Handlebars cannot see the added view helpers

[revelfire]

The view sample presented isn't working for me.

here's my test:

var User = Backbone.Model.extend(); var HelloView = Backbone.HandlebarsView.extend({ template: 'Hello {{name}}' }) var AppView = Backbone.HandlebarsView.extend({ template: '

Hello

{{view "HelloView" model=this}}' }); var app = new AppView({model: new User({name: 'Foli'})}); console.log(app.render().$el.html());

I am using the current version of the plugin, the latest backbone and jquery. I am using requirejs. Here's the entire code dump:

Hi, looks to be an issue with the latest versions of Handlebars: your example works for me with Handlebars 1.0.0-rc.3. Can you confirm me that you encounter this issue with a newer version (1.0.0.rc.4 or 1.0.0)?

In the meantime, I'm gonna investigate. Thanks for reporting!

Yep! Thanks for your response.

#Snippet:

Handlebars.VERSION = "1.0.0";
Handlebars.COMPILER_REVISION = 4;

Handlebars.REVISION_CHANGES = {
    1: '<= 1.0.rc.2', // 1.0.rc.2 is actually rev2 but doesn't report it
    2: '== 1.0.0-rc.3',
    3: '== 1.0.0-rc.4',
    4: '>= 1.0.0'
};

Loicfrering, thanks for any support :)

Additional research here. Per you comment I punted back to 1.0.0-rc3. It 'partially' works. Result is:

Hello

testTemplate.html:54 GET http://localhost:8080/js/HelloView.js 404 (Not Found) require-with-comments.js:1872 Uncaught Error: Script error for: HelloView http://requirejs.org/docs/errors.html#scripterror require-with-comments.js:163

So it seems to partially work - we get through the first render but die trying to get HelloView inserted in the subview render.

Given that result I thought maybe something weird was happening with the AMD/require stuff, so I did a trimmed down version. Same code, but no AMD. Technically same result - cannot find HelloView.

<script type="text/javascript">
    $(function() {
        var User = Backbone.Model.extend();
        var HelloView = Backbone.HandlebarsView.extend({
            template: 'Hello {{name}}'
        })
        var AppView = Backbone.HandlebarsView.extend({
            template: '<h1>Hello</h1>{{view "HelloView" model=this}}'
        });
        var app = new AppView({model: new User({name: 'Fool'})});
        console.log(app.render().$el.html());
    });

</script>

RESULT: Uncaught Error: Cannot resolve view "HelloView" backbone.handlebars.js:65

This example is still pretty much exactly what is in the docs so I'm not sure what's going on.

Thanks, Chris

The HelloView must be accessible outside of your module pattern function in order to be resolved by Backbone.Handlebars, you can either:

• attach it to the window global object: window.HelloView = ...
• attach it to some sort of global namespace: App.HelloView = ... and then {{view "App.HelloView" ...}}
• if Backbone.Handlebars detects require.js, it will try to load the HelloView module, so you just have to declare this HelloView in a dedicated module

FYI, here is the view resolution related code.
