无法读取属性'on'未定义:Keystone.js中的错误
问题描述:
我一直在关注教程https://leanpub.com/keystonejs/read并尝试设置基本网站。无法读取属性'on'未定义:Keystone.js中的错误
对于本想建立一个路由/
以查看文件index.js
和模板在`index.twig”
以下是目录结构
routes/
|-- index.js
|-- middleware.js
`-- views
|-- blog.js
|-- contact.js
|-- gallery.js
|-- index.js
`-- post.js
templates/
|-- layouts
| `-- default.twig
|-- mixins
| `-- flash-messages.twig
`-- views
|-- assets -> public/assets/
|-- blog.twig
|-- contact.twig
|-- errors
| |-- 404.twig
| `-- 500.twig
|-- gallery.twig
|-- index.html -> templates/views/index.twig
|-- index.twig
|-- post.twig
models/
|-- Audience.js
|-- Element.js
|-- Enquiry.js
|-- Gallery.js
|-- Guide.js
|-- Post.js
|-- PostCategory.js
|-- Section.js
|-- Subsection.js
`-- User.js
以下是我keystone.js
,routes/index.js
和routes/views/index.js
文件。
// Simulate config options from your production environment by
// customising the .env file in your project's root folder.
require('dotenv').config();
// Require keystone
var keystone = require('keystone');
var Twig = require('twig');
// Initialise Keystone with your project's configuration.
// See http://keystonejs.com/guide/config for available options
// and documentation.
keystone.init({
'name': 'Bodhini',
'brand': 'Bodhini',
'less': 'public',
'static': 'public',

'views': 'templates/views',
'view engine': 'twig',
'twig options': { method: 'fs' },
'custom engine': Twig.render,
'auto update': true,
'session': true,
'auth': true,
'user model': 'User',
});
// Load your project's Models
keystone.import('models');
// Setup common locals for your templates. The following are required for the
// bundled templates and layouts. Any runtime locals (that should be set uniquely
// for each request) should be added to ./routes/middleware.js
keystone.set('locals', {
_: require('lodash'),
env: keystone.get('env'),
utils: keystone.utils,
editable: keystone.content.editable,
});
// Load your project's Routes
keystone.set('routes', require('./routes'));
// Configure the navigation bar in Keystone's Admin UI
keystone.set('nav', {
posts: ['posts', 'post-categories'],
galleries: 'galleries',
enquiries: 'enquiries',
users: 'users',
Guide: ['guides','sections','subsections','audiences'],
element:'elements',});
// Start Keystone to connect to your database and initialise the web server
路线/ index.js
var keystone = require('keystone');
var middleware = require('./middleware');
var importRoutes = keystone.importer(__dirname);
// Common Middleware
keystone.pre('routes', middleware.initLocals);
keystone.pre('render', middleware.flashMessages);
// Import Route Controllers
var routes = {
views: importRoutes('./views'),
};
// Setup Route Bindings
exports = module.exports = function (app) {
// Views
app.get('/', routes.views.index);
app.get('/blog/:category?', routes.views.blog);
app.get('/blog/post/:post', routes.views.post);
app.get('/gallery', routes.views.gallery);
app.all('/contact', routes.views.contact);
// NOTE: To protect a route so that only admins can see it, use the requireUser middleware:
// app.get('/protected', middleware.requireUser, routes.views.protected);
};
路线/视图/ index.js
var keystone = require('keystone');
exports = module.exports = function(req, res){
var view = keystone.View(req, res);
var locals = res.locals;
locals.data={
story:{},
work:{},
why:{},
disclaimer:{},
};
view.on('init', function(next){
var q = kestone.list('Element').model.findOne({slug: 'story'});
q.exec(function(err, result){
locals.data.story = result;
next(err);
});
});
view.render('index');
虽然我跑node keystone
,然后尝试在浏览器中打开路径/
,随着这个输出,我得到了一个404错误。

请指导我如何解决这个问题。我是新来的Node.js和快递/梯形
答
var view = keystone.View(req, res);
需求是
var view = new keystone.View(req, res);
,因为它是一个构造函数。 Keystone Docs
