How to set up and validate locally

  1. Enable the feature flag in Rails console Feature.enable(:geo_primary_verification_view);
  2. Test the new API endpoint as an admin user:
# Replace YOUR_ADMIN_TOKEN with an actual admin personal access token
curl -H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
     "http://localhost:3000/api/v4/admin/data_management/lfs_object/1"
  1. Verify the response contains the expected fields:
  • id, model_class, created_at
  • Geo verification fields: checksum, checksum_state, checksum_retry_count, etc.
  • addl_info with additional model attributes
  1. Test with different model names:
curl -H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
     "http://localhost:3000/api/v4/admin/data_management/snippet_repository/1"
  1. Test with different model IDs:
curl -H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
     "http://localhost:3000/api/v4/admin/data_management/snippet_repository/20"
