It's important to make sure your server-side app is secure when using a client-side application like Ember, since any user can alter your javascript at runtime to make it do whatever you want. Therefore you want to make sure you still use server-side validations to make sure that your persistant records are valid.

However, Ember doesn't include any built-in way of displaying these errors on a form like you might be used to coming from a Rails world. This is how I do it.

Let's take this login form as an example (using twitter bootstrap css):

<form class="form-horizontal" {{action sendRegistration on="submit"}}>
  <div class="control-group">
    <label class="control-label" for="email">Email</label>
