我想在 Node.js 上显示模型值，但是浏览器返回以下错误。我想获取产品数据并显示它，但似乎index.js没有将产品数据传递给index.ect。你能告诉我如何解决这个问题吗？
错误:无法在 View 目录“/Users/toshihirokaseda/bitcore_test/Realarts/views”中查找 View “错误”
//collection.js
var express = require('express');
var router = express.Router();
var model = require('../model.js'),
User = model.User;
/* GET users listing. */
router.get('/collection', function(req, res, next) {
res.render('collection', { name: req.session.user});
});
module.exports = router;

最佳答案
试试这个:
var ectRenderer = ECT({ watch: true, root: __dirname + '/views', ext : '.ect' });
app.set('views', path.join(__dirname,'/views'));
app.engine('ect',ectRenderer.render);
app.set('view engine','ect');
您应该具有目录结构:
Realarts/
├──_views
├──index.ect
此外，在您的 index.js 文件中，您也不会导出路由器。您需要添加此行，因为您的 collection.js 中已包含此行:
module.exports = router;
关于node.js - 当我将数据从 index.js 传递到 index.ect 时，我无法在 Node.js 上显示模型值，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33630524/
