Hi Chris, I suppose you have all the breweries' data in a DB table referenced by breweryInfoModel and need to extract data by locid. In this case you could wrap your breweryInfoModel in a QSortFilterProxyModel [1] and just use its filtering methods. In this case you would basically need to set your breweryInfoModel as a source model for QSortFilterProxyModel, it does all the rest for you.
If you feel that QSortFilterProxyModel is not what you need, it could help then if you would go into details of your DB model.
