Yes, you should use an each loop: <ul> {{#each selectedUsers}} <li>{{ this }}</li> {{/each}} </ul> From the docs: You can iterate over a list using the built-in each helper. Inside the block, you can use this to reference the element being iterated over. <ul class=”people_list”> {{#each people}} <li>{{this}}</li> {{/each}} </ul> when used with this context: … Read more
They are all template helpers with the following main characteristics as described in emberjs guides. (http://emberjs.com/guides/templates/rendering-with-helpers/) 1.{{outlet}} – Renders a template based on the route determined by the router. Based on the route the corresponding controller and view are used. This is useful when rendering contents based on the route, which is the most common … Read more
If using mongoose, this issue can be solved by using .lean() to get a json object (instead of a mongoose one): dbName.find({}).lean() // execute query .exec(function(error, body) { //Some code });
Your logic is good, just make some changes to the template <template name=”myTemplate”> {{testHelper “value1” “value2”}} </template> Bare in mind that the testHelper function is only defined in the myTemplate template. If you want to register testHelper globally you’ll need to do something like this Handlebars.registerHelper(‘testHelper’, function(foo, bar){ console.log(foo); console.log(bar); }); Have fun
Just in case anyone stumbles across this question. This functionality exists now in Handlebars. Do this: {{#each items}} {{! Will pass the current item in items to your partial }} {{> item-template this}} {{/each}}
There is a syntax error in the example. The correct syntax is {{@../index}}. We are looking at ways that we can support custom naming of these parameters in future versions of the language so this is easier to deal with. https://github.com/wycats/handlebars.js/issues/907
So after much trial and error (which is the best way to learn it) here’s the way that works for me. First- externalize all your templates, say you have a template inside script tags like <script id=”tmpl_ownevents” type=”text/templates”> {{#unless event}} <div class=”notfoundevents”><p>No events for you</p></div> {{/unless}} </script> Create a new file called events.tmpl and copy/paste … Read more
You can specify what layout you want to use as part of the render call. If you create a new layout called other.hbs, you can then do something like: res.render(‘view’, { title: ‘my other page’, layout: ‘other’ }); To override this for the entire application, you can use: app.set(‘view options’, { layout: ‘other’ });
I know I’m late to the parts but I found a WAYYYY simpler method {{#unless @last}},{{/unless}}
Handlebars gives you the possibility to write a custom helper that handles this situation, e.g. a helper function that lets you perform calculations on expressions like addition and subtraction etc. Below function registers a new helper, which simply increments a value by 1: var Handlebars = require(‘handlebars’); Handlebars.registerHelper(“inc”, function(value, options) { return parseInt(value) + 1; … Read more
