Trying to add comments to articles

Im trying to add comments to questions but im stuck and I dont know what i did wrong. After run program i see this error: TypeError: C:\Users\drobi\Desktop\projekty\SQLnode2\views\articles\show.pug:15 13| div 14| label(for="title") Title:

15| input(type="text", name="title" value=comment.title) 16| div 17| label(for="body") Body: 18| textarea(name="body")= comment.body

Cannot read property 'title' of undefined - I know what that error means but i dont know where my mistake is.

I created new model comment.js Theres a code: 'use strict'; const Sequelize = require('sequelize'); const moment = require('moment');

module.exports = (sequelize) => { class Comment extends Sequelize.Model { publishedAt() { const date = moment(this.createdAt).format("MMMM D, YYYY, h:mma"); return date; } } Comment.init({ title: { type: Sequelize.STRING, validate: { notEmpty: { msg: '"Title" is required' } } }, body: Sequelize.TEXT }, { sequelize });

return Comment; };

added new route comments.js:

const express = require('express'); const router = express.Router(); const Comment = require('../models').Comment;

function asyncHandler(cb){ return async(req, res, next) => { try { await cb(req, res, next) } catch(error){ res.status(500).send(error); } } }

/* GET comments listing. */ router.get('/:id', asyncHandler(async (req, res) => { const comments = await Comment.findAll({ order: [["createdAt", "DESC"]] }); res.render("articles/show", { comments, title: "Sequelize-It!" }); }));

/* Create a new comment form. */

router.get('/:id', (req, res) => { res.render("articles/show", { comment: {}, title: "New comment" }); });

// Post created Comment router.post('/:id', asyncHandler(async (req, res) => { let comment; try { comment = await Comment.create(req.body); } catch (error) { if(error.name === "SequelizeValidationError") { // checking the error comment = await Comment.build(req.body); res.render("articles/show", { comment, errors: error.errors, title: "New Comment" }) } else { throw error; // error caught in the asyncHandler's catch block } } }));

module.exports = router;

and added few lines of code to show.pug: extends ../layout

block content h2= article.title include by_line p= article.body a(href="../") ← Back | | a(href="/articles/" + article.id + "/edit") Edit Article | | a(href="/articles/" + article.id + "/delete") Delete Article form(action="/:id", method="post") div label(for="title") Title: input(type="text", name="title" value=comment.title) div label(for="body") Body: textarea(name="body")= comment.body input(type="submit")

Can someone please help me i cant solve this problem and i really would like to know wherem by mistake is. Thanks :D
