From dca1c1f20de40c4725ade753598e3b88634a9232 Mon Sep 17 00:00:00 2001 From: Bernardo Anderson Date: Mon, 18 Aug 2025 16:29:22 -0500 Subject: [PATCH 01/11] 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
