Rails：无法识别Ember.js车把模板

Question

I have a fairly basic question.

I am learning Ember.js to be used with a Rails backend. I can get things to work when templates are mentioned inline in the HTML file.

<script type="text/x-handlebars" id="index">
<div class="container-fluid">
    <div class="row-fluid">
        <div class="span3">
            <table class='table'>
                <thead>
                <tr><th>Recent Posts</th></tr>
                </thead>
                {{#each item in model}}
                    <tr><td>
                        {{item.name}}
                    </td></tr>
                {{/each}}
            </table>
        </div>
        <div class="span9">
            {{outlet}}
        </div>
    </div>
</div>
</script>

But the minute I moves this snippet to a .hbs file under templates directory, and include the following line in my application.js file,

#= require_tree ./templates

they fail with this error.

Assertion failed: You specified the templateName cms2/index for <CMS.IndexView:ember229>, but it did not exist. 

I have tried to precompile then using two different Rubygems,

gem 'handlebars_assets'

and

gem 'ember-rails'  

From what I read, those two gems are supposed to precompile all .hbs files and including the templates directory tree should fix this problem.

What am I missing? Why isn't this working for me?

Thanks.

Answer 1

Did you turn on the Ember support in Handlebars Assets?

HandlebarsAssets::Config.ember = true

This will add the templates to the Ember.TEMPLATES namespace so they can be resolved.
