Using meteor to display templates with input parameters

I have set up iron routes in my router to render a specific template using the following code:

var Home = RouteController.extend({
    ....
    action: function () {
        if (this.ready()) {
          this.render('main', {state: 'normal'});
        }
        else {
          ;//this.render('loading');
        }
    }
});

In my implementation, I am trying to pass a state variable to the template and utilize it within the class attribute like so:

<template name="main">
    <section class="{{state}}">
        ....
    </section>
</template>

Unfortunately, the state variable appears to be undefined, indicating that my current approach is not functioning correctly. Can anyone provide suggestions on how I can effectively pass data to the template?

Answer №1

In my opinion, utilizing the data option would be the most effective approach.

var Home = RouteController.extend({
    data:{state:'normal'},
    action: function () {
        if (this.ready()) {
          this.render('main');
        }
        else {
          ;//this.render('loading');
        }
    }
});

The data can also be a function which, if it includes a reactive data source, will re-run each time the data changes.

A few things to consider though. If you have a loadingTemplate specified for the route and your subscriptions are being returned from wait on.. iron-router will take care of rendering the loading template automatically for you.

Additionally, the data option is meant to return a single document, and when that does not exist iron-router will render the notFound template for that route. Managing template state should ideally be done through template helpers.
