as far as i now ejs (as most of other template engines) does not support
asynchronous helper. you have to fetch the comments first and then pass
them to your template rendering
in your controller:
function(req, res, params){
var debate = //resolve the debate
*
debate.getComments(function(err,comments){
*
*
console.log(comments.length);
self.respond({comments: comments, debate: debate})
});
*
}
in view
*<%= comments.length; %>*
