title: How to bypass Firebase auto-add Id when importing JSON
body: <p>I have a json file:</p>
  
  <pre><code>{
  "events": [
      {
          "title": "Wydarzenie 1",
          "start": "2015-03-19"
      },
      {
          "title": "Wydarzenie 2",
          "start": "2015-03-20"
      },
      {
          "title": "Wydarzenie 3",
          "start": "2015-03-21"
      }
  ]
  </code></pre>
  
  <p>}</p>
  
  <p>But when I import the file to firebase it gets changed to:</p>
  
  <pre><code>{
  "events": [
      "0": {
          "title": "Wydarzenie 1",
          "start": "2015-03-19"
      },
      "1": {
          "title": "Wydarzenie 2",
          "start": "2015-03-20"
      },
      "2": {
          "title": "Wydarzenie 3",
          "start": "2015-03-21"
      }
      ]
  }
  </code></pre>
  
  <p>I want to have it in the same format as imported or at least retreive the data in imported format (no auto-id's e.g. 0, 1, 2). I need it to pass it as an argument to FullCallendar $scope.eventSources =[]. Could you tell me how to do that please?</p>
