Question

我正在为用于Cordova应用程序的Web SQL存储创建一个适配器。到目前为止，除了由于某种原因完全没有调用deleteRecord方法之外，它还是相当不错的。这是我的代码的摘录：

DS.CordovaStorageAdapter = DS.Adapter.extend({
  // Other methods...
  deleteRecord: function(store, type, record) {
    console.info('Deleting!');
    var adapter = this;
    var qr = new QueryRapper({id: record.get('id')}).tableName(this.tableName(type));
    var query = qr.deleteQuery();
    console.info(query);
    function deleteSuccess(tx, results) {
      adapter.didDeleteRecord(store,type,record);
    }
    return this.db.transaction(
      function(tx) { tx.executeSql(query, [], deleteSuccess); },
      function(err) { this.dbError(query, err, type, record); }
    );
  },  
  // Support methods...
});

这是我的茉莉花测试：

describe('EmberCordovaStorageAdapter', function() {
  var m;

  beforeEach(function() {
    waitForDbInit();
    runs(function() {
      m = App.TestModel.createRecord({
        string: 'String!',
        number: 1234,
        date: new Date(),
        boolean: true
      });
      m.save();
      waitForReady();
    });
  });

  // Other tests...

  it('deletes a record', function() {
    waitForReady();
    runs(function() { console.info('Deleting in test!'); m.deleteRecord(); waitForDeleted(); });
    runs(function() { expect(m.get('isDeleted')).toBe(true); });
  });

  function waitForDeleted(model) {
    model = model || m;
    waitForMessage(model, 'rootState.deleted.committed');
  }

  function waitForReady(model) {
    model = model || m;
    waitForMessage(model, 'rootState.loaded.saved');
  }

  function waitForMessage(model, msg) {
    waitsFor(function() {
      console.info(msg, model.get('stateManager.currentPath'));
      return model.get('stateManager.currentPath') == msg;
    }, 'model message: ' + msg, 1500);
  }
});

我在JS控制台中看到消息“正在测试中删除！”但不是“删除！”的消息。 github repo可以在这里找到：https://github.com/eltiare/ember-cordova-storage

我没有编写自定义适配器的经验，但是快速浏览一下您的测试我看到您的来电deleteRecord，但我没有看到对commit的调用

为了让ember-data真正尝试删除你需要调用commit的记录。要提交defaultTransaction，您可以执行以下操作：

m.get('store').commit();

deleteRecord没有在ember-data中调用
