            "date": "Aug 6, 2016 10:57:07 AM"
        },
        {
            "sender": "player",
            "message": "This is the message tooo",
            "date": "Aug 6, 2016 10:57:07 AM"
        }
    ]
}
]

But I can't find how can ng-repeat theese. When I wrote {{data.sender}} returns error [ngRepeat:dupes] in console.

I need list this values in ticket-list page, this is a support system for users.

Answer 1

Try this, Here is working fiddle.
Also check the Angular version, It should minimum 1.2, since it was introduced in that version.

 <div ng-controller="MyCtrl">
  <div ng-repeat="data in datas track by $index">
    Sender : {{data.sender}}
    <br> Messages :<br>
    <div ng-repeat="(mindex, mvalue) in data.messages">
       {{mindex+1}}. {{mvalue.message}} - {{mvalue.date}}
    </div>
    <br>
  </div>
</div>

Answer 2

Let's assume your object is in the value of the variable $scope.data.

Then you can render this in your html with angular as following:

<div ng-repeat="item in data track by $index">
    {{ item.id }}
</div>

Update: Indeed, with this specific error you need track by $index

Answer 3

You are getting [ngRepeat:dupes] error in console because there are some duplicates in the data.

If you want to loop through all the data and show sender, You can do something like this

<div ng-repeat="data in jsonData track by $index">{{data.sender}}</div>

$index keeps track of each object in the array using index of the object in the array.
