Question

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不会将产品数据传递给index.ect。你能说出如何解决这个问题吗？

错误：无法查找视图＆＃34;错误＆＃34;在views目录＆＃34; / Users / toshihirokaseda / bitcore_test / Realarts / views＆＃34;

//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;

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');

你应该有目录结构：

Realarts/
├──_views
   ├──index.ect

同样在index.js文件中，您没有导出router。您需要在collection.js：

中添加此行

module.exports = router;

当我将数据从index.js传递给index.ect时，我无法在Node.js上显示模型值
