setting data from route to controller error in Emberjs

问题

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..

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);
  })
}

Working solution here
