【问题描述】:
我有一个包含不同课程的索引页面。从该索引页面,您可以通过链接导航到特定课程。当我导航到课程时,一切正常,但是当我刷新页面或直接转到该 URL 时,模型为空。
这就是我的代码的样子:
index.hbs ---------------------------------------
<div class="row">
<div class="col-md-6 col-md-offset-3 text-center">
<h1>Become a Tjuna Fish</h1>
<img src="http://placehold.it/500x300">
<p>Leer met de technieken werken die bij Tjuna worden gebruikt en ontwikkel jezelf tot een echte Tjuna Fish!</p>
</div>
</div>
<div class="row">
<h1 class="text-center">Cursussen</h1>
{{#each}}
<div class="col-md-4 text-center">
<div class="row">
<img {{bind-attr src="img"}}/>
</div>
<div class="row">
{{#link-to "course" this}}{{title}}{{/link-to}}
</div>
</div>
{{/each}}
</div>
scripts ---------------------------------------
BecomeTjunaFish.Router.map(function () {
// Add your routes here
this.resource('index', {path: '/'});
this.resource('course', { path: ':url'});
});
BecomeTjunaFish.IndexRoute = Ember.Route.extend({
// admittedly, this should be in IndexRoute and not in the
// top level ApplicationRoute; we're in transition... :-)
model: function () {
return this.store.find('course');
}
});
BecomeTjunaFish.CourseRoute = Ember.Route.extend({
// admittedly, this should be in IndexRoute and not in the
// top level ApplicationRoute; we're in transition... :-)
model: function (params) {
return this.store.find('course', params.id);
}
});
BecomeTjunaFish.Course = DS.Model.extend({
title: DS.attr('string'),
img: DS.attr('string'),
goal: DS.attr('string'),
targetGroup: DS.attr('string'),
prerequisites: DS.attr('string'),
url: DS.attr('string')
});
BecomeTjunaFish.Course.FIXTURES = [
{
id: 1,
title: 'Tjuna Basis',
img: 'http://placehold.it/200x200',
goal: 'kunnen werken met de basis tools en opmaaktalen die Tjuna gebruikt',
targetGroup: 'frontend developers in wording',
prerequisites: 'geen',
url: 'basis_cursus'
},
