[SOLVED] Grouping WSAPI data store by Parent Name

Grouping WSAPI data store by Parent Name

I am creating a rallygrid component and would like to have the grid items grouped by their parent's Name attribute (bonus if I could also display the ID of the parent). I added the groupBy:'Parent' configuration to the storeConfig of the grid and was surprised that no results were returned. I also tried using groupBy:'Parent.Name' but still nothing.

I know this is possible with other fields such as Owner, but I'm at a loss as to why the Parent wouldn't be usable as well. Is this a bug, or am I setting the config up incorrectly?

Thanks

Solution

Change the storeConfig to keep the records from trying to update after being grouped:

storeConfig : {
    remoteSort   : false,
    remoteGroup  : false,
    remoteFilter : false,
}

Add a listener to the load event which assigns a root level property to the record and groups by that record value. (For some reason store.group('Parent.Name'); doesn't work.)

load: function(store) {
    store.each(function(record) {
        record.set('ParentName', record.get('Parent') && record.get('Parent').Name || '-- Unparented --');
    });

    store.group('ParentName');
}
