From 179e2e407d225c6ff3d05dc97cfc90902020719a Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Fri, 1 Aug 2025 17:12:47 -0500 Subject: [PATCH] fix: Convert telemetry_seq string values to integers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The APRS parser returns telemetry sequence numbers as strings (e.g., "094"), but the database schema expects integers. This was causing Ecto.ChangeError in production when processing telemetry packets. Changes: - Updated put_telemetry_fields/2 to convert string seq values to integers - Added comprehensive tests for telemetry_seq type conversion - Handles nil, string, integer, and invalid seq values gracefully Production deployment notes: 1. Check if migration 20250801215236 has run in production 2. If not, run pending migrations before deploying this fix 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- lib/aprsme/packet.ex | 21 +- test/aprsme/packet_test.exs | 68 +++ test/aprsme/packets_test.exs | 775 +++++++++++++++++++++++++++++++++++ 3 files changed, 863 insertions(+), 1 deletion(-) create mode 100644 test/aprsme/packets_test.exs diff --git a/lib/aprsme/packet.ex b/lib/aprsme/packet.ex index bc10e3a..bd288d1 100644 --- a/lib/aprsme/packet.ex +++ b/lib/aprsme/packet.ex @@ -435,8 +435,27 @@ defmodule Aprsme.Packet do #
