Some suggestions on the Ruby on Rails view _ruby topics

Do not call the model layer directly from the view.
Do not construct complex formats in the view, and output them to a method or model of the view helper.
Use partial templates and layouts to reduce duplicate code.

Join the client side validation to the usual validators. The steps to do are:

Declares a custom validator from Clientsidevalidations::middleware::base.

 Module Clientsidevalidations::middleware
   class Email < Base
   def response
    if request.params[:email] =~/ ^ ([^@\s]+) @ ((?: [-a-z0-9]+\.) +[a-z]{2,}) $/i
    self.status =/
    else
    self.status = 404
    End
    Super
  end End

Create a new file Public/javascripts/rails.validations.custom.js.coffee and add a reference to it in your Application.js.coffee file:

  
  # App/assets/javascripts/application.js.coffee
  #= require Rails.validations.custom

Add your client validator:

  #public/javascripts/rails.validations.custom.js.coffee
  clientsidevalidations.validators.remote[' email '] = ( element, options)->
   if $.ajax ({
   URL: '/validators/email.json ',
   data: {email:element.val ()},
   Async:false
   }). status = = 404 return
   options.message | | ' Invalid e-mail format '
