Using Or Condition in ng-repeat statement

How can I use a Or condition in ng-repeat. I currently have

<div ng-repeat="waterSample in viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE">

It can be viewRequest.data.REV_SAMPLE_CMQREQUEST sometimes. It should look for viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE or viewRequest.data.REV_SAMPLE_CMQREQUEST How can I solve this

Solution

To achieve expected result, use below ternary condition to check property use REV_SAMPLE_CMQREQUEST_WATER_SAMPLE in viewRequest.data and use REV_SAMPLE_CMQREQUEST_WATER_SAMPLE or REV_SAMPLE_CMQREQUEST based on condition

     <div ng-repeat="waterSample in viewRequest.data.hasOwnProperty('REV_SAMPLE_CMQREQUEST_WATER_SAMPLE')? viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE : viewRequest.data.REV_SAMPLE_CMQREQUEST">
{{wareSample}}
      </div>

working code sample

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
  $scope.viewRequest = {
    data: {
      REV_SAMPLE_CMQREQUEST_WATER_SAMPLE : [
        {id: 1, name: "test1"},
        {id: 2, name: "test2"}
      ],
      REV_SAMPLE_CMQREQUEST:[
        {id: 100, name: "ABC1"},
        {id: 200, name: "ABC2"}
      ]
    }
  }
  
  $scope.conditionalArr = $scope.viewRequest.data.hasOwnProperty('REV_SAMPLE_CMQREQUEST_WATER_SAMPLE')? $scope.viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE : $scope.viewRequest.data.REV_SAMPLE_CMQREQUEST
});

    {{waterSample.id}} {{waterSample.name}}
  </div>
