I just started learning Ember.js (bought the PeepCode screencast), and am learning quite smoothly from it, but ran into a problem when trying to write my first Ember app.
Force Ember to use the model hook; just pass the id instead of the object:
{{#link-to 'place' place.id}} {{place.name}} {{/link-to}}
As Ember no longer knows which object is related to given id, Ember will call the model hook (and so the data will be loaded from the server).
