adapter

问题 Can a local storage adapter and a data storage adapter be used simultaneously? Here's some example code. VpcYeoman.ApplicationAdapter = DS.LSAdapter.extend({ namespace: 'viewpoint-emberjs' }); vs. VpcYeoman.Store = DS.Store.extend({ revision: 12, adapter: DS.FixtureAdapter.extend({ queryFixtures: function(fixtures, query, type) { return fixtures.filter(function(item) { for(prop in query) { if( item[prop] != query[prop]) { return false; } } return true; }); } }) }); Fight!

问题 Let's say I have a class from a 3rd-party, which is a data-model. It has perhaps 100 properties (some with public setters and getters, others with public getters but private setters).

问题 I'm trying to add the search functionality to a ListView that has a custom adapter. When I type something in the EditText it searches and shows the results corectly but if I try to erase what I just wrote it won't come out with the initial list, it will stay with the already filtered list.
