Here is my ..models/category(category schema)
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);
add-category Route in admin.js file
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');
});
});
Here also server.js file to include the category
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);
when i run my server or route the add-category url then show module.js:549 throw err; this problem.
Here is my problem details and i check my code different times.
Then how can i solve this problem.

Seems to me that you forgot a /:
require('..models/category');
require('../models/category');
This is why ..models/category throws an error. From a general point of view, when require can't find a local module, don't "check the code", just check where the file is, and what path you wrote, it's always one or the other. ;)
