找到模型后,如何添加其他模型属性? (或者如何在setupController中访问路径的参数?

给出路​​线

   this.resource('gallery', { path:'/gallery/:gallery_id' });

和路由器/routes/gallery.js

export default Ember.Route.extend({
    model: function(params) {
        return this.store.find('monkeys', { monkeyType: params.gallery_id });
        //can I add an additional property to the returned model here?
    },

    setupController: function(controller, model) {
        var pageTitle = 'something related to params.gallery_id';
        //can I access route params in here?
        this.controllerFor("application").set('pageTitle', pageTitle);
        controller.set('model', model);
    }
});

理想情况下,我想将应用程序控制器上的pageTitle属性设置为某个gallery_id特定字符串,而api服务不会返回该字符串。

api根据网址/monkeys?monkeyType=someId

返回以下内容
{ "monkeys":[{ ... }, { ... }] }

也许是这样的?

export default Em.Route.extend({
    model: function(params) {
        var model = this.store.find('monkeys', { monkeyType; params.gallery_id });

        model.then(function(models) {
            this.controllerFor('application').set('pageTitle', models.get('firstObject.name'));
        }.bind(this));

        return model;
    }
});

确保您返回model then来电返回的承诺。 store.find()会返回PromiseArray,而then()只会返回一个承诺。

以下是我最终的结果:

export default Ember.Route.extend({
    model: function(params) {
        return return {
            tag:params.gallery_id,
            monkeys:[]
        };
    },
    setupController: function(controller, model) {
        var url = window.ENV.api + 'monkeys?monkeyType=' + model.tag;

        if(model.monkeys.length === 0){
            $.getJSON(url, function(json){
                model.monkeys.pushObjects(json.monkeys);
            });
        }

        this.controllerFor("application").set('pageTitle',
             this.getTitle(model.tag));

        controller.set('model', model);
    },
    getTitle: function(tag){
        //some arbitrary non-api lookup
    }
});

我不太热衷于这个解决方案,所以很高兴听到改进,或者可能是使用Ember Data的版本。
