handlebars.js

Handlebars.js has some weird behavior. It renders a boolean with a value of true as the string "true", but a value of false as "". var booleanTestTrue = true; var booleanTestFalse = false; Template: True: {{booleanTestTrue}} False: {{booleanTestFalse}} Renders to: True: true False: (empty string) Is there any way to fix this problem? Or do I have to write a helper? Aaks20 You can use a simple block helper and implement #if like the following: {{#if isTrue}} true {{else}} false {{/if}} If you want to print a string, you should pass a string. false.toString(); Otherwise, yeah you would need a

Hi am New to Handlebarsjs. I have a collection of contacts with name, email, phone, etc. as below [ { "name": "Bob Wolmer", "email": "bob@wolmer.com", "phone": "(535) 235-1234", "address": "301 Cobblestone Wy., Berdrock 00000", "contactId": "1121", "labels": {} }, { "name": "Wilma Erra", "email": "wilma@erra.com", "phone": "(535) 235-3659", "address": "301 Cobblestone Wy., Berdrock 70777", "contactId": "1122", "labels": {} }, { "name": "Brad", "email": "brad@brad.com", "phone": "(535) 235-3546", "address": "301 Cobblestone Wy., Redrock 70777", "contactId": "1123", "labels": [{"name": "Friends"

All assemble users who uses layouts knows that "{{> body }}" marks the point of insertion of contents of any page who uses the layout. But is it possible to define multiple points of insertions, instead of tossing everything at where the {{> body }} is? For instance, in my page I would like to define a specific piece of javascript, but I like that custom javascript to be at the very bottom of the page along with out javascript tags. If it only puts everything where the {{> body }} is, this is not possible, since the script will just be appended to the content. In other words, it would be

I've got a pretty simple handlebars helper file in helpers/handlebars.js : var hbs = require('express-handlebars'); hbs.registerHelper("inc", function(value, options) { return parseInt(value) + 1; }); However, as expected, I can't refer to the {{#inc}} helper because I didn't pass it into the res.render() function. Is there a way to make all helpers in my file global and "auto-included"? edit: After trying @1cgonza's awesome answer, I get: hbs.registerHelper("inc", function(value, options) { ^ TypeError: undefined is not a function When running the app. Here's the app.js : var engine = require

I would like to access the calculated fields I have implemented in the model (backbone.js) from the template. Do I need always to define a helper to do it? I think the problem has to do with the way I pass the model to the template. If I pass this.model.toJSON() I have access to the properties but not to the functions I have defined in it. If I pass this.model directly I can access the function but not the properties of the backbone model. Always pass this.model.toJSON() to your templates. What you need to do to get your calculated values, is override your toJSON method on your model. MyModel

I have a controller object that's like: MyApp.objController = Ember.ArrayController.create({ init: function(data) { data.isValid = function() { return (data.validity === "valid"); } this.pushObject(MyApp.MyObj.create(data)); } }); My view is like: {{#each MyApp.objController}} {{#if isValid}} <some markup> {{else}} <some other markup> {{/if}} {{/each}} I was assuming that the if conditional in Handlebars accepts both values and functions, but this doesn't seem to be the case. Is it actually possible, and I'm just doing it wrong? If you define your isValid as a property , you can use it in your
