AngularJS ui-router：无法从状态___错误解析___

Question

我正在关注今年的 ui-router 教程 http://txt.fliglio.com/2013/05/angularjs-state-management-with-ui-router/，但出现以下错误：

Error: Could not resolve 'settings/quotes' from state 'settings'

我正在将此教程应用程序安装到我的 Express.JS 设置中，并且我正在使用 Jade 作为我的模板。

所有 Jade 模板似乎都可以正确呈现，但我注意到没有为 User Quotes (settings/quotes URL) ui-sref 链接创建 href。也许那里有一个线索。您可以在下面的屏幕截图中看到这一点：

我将在下面发布所有关键文件。

AngularJS 文件

app.js

'use strict';

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

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

      $urlRouterProvider.otherwise('/');

            var settings = {
                name: 'settings',
                url: '/settings',
                abstract: true,
                templateUrl: '/partials/settings',
                controller: 'SettingsController'
            };

            var details = {
                name: 'settings.details',
                parent: settings,
                url: '',
                templateUrl: '/partials/settings-details'
            };

            var quotes = {
                name: 'settings.quotes',
                parent: settings,
                url: '/quotes',
                templateUrl: '/partials/settings-quotes'
            };

            $stateProvider
                .state(settings)
                .state(details)
                .state(quotes);
}])
.controller('SettingsController', ['$scope', function($scope) {
    $scope.user = {
        name: "Bob Loblaw",
        email: "boblaw.bob@loblaw.org",
        password: "semi secret",
        quotes: "I am making it happen now!"

你快到了，ui-router 需要这个：

<a ui-sref="settings.details">...

这表示ui-sref 导航到名为'settings.details' 的状态，以防我们需要传递参数，它与$state.go 非常相似...

<a ui-sref="settings.details({param1:value1, param2:value2})">...

如果我们想使用为状态定义的url，我们仍然可以，但我们必须使用href

<a href="#/settings">...to get to details
<a href="#/settings/quotes">...to get to quotes

如果子 url 像我们的例子一样是空字符串

     var settings = {
            name: 'settings',
            url: '/settings',
            abstract: true,
            ...
        };

     var details = {
            name: 'settings.details',
            parent: settings,
            url: '',
            ...
        };
     var quotes = {
            name: 'settings.quotes',
            parent: settings,
            url: '/quotes',
            ...
        };

查看文档：

ui-sref

或new doc（引用）

ui-sref='stateName' - 导航到状态，无参数。 'stateName' 可以是任何有效的绝对或相对状态，遵循与 $state.go() 相同的语法规则
