Question

我正在尝试使用ember-chart用Ember设置简单的应用程序： https://www.npmjs.com/package/ember-cli-chart

我有我的chart.hbs文件：

<div class="container-fluid">
    <div class="row">
        <div class="col-md-12">
        {{#toggle-section}}
            <div class="chart-container">
                {{ember-chart type=CHARTTYPE data=CHARTDATA options=CHARTOPTIONS width=CHARTWIDTH height=CHARTHEIGHT}}
            </div>
        {{/toggle-section}}
        </div>
    </div>
</div>

和我的Charts.js控制器，以及Chart.js文档中的示例：

import Controller from '@ember/controller';
import Ember from "ember";

export default Controller.extend({
    CHARTTYPE: 'bar',
    CHARTDATA: Ember.Computed('', function () {
        return {
            labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
            datasets: [{
                label: '# of Votes',
                data: [12, 19, 3, 5, 2, 3],
                backgroundColor: [
                    'rgba(255, 99, 132, 0.2)',
                    'rgba(54, 162, 235, 0.2)',
                    'rgba(255, 206, 86, 0.2)',
                    'rgba(75, 192, 192, 0.2)',
                    'rgba(153, 102, 255, 0.2)',
                    'rgba(255, 159, 64, 0.2)'
                ],
                borderColor: [
                    'rgba(255,99,132,1)',
                    'rgba(54, 162, 235, 1)',
                    'rgba(255, 206, 86, 1)',
                    'rgba(75, 192, 192, 1)',
                    'rgba(153, 102, 255, 1)',
                    'rgba(255, 159, 64, 1)'
                ],
                borderWidth: 1
            }]
        }
    }),
    CHARTOPTIONS: Ember.Computed('', function () {
        return {
            scales: {
                yAxes: [{
                    ticks: {
                        beginAtZero:true
                    }
                }]
            }
        }
    }),
    CHARTWIDTH: 500,
    CHARTHEIGHT: 500,
});

在index.js路由中，我已重定向到图表路由：

beforeModel() {
    this.replaceWith('charts');
}

当我尝试在localhost:4200之后打开ember s时，控制台出现错误：

router.js:927 Error while processing route: index Ember.Computed is not a function TypeError: Ember.Computed is not a function

我试图寻找答案，但似乎无济于事。

Answer 1

该函数为小写字母：Ember.computed

最好使用此导入：

import { computed } from '@ember/object';

避免仅为了访问计算函数而引入所有Ember框架。

Ember.Computed不是函数
