Ember.js: Handlebars no muestra nada (1)
/app.js
var Welcome = Ember.Application.create({});
Welcome.person = Ember.View.extend({
personName: ''Andrew''
});
Aquí está el contenido de index.html, parte de la vista:
/index.html

Mi pregunta es por qué no muestra nada? ¿No debería representar el contenido de personName ?
ACTUALIZAR:
Estoy usando el Starter Kit de Ember. Ya tiene una vista definida. Acabo de agregar una propiedad más al objeto pero todavía no está visible para la vista.
App.MyView = Em.View.extend({
mouseDown: function() {
window.alert("hello world!");
},
name: ''Andrew''
});
Y la parte de vista en .html es:
<script type="text/x-handlebars">
{{#view App.MyView}}
<h1>Hello world {{name}}!</h1>
{{/view}}
</script>
Dado que el evento funciona, ¿no se supone que el nombre es accesible?
Desde 1.0, las vistas preservan su contexto.
VIEW CONTEXT CHANGES
In apps built on earlier version of Ember (before 1.0), the {{#view}} helper
created a new context for the view. This meant that you had to explicitly set the
context on them.
In 1.0, we''ve made this a bit simpler. The {{#view}} helper no longer changes
the context, instead maintaining the parent context by default. Alternatively,
we will use the controller property if provided. You may also choose to directly
overridethe context property. The order is as follows:
Specified controller
Supplied context (usually by Handlebars)
parentView''s context (for a child of a ContainerView)
In the event that you do need to directly refer to a property on the view, you
can use the view keyword, i.e. {{view.myProp}}.
So, for your example, tou have to use {{view.name}}
<script type="text/x-handlebars">
{{#view App.MyView}}
<h1>Hello world {{view.name}}!</h1>
{{/view}}
</script>
