Редактирование CRUD с помощью JayData и AngularJs

2 user517406 [2014-03-19 23:56:00]

Я пытаюсь создать базовое приложение CRUD с использованием JayData, AngularJS и OData Web Api. Я дошел до создания представления "Список" и вида "Редактировать", и, щелкнув параметр "Редактировать" для элемента в представлении "Список", он успешно перенаправляется в представление "Редактировать" и заполняется, как ожидалось. Однако, когда я вернусь к представлению "Список" и выберите последующие опции "Редактировать", представление "Редактировать" не будет заполнено. Вот мой соответствующий Угловой код:

EDIT: Вот мой полный код, по просьбе:

app.js:

    var app = angular.module("app", ["localization", "ngResource", "ngRoute", "jaydata"]).
    config(function ($routeProvider, $locationProvider) {
        $routeProvider.
            when('/Admin/Fixtures/List', { controller: FixtureListController, templateUrl: '/Content/Templates/Fixtures.html' }).
            when('/Admin/Fixtures/Add', { controller: FixtureAddController, templateUrl: '/Content/Templates/FixtureAddEdit.html' }).
            when('/Admin/Fixtures/Edit/:fixtureId', { controller: FixtureEditController, templateUrl: '/Content/Templates/FixtureAddEdit.html' }).
            otherwise({ controller: TeamListController, redirectTo: 'Admin/Teams/List', templateUrl: '/Content/Templates/Teams.html' });
        $locationProvider.html5Mode(true); //will use html5 mode rather than hashbang where available
    });

var FixtureListController = function ($scope, $data) {

    $scope.fixtures = [];
    $scope.context = [];
    $scope.selectedFixture = null;

    $data.initService('http://lovelyjubbly.cloudapp.net/odata')
    .then(function (context) {
        $scope.context = context;
        $scope.fixtures = context.Fixtures.include('Stage').include('HomeTeam').
                                include('AwayTeam').include('City').toLiveArray();
    });

    $scope.delete = function () {

        //get id, can use this to get item from ng-repeat
        var emp = new lovelyjubblyWebApi.Models.Fixture({ FixtureId: this.fixture.FixtureId });

        $scope.context.Fixtures.remove(emp);
        $scope.context.saveChanges();
    };
};

//crud controllers
var FixtureAddController = function ($scope, $data) {

    $scope.fixtures = [];

    $data.initService('http://lovelyjubbly.cloudapp.net/odata')
    .then(function (context) {
        $scope.context = context;
        $scope.fixtures = context.Fixtures.toLiveArray();
        $scope.teams = context.Teams.toLiveArray();
        $scope.cities = context.Cities.toLiveArray();
        $scope.stages = context.Stages.toLiveArray();
    });

    $scope.save = function () {

        //prevents a separate post
        $scope.fixture.entityState = $data.EntityState.Modified;
        $scope.context.Fixtures.add($scope.fixture, true);
        $scope.context.saveChanges();

        //reset state
        $scope.context.stateManager.reset();
    };
};

var FixtureEditController = function ($scope, $data, $routeParams) {

    $scope.context = [];
    $scope.fixtures = [];
    $scope.teams = [];
    $scope.cities = [];
    $scope.stages = [];
    $scope.selectedFixture = null;
    $scope.fixture = null;


    $data.initService('http://lovelyjubbly.cloudapp.net/odata')
    .then(function (context) {
        $scope.context = context;
        $scope.fixtures = context.Fixtures.include('Stage').include('HomeTeam').
                                include('AwayTeam').include('City').toLiveArray();
        $scope.teams = context.Teams.toLiveArray();
        $scope.cities = context.Cities.toLiveArray();
        $scope.stages = context.Stages.toLiveArray();

        var emp = new lovelyjubblyWebApi.Models.Fixture({ FixtureId: $routeParams.fixtureId });

        $scope.context.Fixtures.filter('FixtureId', '==', $routeParams.fixtureId)
            .forEach(function (item) {
                emp.StageId = item.StageId;
                emp.CityId = item.CityId;
                emp.FixtureDate = item.FixtureDate;
                emp.HomeTeamId = item.HomeTeamId;
                emp.HomeTeamScore = item.HomeTeamScore;
                emp.AwayTeamId = item.AwayTeamId;
                emp.AwayTeamScore = item.AwayTeamScore;
            }).then(function (e)
            {
                $scope.fixture = emp;
            });

        $scope.save = function () {

            if ($scope.form.$valid) { //check for valid form

                var todo = $scope.context.Fixtures.attachOrGet({ FixtureId: $routeParams.fixtureId });
                todo.StageId = $scope.fixture.StageId;
                todo.CityId = $scope.fixture.CityId;
                //emp2.FixtureDate = $scope.fixture.FixtureDate;
                todo.FixtureDate = "10/10/2014 00:00";
                todo.HomeTeamId = $scope.fixture.HomeTeamId;
                todo.HomeTeamScore = $scope.fixture.HomeTeamScore;
                todo.AwayTeamId = $scope.fixture.AwayTeamId;
                todo.AwayTeamScore = $scope.fixture.AwayTeamScore;
                $scope.context.saveChanges();
            } else {
                alert("invalid form"); 
            }
        };
    });
};
