Example of Cooking API using Nested Serializers

Note: When accessing API routers inside browser panel, if you try opening the form to add information, you will see a message as: Lists are not currently supported in HTML input, this is normal normal because Django Rest does not support forms for many to many nested serializers, you should use raw data our 'curl' or 'httpie' instead.

Installation

1. Create your own environment (virtualenv)

        virtualenv -p python3.6 venv
        source venv/bin/activate

1.1 Check your python version and pip requirements:

        python --version #should be 3.6 or greater
        pip install -r requirements.txt

2.0 Create db, make migrations and run the server:

        python manage.py makemigrations
        python manage.py migrate
        python manage.py runserver

2.1 Check your API-Root at localhost:8000
