From 1b4b7f1773ab6f162949427caeace6a5d5475d3d Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Sun, 18 Jan 2026 10:51:11 -0600 Subject: [PATCH] fix user deletion bug and implement timezone support User deletion bug: - Store client IP in socket assigns during mount - Access stored IP during delete event instead of connect_info - Fixes RuntimeError when attempting to delete users Timezone support: - Add timezone offset maps for common timezones (no external deps) - Implement shift_timezone/2 helper using DateTime.add/3 - Add timezone-aware format_datetime/2, format_date/2, format_iso8601/2 - Keep backwards-compatible 1-arity versions defaulting to UTC - Add comprehensive test coverage for timezone conversions - All tests passing (23 tests, 0 failures) Note: Timezone offsets are standard time only (no DST handling) Common timezones supported: America/New_York, America/Los_Angeles, Europe/London, Europe/Paris, Asia/Tokyo, Asia/Shanghai, Australia/Sydney --- lib/towerops_web/helpers/time_helpers.ex | 100 +++++++++++-- .../live/admin/user_live/index.ex | 6 +- mix.lock | 1 + .../helpers/time_helpers_test.exs | 139 ++++++++++++++++++ 4 files changed, 229 insertions(+), 17 deletions(-) create mode 100644 test/towerops_web/helpers/time_helpers_test.exs diff --git a/lib/towerops_web/helpers/time_helpers.ex b/lib/towerops_web/helpers/time_helpers.ex index 02d94f87..1e2ec7d7 100644 --- a/lib/towerops_web/helpers/time_helpers.ex +++ b/lib/towerops_web/helpers/time_helpers.ex @@ -1,8 +1,54 @@ defmodule ToweropsWeb.TimeHelpers do @moduledoc """ - Helper functions for formatting time and date values. + Helper functions for formatting time and date values with timezone support.
