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, "test" %>
  <%= f.submit %>
<% end %>

But then I get this error:

undefined method `merge' for "test":String

How can I pass values in my hidden_field in rails?

ruby-on-rails ruby ruby-on-rails-3 forms hidden-field

It works fine in Ruby 1.9 & rails 4

<%= f.hidden_field :service, value: "test" %>

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')
