ember.js - Ember model find records without server request -

i have ember model category:

export default ds.model.extend({   name: ds.attr('string'),   img: ds.attr('string'),   url: ds.attr('string'),   cnt: ds.attr('number'),  //  parent_id: ds.belongsto('category', { //    inverse: 'children', //    async: true //  }),   parent_id: ds.attr('string'),  //  children: ds.hasmany('category', { //    inverse: 'parent_id', //    async: true //  }),   children: ds.attr(),    isselected: false,   isexpanded: false,    haschildren: function() {     return this.get('children').get('length') > 0;   }.property('children').cacheable(),    isleaf: function() {     return this.get('children').get('length') == 0;   }.property('children').cacheable() }); 

in index route have:

export default ember.route.extend({   model: function() {     var store = this.store;     return ember.arrayproxy.create({       categories: store.find('category'),       menutopcategories: store.find('category', { parent_id: 1 })     });   } }); 

i'm using restadapter store.find send 2 requests server: categories , categories?parent_id=1. have first request , filter through categories. tried store.all - since saw reuses fetch data, can't manage apply filter.

i've rewritten menutopcategories , don't see new request:

menutopcategories: store.filter('category', function(category) {    return category.get('parent_id') === "1"; }) 

my problem right root category (first one) without hardcoding parent_id.
