Sorry I’m a little late in the game here. The accepted answer is great but I wanted to add an answer that I think is also useful, especially if you are iterating over simple row/column arrays. When you’re working with nested handlebar paths, you can use ../ to refer to the parent template context (see … Read more
Use @root. This is in handlebars-v2.0.0.js {{@root.somthing.nested_somthing}}
From http://handlebarsjs.com/ Handlebars HTML-escapes values returned by a {{expression}}. If you don’t want Handlebars to escape a value, use the “triple-stash”. {{{expression}}}
This video explains the concepts: http://www.eventedmind.com/posts/meteor-spark-data-annotation-and-data-contexts. The direct answer to your question: The thisArg inside an event handler should point to a data context. But sometimes the data context is undefined. When you use the Function.prototype.call(thisArg, …) in JavaScript, if the thisArg is undefined (e.g. a dataContext is undefined) the browser will set this equal … Read more

Dependencies are up-to date and current npm version is 3.0.0. Last update 29 days ago (at the moment of this post) One important … Read more
Your first solution is possible, AngularJS allow to change the start/end symbols of text interpolation like this: appModule.config(function($interpolateProvider) { $interpolateProvider.startSymbol(‘{[{‘); $interpolateProvider.endSymbol(‘}]}’); }); Then you could use it in your template: <div>{[{message}]}</div> Also see: $interpolateProvider documentation Hope this helps.
The easiest thing would be to add a custom if_eq helper: Handlebars.registerHelper(‘if_eq’, function(a, b, opts) { if(a == b) // Or === depending on your needs return opts.fn(this); else return opts.inverse(this); }); and then adjust your template: {{#if_eq this “some message”}} … {{else}} … {{/if_eq}} Demo: http://jsfiddle.net/ambiguous/d4adQ/ If your errors entries weren’t simple strings then … Read more
The solution is quite simple, and maybe someone will find it useful. In most projects you have a couple of date formats you want to use. So it’s a good approach to define your formats with readable names. For this example I took just ‘short’ and ‘long’, but you will see, it’s very easy to … Read more
UPDATE Since this PR, it’s now possible to use the each helper with index, taking advance of the new block params syntax. This is available on canary and hopefully will be enabled by default in ember 1.11 {{#each model as |item index|}} <li> Index: {{index}} Content: {{item}} </li> {{/each}} Live sample FOR OLD VERSIONS You … Read more
