Dynamic templates in EJS (node.js)

Question

Does anybody know a nice solution for including templates, whose names would be known only at run time? EJS's includes allows only to specify exact file/template name.

Use case : I have a article layout and there is article HTML/EJS content in some local file.

To do so I need something like https://github.com/visionmedia/ejs#includes but file name should be taken from locals variable:

Assume I have such handler (simplified):

app.get('/article/:article', function (req, res) {
        var articleContent = req.params.article;
        res.locals.articleContent = 'data/'+articleContent;
        return res.render('article.ejs')
    })

And in article.ejs (assume having ejs-locals):

<% layout('layout') -%>
<section>
  <article class="single-country">
      <% include ???articleContent???  %>
  </article>
</section>

Is there any possibility to do so or is the only option is to load article content and put into articleContent, so available by <%- articleContent %> ?

The problem with this solution is that the content of article should be plain html (`<%- -%>' do not interpolate value). So if inside article I need to use any EJS feature, I need to compile/render by myself.

Maybe someone else already knows how this can be done with some dynamic include helper for EJS so no need of additional code?

Looks like this is now supported in EJ S. It was introduced in v2.0.1: 2015-01-02 . The new syntax looks like this

 <%- include(articleContent) %>

I had to disable caching in Express by setting: 我必须通过设置禁用Express中的缓存：

app.set('view cache', false);

You can use a filter like this:

var ejs = require('ejs');
var fs = require('fs');

ejs.filters.article_teaser = function(my_object) {
    return ejs.render(fs.readFileSync(__dirname + '/views/' + my_object.template + '.ejs', 'utf8'), {my_object: my_object});
}

On your template just use:

<%-: article | article_teaser %>

Cheers!
