How to set id's for dynamic rows in angularjs - angularjs

Question

I have created a dynamic table using ngtable , and table data for 3 columns is fetched from json.In that table for 4th column a green/red color circle should come based on connection if successful or not.
The same i have done with javascript(without using json) in which for that 4th column i have set the four different id's,and based on id's i have changed the color using ajax if connection is successful.
In angular using json i m unable to do so , I have created the dynamic table but how to set id's and from where to get the image i'm unable to do.Can anyone help on this.
<table ng-table>
<thead>
<tr>
<th>Feature</th>
<th>DaysUp</th>
<th>Status</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="user in users">
<td>{{user.name}}</td>
<td>{{user.status}}</td>
</tr>
</tbody>
</table>

Answer 1

You can use scope id and index value to generate unique id. As ng-repeat creates child scope so you will get one scope id(unique id of scope) that id you can attach with $index.
<tr ng-repeat="user in users" id="{{$parent.$id+'-'+$index}}">
<td>{{user.name}}</td>
<td>{{user.status}}</td>
</tr>

HTML:
<div ng-app="myapp" ng-controller="myctrl">
<table>
<thead>
<tr>
<td>Name</td>
<td>DaysUp</td>
<td>Status</td>
</tr>
</thead>
<tbody>
<tr ng-repeat="user in users">
<td>{{user.name}}</td>
<td>{{user.daysup}}</td>
<td><img width="20px" height="20px" ng-src="{{imageurls[user.status-1]}}" /> </td>
</tr>
</tbody>
</table>
</div>
SCript:
angular.module('myapp',[])
.controller('myctrl',function($scope){
$scope.users =[
{'name':'xyz','daysup':2,'status':1},
{'name':'abc','daysup':4,'status':2},
{'name':'klm','daysup':6,'status':3},
{'name':'yrt','daysup':9,'status':4}
];
$scope.imageurls = [
'http://www.wpclipart.com/blanks/buttons/glossy_buttons/glossy_button_blank_yellow_circle.png',
