用ng错误-用这个关键字和控制器替换$scope时重复

Question

在控制器中，我已经从使用$scope对象转换为vm = this。我知道您必须在controllerAs或view中声明一个state。

我有两个使用ng-repeat的表，第一个很好，所有的数据都被填充，但是第二个表由于某种原因没有被填充。我已经玩了一遍，用户单击的项被记录在控制台中，但是第二个表没有填充数据。和$scope合作得很好。

知道我哪里出问题了吗？

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

app.config(['$stateProvider', '$locationProvider', '$urlRouterProvider', '$routeProvider',  function($stateProvider, $locationProvider, $urlRouterProvider, $routeProvider) {

    $urlRouterProvider
        .when('/', '/patents/')
        .otherwise('/patents/');

    $stateProvider
        .state("patents", {
            url: "/patents",
            templateUrl: "templates/patents/list/list-patents.htm",
            controller: "patentCtrl",
            controllerAs: "patents"
        })
        .state("patents.item", {
            url: "/:id",
            templateUrl: "templates/patents/list/patent-item.htm",
            controller: "patentCtrl",
            controllerAs: "item"
        })
}]);

app.factory('patentsService', function($http, $q) {

    var factory = {};

        var REST_SERVICE_URI = 'http://localhost:8080/Sprint002b/restpatent/';

        factory.fetchAllPatents = function() {

            var deferred = $q.defer();
             $http.get(REST_SERVICE_URI)
                .then(
                function (response) {
                    deferred.resolve(response.data);
                },
                function(errResponse){
                    console.error('Error while fetching Users');
                    deferred.reject(errResponse);
                }
            );

            return deferred.promise;
        }

        factory.select = function(item) { 
            selectedItem = item;
            return selectedItem;
        }        

    return factory;

});

app.controller('patentCtrl', ['patentsService', function(patentsService) {

    var vm = this;

    vm.patent={id:null, patentApplicationNumber:'', clientRef: '', renewalStatus: '', currentRenewalCost: '', costBandEndDate:'', renewalCostNextStage:'', renewalDueDate:''};
    vm.patents=[];

    vm.select = function(item) {
       vm.patentItem = patentsService.select(item); //THIS SHOULD POPULATE TABLE
       console.log(vm.patentItem)
    }

    vm.fetchAllPatents = function(){

        patentsService.fetchAllPatents()
            .then(
            function(d) {
                vm.patents = d;
            },
            function(errResponse){
                console.error('Error while fetching Users');
            }
        );
    }

    vm.fetchAllPatents();

}]);

然后，您应该为patents.item状态创建一个新的单独控制器。在加载时，您将只从patentsService中检索当前选定的项。

//config
.state("patents.item", {
    url: "/:id",
    templateUrl: "templates/patents/list/patent-item.htm",
    controller: "patentItem", //<-- controller added here
    controllerAs: "item"
})
//patenItem new controller
.controller('patentItem', ['patentsService', function(patentsService) {
    var item = this;
    item.select = function(items) {
        vm.patentItem = patentsService.select(item);
        console.log(vm.patentItem)
    };
    function init(){
       item.select();
    }
    init();
}]);
