AngularJS ui-router:无法从状态 ___ 错误中解析___ [英] AngularJS ui-router : Could not resolve___ from state ___ Error

问题描述

我正在学习今年的 ui-router 教程

或新文档(引用)

<块引用>

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

I am following along on this year old ui-router tutorial http://txt.fliglio.com/2013/05/angularjs-state-management-with-ui-router/ and I'm getting the following error:

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

I am fitting this tutorial app into my Express.JS setup and I'm using Jade for my templates.

All the Jade templates seem to be rendering properly but I am noticing that there is no href being created for the User Quotes (settings/quotes URL) ui-sref link. Maybe there is a clue there. You can see this in the below screenshot:

I will post all key files below.

AngularJS Files

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 = {

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

ExpressJS Server

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 || 'development';

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:[e-mail]: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 + '...');

解决方案

You are almost there, ui-router needs this:

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

this says ui-sref navigate to state named 'settings.details', in case we would need to pass params, it is very similar like $state.go...

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

if we want to use url defined for states, we still can, but we must use href

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

if the child url is empty string like in our case

     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',
            ...
        };

See documentation:

ui-sref

or new doc (cite)

ui-sref='stateName' - Navigate to state, no params. 'stateName' can be any valid absolute or relative state, following the same syntax rules as $state.go()
