From dca1c1f20de40c4725ade753598e3b88634a9232 Mon Sep 17 00:00:00 2001 From: Bernardo Anderson Date: Mon, 18 Aug 2025 16:29:22 -0500 Subject: [PATCH] CP-10361 - Add ATS integration for automatic form prefill values Add support for fetching prefill values from ATS system when task_assignment_id parameter is provided. This includes: - New ATS API integration in PrefillFieldsHelper to fetch prefill values - Cache layer for ATS prefill values with 30-minute TTL - Merge logic to respect existing submitter values over ATS prefill values - Error handling and logging for ATS API failures - Integration with SubmitFormController to fetch values before form rendering The feature allows forms to be pre-populated with candidate data from the ATS system while preserving any values already entered by submitters. --- app/controllers/submit_form_controller.rb | 17 ++++ app/helpers/prefill_fields_helper.rb | 103 ++++++++++++++++++++++ app/views/submit_form/show.html.erb | 3 +- 3 files changed, 122 insertions(+), 1 deletion(-) diff --git a/app/controllers/submit_form_controller.rb b/app/controllers/submit_form_controller.rb index 24092dcc..9fdc9a0f 100644 --- a/app/controllers/submit_form_controller.rb +++ b/app/controllers/submit_form_controller.rb @@ -1,6 +1,8 @@ # frozen_string_literal: true class SubmitFormController < ApplicationController + include PrefillFieldsHelper + layout 'form' around_action :with_browser_locale, only: %i[show completed success] @@ -28,6 +30,9 @@ class SubmitFormController < ApplicationController Submitters::MaybeUpdateDefaultValues.call(@submitter, current_user) + # Fetch ATS prefill values if task_assignment_id is provided + @ats_prefill_values = fetch_ats_prefill_values_if_available + @attachments_index = build_attachments_index(submission) return unless @form_configs[:prefill_signature] @@ -98,4 +103,16 @@ class SubmitFormController < ApplicationController ActiveStorage::Attachment.where(record: submission.submitters, name: :attachments) .preload(:blob).index_by(&:uuid) end + + def fetch_ats_prefill_values_if_available + task_assignment_id = params[:task_assignment_id] + return {} if task_assignment_id.blank?
