Rails 4 Active Model Validations

I'm trying to create a Contact Us form on my website using Active Model.

The problem I am having is errors messages are never returned.

I'm using a remote form.

routes:

 resource :front_contacts, only: :create, controller: :front_contact

controller:

 class FrontContactController < ApplicationController
   def create
     contact = FrontContact.new(params[:front_contact])
     @errors = contact.errors.size
   end
 end

front_contact:

 class FrontContact
   include ActiveModel::Model

   attr_accessor :name, :email, :message

   validates_presence_of :name, :message
   validates_format_of :email, with: /[a-zA-Z0-9._%-]+@(?:[a-zA-Z0-9-]+\.)+(com|net|org|info|biz|me|edu|gov)/i
  end

js.erb:

  alert(<%= @errors %>);

The alert is always alerting zero.

Please advise.

If you're using Rails 4, there's the new inclusion of strong params that may be preventing your models from getting created.

Do you have something like the following anywhere in your controller?

params.require(:front_contact).permit!

I had the same problem as you when initially switching over to Rails 4, and was baffled because not permitting specific params doesn't throw an error message; the object just doesn't get created.

If you have a RailsCasts account, there's a really great video on how to deal with strong params here.
