Jade, how to display the field of an object?

Question

Node.js

An array of objects is passed to the jade template, then the objects themselves are enumerated, which have the following structure:

{ _id: 53e91147ce282615c3f61423,
  author: 'Автор Имя',
  title: 'Заголовок',
  date: '09.02.2013',
  genre: 'жанр',
  genre_id: 2 }

Output Code

-var t = ""
pre #{verses[0]}
-for verse in verses
  ul
    -if(t != verse.author)
      -var t = verse.author
        span.author #{verse.author}

      li 
        span
          a(href='/verse/'+verse.id) #{verse.title}
          span #{verse.genre_id}
          a(href='/verse/find/'+verse.genre_id) #{verse.genre}

All fields are displayed correctly, except for genre_id, when the entire object is displayed, it is, but when the genre_id itself is displayed, I get undefined. What could be the problem? And how to decide?

Answer 1

Try outputting verse.genreId. I'm not sure, but this is the first thing I would try, since this is the main difference from other attributes

Answer 2

_id: 53e91147ce282615c3f61423,

The value must be in quotes.
_id: '53e91147ce282615c3f61423',

Answer 3

verse['genre_id']
