master/justpy/templates/js/aggrid.js#L35 until we can revisit this. The example will work then.
