遵守組件

Question

灰燼數據存儲的變化我有一個特定的模式這樣造成記錄組件：

export default Ember.Component.extend({ 

    store: Ember.inject.service(), 

    addRecord(account) { 
     this.get('store').createRecord('update', { 
     authUid: account.get('authUid'), 
     service: account.get('platform') 
     }); 
    } 
}); 

我有一個需要觀察做一個特定的模式變化的另一個組件（即，如果記錄添加或刪除），並在該組件中顯示它們。

export default Ember.Component.extend({ 
    store: Ember.inject.service(), 

    observeStoreChanges: /*What should I write so that every time `addRecord` 
pushes record in the store, a function is executed in this component*/ 

}); 

Answer 1

如果你是觀察者模式的粉絲：

// store.js 
export default DS.Store.extend(Ember.Evented, { 
    createRecord() { 
     const record = this._super.apply(this, arguments); 
     this.trigger('recordCreated', record); 
     return record; 
    } 
}); 

// component.js 
export default Ember.Component.extend({ 
    observesStoreChanges: function(record) { 

    }.on('store.recordCreated') 
});
