如何在单个ng-repeat中对其他对象内部的对象中的数组项使用ng-repeat

$scope.items = [
  {
    name: 'Item 1',
    details: [
      { description: 'Detail 1.1' },
      { description: 'Detail 1.2' }
    ]
  },
  {
    name: 'Item 2',
    details: [
      { description: 'Detail 2.1' },
      { description: 'Detail 2.2' }
    ]
  }
];

<div ng-app="myApp" ng-controller="myController">
  <div ng-repeat="item in items">
    <h3>{{ item.name }}</h3>
    <ul>
      <li ng-repeat="detail in item.details">{{ detail.description }}</li>
    </ul>
  </div>
</div>

var app = angular.module('myApp', []);

app.controller('myController', function($scope) {
  $scope.items = [
    {
      name: 'Item 1',
      details: [
        { description: 'Detail 1.1' },
        { description: 'Detail 1.2' }
      ]
    },
    {
      name: 'Item 2',
      details: [
        { description: 'Detail 2.1' },
        { description: 'Detail 2.2' }
      ]
    }
  ];
});

$scope.items.forEach(function(item) {
  if (!item.details) {
    item.details = [];
  }
});
