Rails hidden field undefined method 'merge' error

Question

I wanna do something like this in rails

Here is what I have so far in rails:

<%= form_for @order do |f| %>
  <%= f.hidden_field :service,          


        

Answer 1

By the way, I don't use hidden fields to send data from server to browser. Data attributes are awesome. You can do

<%= form_for @order, 'data-service' => 'test' do |f| %>

And then get attribute value with jquery

$('form').data('service')
