Question

I am fetching some records, and using the filter property as shown below;

store = Ext.getStore('PEOPLE');
store.on('load', function() {
    store.filter({
        filterFn: function(f) {
            return f.get('Name') == "SAM"; 
        }
    });
});
store .load();

The above code, will filter all Names that has the name SAM. But, what i want it to ONLY return 1 name (just only SAM (Once)).

For example, in databases we use the keyword DISTINCT to get just 1 record (if there are multiples). How can i do this in my scenario ?

Is this perhaps what you’re looking for?

store = Ext.getStore('PEOPLE');
store.on('load', function() {
    store.filter({
        filterFn: function(f) {
            return f.get('Name') == "SAM"; 
        }
    });
    if(store.getTotalCount() > 1)
        store.remove(store.getRange(1));
});
store.load();
