I don't know why the card is not showing.
Here is my code for the card.pug
extends app
block card
section(class=`flashcards`)
.card(class=`card-${side}`)
.card-header
h1.card-title= side
#content
h2= text
if hint
p.hint
i= hint
.card-flip-wrap
a(href=`${id}?side=${sideToShow}`)
img.card-flip(src='/static/img/flip.svg')
.card-next
a(href='/cards')
img(src="/static/img/next.svg")
script(src='/static/js/app.js')
and for the card.js
const express = require('express');
const router = express.Router();
const { data } = require('../data/flashcardData.json');
const { cards } = data;
router.get('/', (req, res) => {
const numberOfCards = cards.length;
const flashcardId = Math.floor(Math.random() * numberOfCards);
res.redirect(`/cards/${flashcardId}`);
});
router.get('/:id', (req, res) => {
const { side } = req.query;
const { id } = req.params;
if (!side) {
return res.redirect(`/cards/${id}?side=question`);
}
const name = req.cookies.username;
const text = cards[id][side];
const { hint } = cards[id];
const templateData = { id, text, name };
if (side === 'question') {
templateData.hint = hint;
templateData.sideToShow = 'answer';
templateData.sideToShowDisplay = 'Answer';
} else if (side === 'answer') {
templateData.sideToShow = 'question';
templateData.sideToShowDisplay = 'Question';
}
res.render('card', templateData);
});
module.exports = router;
Any help would be much appreciated.

15,402 PointsHey Brian, your code looks a little different than mine but your output issue looks similar to what I was experiencing. In looking at the pug documentation, this format is not longer supported for attributes:
class=card-${side}
According to the documentation, attributes with variables need to be specified with a +. In your example, (class="card-" + side).
This fixed the problem for me. You can read about this here: https://pugjs.org/language/attributes.html. Scroll down to the section: Attribute Interpolation.
I hope Andrew/Treehouse update this course as it took a while to figure out what the problem was and I think this change should be reflected in the learning materials.
Hope this helps!

11,314 PointsHello Brian! Please check your code in card.js in ninth rows and correct it res.redirect(
/cards/${flashcardId}?side=question
) you lost the query string. I cant see your public folder, but inserted your img folder-js folder-stylesheets folder into public folder. You remember the static way equal to public folder. I hope I helped. Have a nice day!
