Since there's currently no good solution in stock Ember-Data, I made my own solution by adding an apiErrors property to DS.Model and then in my RestAdapter subclass (I already needed my own) I added error callbacks to the Ajax calls for createRecord and updateRecord that save the errors and put the model in the "invalid" state, which is supposed to mean client-side or server-side validations failed.

Here's the code snippets:

This can go in application.js or some other top-level file:

DS.Model.reopen({
  // Added for better error handling on create/update
  apiErrors: null
});

This goes in the error callbacks for createRecord and updateRecord in a RestAdapter subclass:

error: function(xhr, textStatus, err) {
    console.log(xhr.responseText);
    errors = null;
    try {
        errors = JSON.parse(xhr.responseText).errors;
    } catch(e){} //ignore parse error
    if(errors) {
        record.set('apiErrors',errors);
    }
    record.send('becameInvalid');
}
