Send 2nd value to AJAX, Rails 4

I have built simple payment system. A part from system is autorize user to create advertisement, but before it can happen user has to fill in text field simple confirmation code. Code is from SMS.

I added AJAX blur so when focus is lost application would check if confirmation code is valid.

So far I have like this:

In SMS controller:

@token = ('0'..'9').to_a.shuffle.first(5).join
@payment.token_salt = BCrypt::Engine.generate_salt
@payment.token_hash = BCrypt::Engine.hash_secret(@token,  @payment.token_salt)

I am not saving token as plain text, I am saving just salt and hash as security precaution. It works great.

In Advertisement controller:

def checktoken

      @payment =   Payment.where('identifier = ?', params[:identifier])
         if @payment.present?
              if @payment.token_hash == BCrypt::Engine.hash_secret(params[:token], @payment.token_salt)
                render :nothing => true, :status => 200
              else
                   render :nothing => true, :status => 409
              end
         else
               render :nothing => true, :status => 409
          end
       return
    end

This method would find required advertisement by identifier and then check if given token hash is the same as in database. So I need 2 values to get to work this code. params[:token] and params [:identifier]

I managed to send first one:

In form:

  <% text_field(:identifier,:value=> @advertisement.identifier, :'data-validate' => '/advertisements/checktoken')  %>

     <%= text_field(:token,:placeholder=> "Kods *" ,:'data-validate' => '/advertisements/checktoken')  %>

In routes.rb

collection do
     get 'checktoken'
  end

My script:

$(document).ready(function(){
    $('[data-validate]').blur(function() {
        $this = $(this);
        $.get($this.data('validate'), {
            token: $this.val()
        }).success(function() {
            $this.removeClass('field_with_errors');
        }).error(function() {
            $this.addClass('field_with_errors');
        });
    });
});

Question is how to pass @advertisement.identifier variable value in the same maner as I am doing with token ?

I googled for this, but there wasn't valid examples just how to do with single value.

Any help would be great. Thanks

You could set id attribute on those fields and you can use it later as selector.

In your view:

<%= text_field(
      :identifier,
      :value => @advertisement.identifier,
      :'data-validate' => '/advertisements/checktoken',
      :id => 'identifier_field'
) %>
<%= text_field(
      :token,
      :placeholder => "Kods *",
      :'data-validate' => '/advertisements/checktoken'
      :id => 'token_field'
) %>

In your javascript code:

$(document).ready(function(){
  $('[data-validate]').blur(function() {
    $this = $(this);
    $.get($this.data('validate'), {
      token: $('#token_field').val(),
      identifier: $('#identifier_field').val()
    }).success(function() {
      $this.removeClass('field_with_errors');
    }).error(function() {
      $this.addClass('field_with_errors');
    });
  });
});
