Exploring Handlebars.js: Understanding the Scope of Global Contexts

If I have a static list of cached users within my application under App.Users, there will likely be various instances where I need to display the list of users. Typically, I would just pass the list along with the context to the template.

var tmpl = Handlebars.templates['TemplateName'];

var html = tmpl({
    model: model,
    users: App.Users
});

However, this method involves setting up connections in both the template and the javascript code. Ideally, I would prefer to handle this directly in the template so that it doesn't have to be remembered in the scripts. For example...

{{#each {{users}}}}
    <li> ... </li>
{{/each}}

In this scenario, the users helper function simply returns App.Users. Wouldn't that be convenient?

Unfortunately, this code snippet does not actually compile. Are there any other solutions available?

Answer №1

Decided to implement a unique helper function approach... because let's face it, this seems to be the answer for most Handlebars inquiries.

Handlebars.registerHelper('custom', function(data, options) {
    return options.fn(App.[data].toJSON()); // Data is coming from Backbone Collection
})

Illustrated with an example...

{{#custom "Customers"}}
    {{#each this}}
         <td>{{Name}}</td>
    {{/each}}
{{/custom}}
