这是我的..models / category(类别架构)
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const CategorySchema = new Schema({
name: { type: String, unique: true, uppercase: true}
});
module.exports = mongoose.model('Category', CategorySchema);
admin.js文件中的添加类别路由
const router = require('express').Router();
const Category = require('..models/category');
// add-category route
router.get('/add-category', function(req, res, next) {
res.render('admin/add-category', { message: req.flash('success') });
});
router.post('/add-category', function(req, res, next) {
var category = new Category();
category.name = req.body.name;
category.save(function(err) {
if (err) return next(err);
req.flash('success', 'Successfully added a category');
return res.redirect('/add-category');
});
});
这里的server.js文件也包含类别
const Category = require('./models/category');
app.use(function(req, res, next) {
Category.find({}, function(err, categories) {
if (err) return next(err);
res.locals.categories = categories;
next();
});
});
const adminRoutes = require('./routes/admin');
app.use(adminRoutes);
答案 0 :(得分:0)
在我看来您忘记了/
:
require('..models/category');
require('../models/category');
这就是..models/category
引发错误的原因。从一般的角度来看,当require
找不到本地模块时,不要“检查代码”,只需检查文件的位置以及您编写的路径,它总是一个或另一个。 ;)
