From 0164c328f775e38b16ea21cc64ad953694cd0188 Mon Sep 17 00:00:00 2001 From: lizerk Date: Wed, 11 Mar 2026 16:39:37 +0300 Subject: [PATCH] =?UTF-8?q?refactor(communications):=20=D0=A3=D0=B4=D0=B0?= =?UTF-8?q?=D0=BB=D0=B8=D1=82=D1=8C=20=D0=B7=D0=B0=D0=B2=D0=B8=D1=81=D0=B8?= =?UTF-8?q?=D0=BC=D0=BE=D1=81=D1=82=D1=8C=20=D0=BE=D1=82=20employees=20app?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BREAKING CHANGE: Полная независимость communications модуля Удалено: - Поле Chat.department (FK на employees.Department) - Импорты Department из всех файлов communications - Q(department=...) фильтры в API/WebSocket/rules Перемещено: - Сигнал create_main_department_chat → employees/signals.py (проектоспецифичная логика) Обновлено: - models.py: удалено поле department, constraint, index - api/viewsets.py: использует GenericFK через ContentType.objects.get() - consumers.py: использует GenericFK через ContentType.objects.get() - rules.py: is_department_chat теперь использует get_participants() - admin.py: удален department из list_display/search_fields Миграция: - 0035_remove_department_field.py: удаляет поле, constraint, index Результат: ✅ communications НЕ зависит от employees ✅ System check: 0 errors ✅ Использует только GenericFK (context_object) ✅ Полностью переиспользуемый модуль Для EUSRR-специфичной логики department чатов: -
