Ruby on Rails的Ajax错误处理

Question

我入门到Ajax和红宝石和我的问题是，我不能得到错误信息，当我与刷新

控制器

class InvitesController < ApplicationController 

    def request_invite 
     render_404 unless request.xhr? 

     @invitation = Invite.new(params[:invite]) 
     if @invitation.save 
      @return = { :error => false, :response => "OK" } 
     else 
      @return = { :error => true, :response => "BAD" } 
     end 
     render :json => ActiveSupport::JSON.encode(@return) 
    end 

end 

通过后提交表单我能得到

所以现在我有自定义错误，但我想，以取代“BAD”与实际的错误，形式回报...

模型

class Invite < ActiveRecord::Base 

    validates :email, :presence => true, :uniqueness => true 

    validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i 

end 

我该怎么做？

尝试这样：

@return = { :error => true, :response => @invitation.errors.full_messages.join(", ") }
