AngularJS ui-router:无法解决__ from state ___ Error

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/,我收到以下错误:

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

我将这个教程应用程序安装到我的Express.JS设置中,我正在使用Jade作为我的模板.

所有Jade模板似乎都正常呈现,但我注意到没有href为用户引号(settings/quotesURL)ui-sref链接创建.也许那里有一个线索.您可以在下面的屏幕截图中看到:

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!"
    };
}]);

玉模板

layout.jade

doctype html 
html
    include head
    body(ng-app='app')
        p From the layout.jade file
        <div ui-view></div>
        include scripts

settings.jade

ul
    li Settings
    li 
        a(ui-sref="settings") User Details
    li 
        a(ui-sref="settings/quotes") User Quotes
    div(ui-view="")

设置 - details.jade

h3 {{user.name}}\'s Quotes
hr
div
    label Quotes
        textarea(type="text", ng-model="user.quotes")
button(ng-click="done()") Save

设置 - quotes.jade

ExpressJS服务器

server.js

var express = require('express'),
mongoose = require('mongoose'),
morgan = require('morgan'),
bodyParser = require('body-parser'),
path = require('path');

var env = process.env.NODE_ENV = process.env.NODE_ENV || "发展";

var app = express();

// configuration
app.set('views', path.join(__dirname, '/app/views'));
app.set('view engine', 'jade');
app.use(morgan('dev')); // logs every request to console
app.use(bodyParser()); // pull information from html in POST
app.use(express.static(__dirname + '/public'));

// connect to mongodb via mongoose
if(env === 'development') {
  mongoose.connect('mongodb://localhost/3lf');
} else {
  mongoose.connect('mongodb://maxmythic:mongolab3lf@ds033307.mongolab.com:33307/3lf');
}

var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error ...'));
db.once('open', function(callback) {
  console.log('3lf db is open for business ...');
});

// create mongoose schema and retrieve data
var messageSchema = mongoose.Schema({message: String});
var Message = mongoose.model('Message', messageSchema);
var mongoMessage;
Message.findOne().exec(function(err, messageDoc){
  mongoMessage = messageDoc.message;
});

// define routes
// make sure to coordinate client side and server side routes
app.get('/partials/:partialPath', function(req, res) {
  res.render('partials/' + req.params.partialPath); 
});

app.get('*', function(req, res) {
  res.render('index', {
    mongoMessage: mongoMessage
  });
});


var port = process.env.PORT || 3030;
app.listen(port);
console.log('Listening on port ' + port + '...');

你几乎就在那里,ui-router需要这个:

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

这说ui-sref导航到命名状态'settings.details',如果我们需要传递params,它就像$ state.go一样非常相似......

<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是空字符串,就像我们的情况一样

     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',
            ...
        };

见文档:

UI的SREF

或新的文件 (引用)

ui-sref='stateName' - 导航到州,没有参数.'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
