Presto

Task

Create a RESTful API which returns restaurant's dishes and their toppings.

Features

Dependencies

Python 3.5+
Basic Language of the project.
Django + Django Rest Framework
Used to create api services. PsyCopg2
PostgreSQL driver for Python.
DjangoRestFramework-Recursive
Used to create api serializer for Topping model. This library allows to create recursive fields for models.

Tests

Test module contains test cases for all endpoints. It checks both API endpoints status codes and response schema correctness.
You can run test using command python3 manage.py test.

Response Schema

GET /restaurants/

[
    {
        "title": "McDonalds",
        "address": "Pushkina kolotushkina",

    }
]

Django motivation

Django is "Batteries included" framework. It contains all functionality I need except creating RESTful API endpoints, which are created using Django Rest Framework.

DjangoRestFramework-Recursive

In DjangoRestFramework by default I can use DRF-nested serializers to create recursive fields. But unfortunately, depth of those fields is limited so I was forced to use DRF-Recursive which solves this problem.

Quick Start

• Clone repository
• Create database 'presto', with owner admin:admin (You can change DB settings in module settings.py )
• While in project root dir, use command pip3 install -r requirements.txt
• Use command manage.py runserver localhost:8000 to run project server
• (Optionally) You can create superuser via manage.py createsuperuser to access admin panel
• (Optionally) Run tests using manage.py test
