[英]Error when rendering 2 models for a template in Ember.js
I have a template in wish I have 2 components that represents different Models. 我有一个模板希望我有2个组件代表不同的模型。 I need to create a model that contains both datas, for each component. 我需要为每个组件创建一个包含两个数据的模型。 If I have only one model everything works fine, but when I add other one, then this error happens in the console. 如果我只有一个模型一切正常,但是当我添加其他模型时,则在控制台中发生此错误。

The route of the template that contains the components is: 包含组件的模板的路由是:
App.EventsRoute = Ember.Route.extend({
model: function()
{
return Ember.RSVP.hash({
event: this.store.find('event'),
featured: this.store.find('event', 'featured')
});
}
});
Here is my template: 这是我的模板:
<script type="text/x-handlebars" id="events">
<div class="col-xs-8 pull-left">
{{#each event as |event|}}
{{#event-box event=event}}{{/event-box}}
{{else}}
no events
{{/each}}
...
{{#each featured as |highlight|}}
{{#highlight-event hlevent=highlight}}
{{/highlight-event}}
{{else}}
No Highlights
{{/each}}
...
</script>
Does anyone knows why this error happens and what can I do to solve it? 有谁知道为什么会发生这种错误,我该怎么做才能解决它?
this.store.find('event', 'featured')
is invalid. this.store.find('event', 'featured')
无效。
Also, find
is deprecated. 此外,不推荐使用find
。
With the latest Ember Data, you should use store.query() . 使用最新的Ember Data,您应该使用store.query() 。
You'd probably use it like 你可能会喜欢它
this.store.query('event', {featured: true})
or 要么
this.store.query('event', {filter: 'featured'})
You'll need to adjust your adapter accordingly. 您需要相应地调整适配器。 Something like: 就像是:
urlForQuery: function(query, modelName) {
if (query && query.featured === true) {
delete query.featured;
return this._buildURL(modelName, 'featured');
}
return this._super(query, modelName);
}
This should generate an URL like http://..../events/featured
. 这应该生成一个类似http://..../events/featured
的URL。
