在初始化之前不能调用同位素上的方法；试图调用方法 'reLayout' angularjs

Question

使用 isotope 和 prettyPhoto 通过 angular js 创建我的图库视图，但出现 错误无法在 isotope 之前调用方法初始化;试图调用方法 'reLayout' 正在控制器中加载我的图库视图，如下所示：

index.html

<ng-view></ng-view>

app.js

angular.module("myapp", ["ngRoute", "ui.bootstrap", "slickCarousel"]).
config(function($routeProvider, $locationProvider) {
  $routeProvider.
  when("/home", {
    templateUrl: "partial views/home.html"
  })
}).controller("portfolioController", function($scope, $location) {
  //Portfolio
  $scope.$watch("$viewContentLoaded", function() {
    "use strict";
    var $container = $('.portfolio'),
      $items = $container.find('.portfolio-item'),
      portfolioLayout = 'fitRows';

    if ($container.hasClass('portfolio-centered')) {
      portfolioLayout = 'masonry';
    }
    var init = false;
    $container.isotope({
      filter: '*',
      animationEngine: 'best-available',
      layoutMode: portfolioLayout,
      animationOptions: {
        duration: 750,
        easing: 'linear',
        queue: false
      },
      masonry: {}
    }, refreshWaypoints());

    function refreshWaypoints() {
      init = true;
      setTimeout(function() {}, 1000);
    }

    $('nav.portfolio-filter ul a').on('click', function() {
      var selector = $(this).attr('data-filter');
      $container.isotope({
        filter: selector
      }, refreshWaypoints());
      $('nav.portfolio-filter ul a').removeClass('active');
      $(this).addClass('active');
      return false;
    });

    function getColumnNumber() {
      var winWidth = $(window).width(),
        columnNumber = 1;

      if (winWidth > 1200) {
        columnNumber = 5;
      } else if (winWidth > 950) {
        columnNumber = 4;
      } else if (winWidth > 600) {
        columnNumber = 3;
      } else if (winWidth > 400) {
        columnNumber = 2;
      } else if (winWidth > 250) {
        columnNumber = 1;
      }
      return columnNumber;
    }

    function setColumns() {
      var winWidth = $(window).width(),
        columnNumber = getColumnNumber(),
        itemWidth = Math.floor(winWidth / columnNumber);

      $container.find('.portfolio-item').each(function() {
        $(this).css({
          width: itemWidth + 'px'
        });
      });
    }

    function setPortfolio() {
      setColumns();
      if (init) $container.isotope('reLayout');
    }

    $container.imagesLoaded(function() {
      setPortfolio();
    });

    $(window).on('resize', function() {
      setPortfolio();
    });
  });
})

            </div><!-- end col-12 -->

        </div><!-- portfolio -->
    </div><!-- portfolio container -->
</div><!--/Portfoliowrap -->

如您所见，我还使用了 $scope.$watch("$viewContentLoaded", 来确保视图已加载。但仍然出现上述错误。 Isotope 工作正常，但 prettyphoto 不工作，这可能是因为这个错误。希望得到一些指导。

好吧，在 @charlietfl - [非常感谢好友] 的帮助下，我解决了这个问题directives 的帮助。下面是示例代码。

app.js

angular.module("myapp", ["ngRoute", "ui.bootstrap", "slickCarousel"]).
config(function($routeProvider, $locationProvider) {
  $routeProvider.
  when("/home", {
    templateUrl: "partial views/home.html"
  })
}).controller("portfolioController", function ($scope, $location) {
    //Portfolio
    $scope.update = function () {
        $scope.imgList = [{
            url: "img/portfolio/portfolio_09.jpg",
            href: "assets/img/portfolio/portfolio_09.jpg",
            desc: "A Graphic Design Item"
        },
        {
            url: "/img/portfolio/portfolio_02.jpg",
            href: "assets/img/portfolio/portfolio_02.jpg",
            desc: "A Web Design Item"
        },
        {
            url: "/img/portfolio/portfolio_03.jpg",
            href: "assets/img/portfolio/portfolio_03.jpg",
            desc: "A Web Design Item"
        }];
    }
    $scope.update();
}).directive('isoRepeat', function ($timeout) {
    return {
        scope: {
            items: '=isoRepeat'
        },
        template: '<div class="portfolio-item graphic-design" ng-repeat="item in items"><div class="he-wrap tpl6"><img ng-src="{{item.url}}" /><div class="he-view">'
