라는 오류가 뜹니다.
detail.ejs
<h4>상세페이지 입니다.</h4>
<h4>제목 : <%= data.제목 %></h4>
<h4>날짜 : <%= data.날짜 %></h4>
server.js
app.get('/detail/:id', function(요청, 응답){
db.collection('post').findOne({ _id : parseInt(요청.params.id) }, function(에러, 결과){
응답.render('detail.ejs', {data : 결과} )
})
});
그대로 따라적었는데 왜이러는걸까요..?
/////
app.get('/detail/:id', function(요청, 응답){
db.collection('post').find().toArray(function(err, result){
응답.render('detail.ejs', { posts : result })
})
});
이런식으로하고
<h5 class="card-title"><%= posts[1].제목 %></h5>
<h6 class="card-subtitle mb-2 text-muted"><%= posts[1].날짜 %></h6>
잘나옵니다
