Rails-4 missing dom_id method in cucumber step definition

• OS = CentOS-6.6


• Ruby = 2.0.0


• Rails = 4.2.0


• Cucumber = 3.1.18


• Capybara = 2.4.4

We are moving an existing RoR-3.2 to 4.2. We have added in the necessary gems to ease the pain of many of the deprecations:

  # Temporary gems to get to Rails4
  gem 'protected_attributes'
  gem 'rails-observers'
  gem 'actionpack-page_caching'
  gem 'actionpack-action_caching'
  gem 'activerecord-deprecated_finders'
  gem 'dynamic_form'

However, I am somewhat stymied with this situation involving one of our Cucumber step_definitions:

When /deletes? the "(.*)" correspondent/ do |row|
  this_correspondent = Correspondent.find_by_correspondent_common_name(
              "my correspondent number #{row.hll_words_to_i}")
  within("td#" + dom_id( this_correspondent, :delete )) do
    click_link( "Destroy Correspondent" )
  end
end

Which produces this error:

(::) failed steps (::)

undefined method `dom_id' for
#<Cucumber::Rails::World:0x000000089c92f0> (NoMethodError)
./features/app/models/correspondents/step_definitions
    /correspondent_steps.rb:43:in
`/deletes? the "(.*)" correspondent/'
features/app/models/correspondents/correspondent.feature:68:in
`When they delete the "first" correspondent'

Testing this view code:

  <% for correspondent in @correspondents %>
    <tr id="<%=dom_id(correspondent, :row_1)%>">
      <td><%=h correspondent.correspondent_common_name.titlecase -%></td>
      <td></td>
      <td><%=h correspondent.correspondent_legal_form -%></td>
<!-- See http://ift.tt/1Dl518s -->
<!-- and http://ift.tt/1Dl518s -->
      <td><%= "%06d" % correspondent.id -%></td>
      <td id="<%=dom_id(correspondent, :show)%>"><%= link_to 'Show Correspondent', 
              correspondent -%></td>
      <td id="<%=dom_id(correspondent, :edit)%>"><%= link_to 'Edit Correspondent',
              edit_correspondent_path(correspondent) -%></td>
      <td id="<%=dom_id(correspondent, :delete)%>"><%= link_to 'Destroy Correspondent',
              correspondent, :confirm => 'Are you sure?', :method => :delete -%>
      </td>
    </tr>

The Rails upgrade guide says this:

Rails 4.0 deprecates the dom_id and dom_class methods in controllers (they are fine in views). You will need to include the ActionView::RecordIdentifier module in controllers requiring this feature.

Which I am fine with. I cannot find any occurrence in the existing code base where either method is explicitly used outside of view templates.

However, I am not sure how I am supposed to test for view elements using dom_id() using Cucumber. Is there something I need to add to the development/test gems to get back this behaviour?
