Site Prism: after creating Sections I get a Rack::File argument error deep in the gem code, am I using this wrong?

Question

I get this error when attempting to run cucumber when the site_prism page model is using sections. I had done a simpler page without sections that worked just fine.

Rack::File headers parameter replaces cache_control after Rack 1.5. You should provide section class either as a block, or as the second argument (ArgumentError)

Site Prism page model:

class TestUIPage < SitePrism::Page
  set_url Rails.application.routes.url_helpers.documents_retrieve_path
  set_url_matcher /Rails.application.routes.url_helpers.documents_retrieve_path/
  section :validation, 'div#collapseFifteen'
  section :document_set, 'div#collapseFour'
end

class DocumentSetSection < SitePrism::Section
  element :root, 'input#root'
  element :extension, 'input#extension'
  element :submit_button, 'button'
end

class ValidationSection < SitePrism::Section
  element :patient_root, 'input#patient_root'
  element :patient_extension, 'input#patient_extension'
  element :patient_first_name, 'input#patient_first_name'
  element :patient_gender, 'input#patient_gender'
  element :patient_birth_date, 'input#patient_birth_date'
  element :validate_button, 'button#validate_patient_demographics'
end

Answer 1

You left out the model in your section. Here's what you want:

class TestUIPage < SitePrism::Page
  set_url Rails.application.routes.url_helpers.documents_retrieve_path
  set_url_matcher /Rails.application.routes.url_helpers.documents_retrieve_path/
  section :validation, ValidationSection, 'div#collapseFifteen'
  section :document_set, DocumentSetSection, 'div#collapseFour'
end
