javascript - Ember 路由混合模型

Question

我正在使用 ember cli 生成我的项目结构。当我使用 Mixin 和模型扩展 Route 类时。这些模型不再显示在我的商店中。

controllers/application.js::(ActiveclasscontrollerMixin 只是用来提供应用程序级别的属性，用于确定哪个类属性是事件的 - 我提供这个只是为了引用它其他的 mixin ActiveclassrouteMixin.js 与路由的模型 Hook 一起使用时会导致问题。)

import Ember from 'ember';
import ActiveclasscontrollerMixin from 'embercliapp/mixins/activeclasscontroller';

export default Ember.Controller.extend(ActiveclasscontrollerMixin);

controllers/posts.js

import Ember from 'ember';
var PostsController = Ember.ArrayController.extend();
export default PostsController;

template/posts.hbs(此模板在 routes/posts.js 时工作正常，仅在扩展 Ember.Route 对象时覆盖模型并显示所有 2 个帖子)

<div class="container-fluid">
      <div class="row">
        <div class="col-md-3">
          <table class='table'>
            <thead>
              <tr><th>Recent Posts</th></tr>
            </thead>

            <tbody>
              {{#each model}}
                <tr>
                  <td>
                    {{#link-to 'post' this}}{{title}} <small class='muted'>by {{author.name}}</small>{{/link-to}}
                  </td>
                </tr>
              {{/each}}
            </tbody>
          </table>
        </div>

        <div class="span9">
          {{outlet}}
        </div>
      </div>
    </div>

mixins/ActiveclasscontrollerMixin.js -(仅在/controllers/application.js 中使用)

import Ember from 'ember';


export default Ember.Mixin.create({
    isHome: '',
    isPosts: '',
    isAbout: '',

    sayAlert: function(sayAlert){
        alert(sayAlert);
    },

    setActiveClass: function(routeName) {
        //alert('called setActiveClass:' + routeName);
        if ((routeName === 'isHome') || (routeName === 'application') || (routeName === 'index')) {
            this.set('isHome', 'active');
            this.set('isPosts', '');
            this.set('isAbout', '');
        }

        if (routeName === 'isPosts' || (routeName === 'posts')) {
            this.set('isPosts', 'active');
            this.set('isHome', '');
            this.set('isAbout', '');
        }

        if (routeName === 'isAbout' || (routeName === 'about')) {
            this.set('isAbout', 'active');
            this.set('isPosts', '');
            this.set('isHome', '');
        }

    },

    actions: {
        clickedAction: function(routeName) {
            this.setActiveClass(routeName);
        }
    }
});

mixins/ActiveclassrouteMixin.js

import Ember from 'ember';


export default Ember.Mixin.create({    

    setupController: function(controller) {
        this._super(controller);
        var routeName = this.get('routeName');
        this.controllerFor('application').setActiveClass(routeName);
      }

});

routes/posts.js

import Ember from 'ember';
import ActiveclassrouteMixin from 'embercliapp/mixins/activeclassroute';

var posts = [{
    id: '1',
    title: "Rails is Omakase",
    author: {
        name: "d2h"
    },
    date: new Date('12-27-2012'),
    excerpt: "There are lots of à la carte software environments in this world. Places where in order to eat, you must first carefully look over the menu of options to order exactly what you want.",
    body: "I want this for my ORM, I want that for my template language, and let's finish it off with this routing library. Of course, you're going to have to know what you want, and you'll rarely have your horizon expanded if you always order the same thing, but there it is. It's a very popular way of consuming software.\n\nRails is not that. Rails is omakase."
}, {
    id: '2',
    title: "The Parley Letter",
    author: {
        name: "d2h"
    },
    date: new Date('12-24-2012'),
    excerpt: "My [appearance on the Ruby Rogues podcast](http://rubyrogues.com/056-rr-david-heinemeier-hansson/) recently came up for discussion again on the private Parley mailing list.",
    body: "A long list of topics were raised and I took a time to ramble at large about all of them at once. Apologies for not taking the time to be more succinct, but at least each topic has a header so you can skip stuff you don't care about.\n\n### Maintainability\n\nIt's simply not true to say that I don't care about maintainability. I still work on the oldest Rails app in the world."
}];

export default Ember.Route.extend({
    model: function() {
        return posts;
    }
});

在上述情况下，一切都按预期进行。但是，如果我在扩展路线时添加使用混合(ActiveclassrouteMixin)和模型，模型将停止在导出中显示:

export default Ember.Route.extend(ActiveclassrouteMixin,{
    model: function() {
        return posts;
    }
});

commond cli 构建/服务过程或 chrome javascript 控制台中没有错误。

Answer 1

我会将所需的代码提炼为:

controller.js

setupController: function(controller, models) {
  this._super(controller, models); // insure mixin.setupController() called

  controller.setProperties( models );
}

---

mixin.js

setupController: function(controller, models) {
  this._super(controller, models); // Allow others to be called
}

现在您可以在 mixin 中设置模型的属性!
