Orders API

Instructions to run the code

• git clone https://github.com/sahit12/Orders.git && cd Orders

• source venv/bin/activate

• python order/manage.py runserver

• Paste your data in POSTMAN with the request method being a POST and API as http://127.0.0.1:8000/orders/. Add the data under Body tab. (Example data below)

4. Optional: To check the API with different datasets, I have added test cases. To run it - python order/manage.py test api

Working Examples

1. Example data 1

    "order_items": [
        {
            "name": "bread",
            "quantity": 2,
            "price": 2200
        },
        {
            "name": "butter",
            "quantity": 1,
            "price": 5900
        }
    ],
    "distance": 1200,
    "offer": {
        "offer_type": "FLAT",
        "offer_val": 1000
    }
}

2. Example data 2

    "order_items": [
        {
            "name": "bread",
            "quantity": 2,
            "price": 2200
        },
        {
            "name": "butter",
            "quantity": 1,
            "price": 5900
        }
    ],
    "distance": 1200,
    "offer": {
        "offer_type": "DELIVERY"
    }
}

3. Example data 3

    "order_items": [
        {
            "name": "ice-cream",
            "quantity": 4,
            "price": 10000
        },
        {
            "name": "butter",
            "quantity": 1,
            "price": 6000
        }
    ],
    "distance": 5200,
    "offer": {
        "offer_type": "FLAT",
        "offer_val": 10000
    }
}

Important Technical Decisions

• Technology used for backend: Django-3.2
• To test API: Postman
• Database not used as it was not required.
• Have assumed the request method to be a POST as passing the data content in the request body is safer with POST.
• Django by default use a csrf token for post requests for safety measures. I have removed it for this request to showcase the API easily.
• Not handled the exception case by case for the moment, current scenario doesn't require it, but could be handled better.
• Added the ALLOWED_HOSTS to only localhost callback.
