在Emberjs中将数据从路由设置到控制器错误 [英] setting data from route to controller error in Emberjs

问题描述

我是Emberjs中的新手。
我试图将数据内容从Emberjs路由设置到控制器以显示在模板中。

我跟随这里的建议..
访问控制器功能内的内容ember

完美的工作...但现在我收到这个错误

 未捕获错误：断言失败：#each循环的值必须是数组。您通过{items：[object Object]，[object Object]，[object Object]，[object Object]，[object Object]，[object Object]，title：current mood} 
  

编辑：
这里也是我的代码..

这里是我的模板代码

任何反馈将不胜感激

谢谢

解决方案

您的问题是 https://torid-heat-7210.firebaseio.com/fixed_column.json 返回一个Object（ {} ）where as code> {{＃each}} 帮助器期待一个数组（ [] ）。

您可以将 setupController 方法修改为接下来让它工作：

  setupController：function（controller）{
 Ember。$。ajax（{
 url：'https://torid-heat-7210.firebaseio.com/fixed_column.json'，
 type：'GET'
}）。done（function（data）{
 controller.set（'content'，data.items）; 
}）
}

i am a newbie in Emberjs.. I am trying to set data content from Emberjs route to controller to display in template..

i followed the suggestions here.. Access content inside a controller function ember

works perfect.. but now i am getting this error

Uncaught Error: Assertion Failed: The value that #each loops over must be an Array. You passed {items: [object Object],[object Object],[object Object],[object Object],[object Object],[object Object], title: current mood}

edit: here is also my code..

and here is my template code

any feedback would be appreciated

thanks

解决方案

Your problem is that https://torid-heat-7210.firebaseio.com/fixed_column.json returns an Object ({}) where as {{#each}} helper is expecting an array ([]).

You can modify your setupController method as follows to get it to work:

setupController: function(controller){
  Ember.$.ajax({
    url: 'https://torid-heat-7210.firebaseio.com/fixed_column.json',
    type: 'GET'
  }).done(function(data){
    controller.set('content', data.items);
  })
}
