Шаблон пыли для вложенных математических условий

Question

Я хочу вывести HTML-таблицу с 4 записями для каждой строки, используя шаблоны пыли.

вот шаблон:

var compiledtlist = dust.compile(
            "<table class='table'>" +
            "{#data}" +
            "{@math key=\"{tagid}\" method=\"mod\" operand=\"4\"}" +
            "{@eq value=0}" +
            "<tr><td><button class='btn btn-mini btn-info tag'>{tname}</button>&nbsp;x&nbsp; <span class='badge badge-info'>10</span> <br /><p>{tdesc}</p></td>" +
            "{/eq}" +
            "{@eq value=3}" +
            "<td><button class='btn btn-mini btn-info tag'>{tname}</button>&nbsp;x&nbsp; <span class='badge badge-info'>10</span> <br /><p>{tdesc}</p></td></tr>" +
            "{/eq}" +
            "{@default}" +
            "<td><button class='btn btn-mini btn-info tag'>{tname}</button>&nbsp;x&nbsp; <span class='badge badge-info'>10</span> <br /><p>{tdesc}</p></td>" +
            "{/default}" +
            "{/math}" +
            "{/data}" +
            "</table>"
            , "taglist");
            console.log(compiledtlist);
            dust.loadSource(compiledtlist);
            dust.render("taglist", { data: data }, function (err, out) {
                console.log(err);
                console.log(out);
                $('#tagstable').html(out);
            });

и данные:

[

      "tagid":10,
      "tname":"sql server",

   }

К сожалению, шаблон не возвращает ничего, кроме тегов таблицы.

что мне здесь не хватает?

Математический тег неправильный?

Answer 1

Ваш код в порядке. Проблема в том, что вы должны явно требовать dustjs-helpers, Я считаю, что это должно быть правильно упомянуто в документации.

1. Вам необходимо установить dustjs-helpers

   npm install dustjs-helpers
   

2. В коде вам нужна эта строка

   require("dustjs-helpers");
   

После выполнения этих шагов я получил сгенерированный HTML.
