在 Emberjs 中设置从路由到控制器错误的数据

2022-01-19 00:00:00 frontend javascript model-view-controller ember.js

我是 Emberjs 的新手..我正在尝试设置从 Emberjs 路由到控制器的数据内容以在模板中显示..

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

我遵循了这里的建议..访问控制器函数内的内容 ember

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

完美运行.. 但现在我收到此错误

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}

这也是我的代码..

任何反馈都将不胜感激

谢谢

推荐答案

你的问题是 https://torid-heat-7210.firebaseio.com/fixed_column.json 返回一个对象 ({}) 其中 {{#each}}helper 需要一个数组 ([]).

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

您可以如下修改您的 setupController 方法以使其工作:

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);
  })
}
