 # CR_python1
-Task 1
+
+Реализовать простой сервис, который принимает и отвечает на HTTP-запросы
+###Запуск в dev-окружении
+Запуск develop-сервера
+
+`docker-compose up`
+
+Инициализация базы данных(применение миграций)
+
+`docker-compose exec web python3 manage.py migrate`
+
+Создание суперпользователя:
+
+`docker-compose exec web python3 manage.py createsuperuser`
+
+Для того чтобы авторизоваться нужно зайти на http://localhost:8000/admin
+
+API находится на http://localhost:8000/api
+
+Создание фейковых данных:
+
+`docker-compose exec web python3 manage.py createmockdata`
+
+
+Запуск тестов:
+
+`docker-compose exec web python3 manage.py test --keepdb`
+
+###Описание
+####Функциональность
+* Получение всех городов из базы данных (использовать mock-данные)
+* Получение всех улиц города из базы данных (использовать mock-данные)
+* Создать магазин с данными о городе, улице, графике работы (по дням и по часам) и примечание
+* Получить магазин/(-ы) на основе фильтрации по одному или нескольким аттрибутов у сущности магазина (см. предыдущий пункт)
+
+####Инструменты
+* Python 3.6+
+* Django 2.2+
+* Django REST Framework 
+* Реляционная база данных (желательно – PostgreSQL)
+
+
+####Условия
+* Наличие README.md для описания проекта и способа его установки/запуска локально
+* Работа с Docker будет большим плюсом
+* Обратить внимание на проектирование таблиц базы данных. Вероятно, здесь будет не одна таблица и будут применимы внешние ключи (Foreign Key).
