javascript – 如何在ember.js中的组件中获取商店

我是如何在一个组件内部处理商店的？我正在尝试创建一个从商店返回结果的自动完成组件.

App.AutoCompleteComponent = Ember.Component.extend({

    //-------------------------------------------
    // Ember Properites
    //-------------------------------------------
    content: Ember.ArrayController.create(),//-------------------------------------------
    // Instance Properties
    //-------------------------------------------
    queryText: "",componentItemSelected: null,//-------------------------------------------
    // Observers
    //-------------------------------------------
    queryTextChanged: function () {
        this.updateContent(this.get("queryText"));
    }.observes("queryText"),//-------------------------------------------
    // Instance Methods
    //-------------------------------------------
    selectItem: function (item) {
        this.set("componentItemSelected",item);
    },updateContent: function (queryText) {

        if (queryText.length <= 5) {

            console.log('not greater than 5 chars');
            return;
        }

        this.get("content").setobjects([]);

        var items = App.Company.find();

        this.get("content").setobjects(items);
    }
});

这是我公司的模特

App.Company = DS.Model.extend({

  name: DS.attr('string'),created_at: DS.attr('date'),updated_at: DS.attr('date'),people: DS.hasMany('person')

});

我试过了：

> this.get(‘store’)
> DS.Store.find(‘company’)
>只是存储
> App.Company.find()

我总是得到一个Uncaught TypeError …没有方法’find’

解决方法

真正的答案是你不应该.组件应该与外部世界无关,并且在商店中添加依赖项会破坏该概念.实际上你应该事先得到模型(在路线或控制器中,取决于逻辑)并将它们传递到组件中.

https://github.com/emberjs/data/blob/master/TRANSITION.md

In general,looking up models directly in a component is an anti-pattern,and you should prefer to pass in any model you need in the template that included the component.

现在我已经说过了,只需将商店传递给组件即可.它存在于路由和控制器上,因此当您在商店中创建组件作为参数之一发送时,您可以使用this.get(‘store’)访问它

{{auto-complete store=controller.store}}

要么

{{auto-complete store=store}}
