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>

	require 'webrat'
	require 'webrat/core/matchers'
	include Webrat::Methods
	include Webrat::Matchers

	Webrat.configure do \|config\|
	config.mode = :mechanize
	end

	class MechanizeWorld < Webrat::MechanizeSession

	NSError* error;
	if(![managedObjectContext save:&error]) {
	NSLog(@"Failed to save to data store: %@", [error localizedDescription]);
	NSArray* detailedErrors = [[error userInfo] objectForKey:NSDetailedErrorsKey];
	if(detailedErrors != nil && [detailedErrors count] > 0) {
	for(NSError* detailedError in detailedErrors) {
	NSLog(@" DetailedError: %@", [detailedError userInfo]);
	}
	}
	else {

	cellForRowAtIndexPath:(NSIndexPath *)indexPath {
	for (int y=0; y<[selectedMonsters count];y++) {
	if [[selectedMonsters objectAtIndex:y] isKindOfTemplate:[monsters objectAtIndexPath:indexPath]] {
	cell.detailLabel.text = [monster quantity];
	}
	else {
	cell.detailLabel.text = "";
	}
	}
	}

	wrapText = (elementID, openTag, closeTag) ->
	textArea = $("##{elementID}")
	len = textArea.val().length
	start = textArea[0].selectionStart()
	end = textArea[0].selectionEnd()
	selectedText = textArea.val().substring(start, end)
	replacement = "#{openTag}#{selectedText}#{closeTag}"
	textArea.val(textArea.val().substring(0, start) + replacement + textArea.val().substring(end, len))

	#example click function

	class Post
	has_one :avatar
	end

	class Avatar
	belongs_to :post
	has_one :image
	delegate :image, :to => :post
	end

	class Combinations
	attr_accessor :number_of_variables

	def initialize(number_of_variables=2)
	@number_of_variables = number_of_variables
	end

	def print_combinations
	combinations.each do \|row\|
	row.each_with_index do \|v, i\|

	unless self.column_names.include? "new_name"
	alias_attribute :new_name, :old_name
	end
