Task

The objective of this code challenge is to develop a backend service or api that returns json over http. We would like to have a CRUD (create, read, update, delete) on restaurant objects. A restaurant object will have the following fields:

• id: int
• name: string
• opens_at: time
• closes_at: time

For example, a call to the system could be something like:

GET /restaurant/1

And the output would be { "id": 1, "name": "Pizza Berlin", ... }

Project info

• Python 3.6
• Django 1.11 LTS
• GraphQL
• Factories (factory boy) to create init data

Deploy

• install and activate virtual environment(virtualenv -p python3.6 venv)
• pip install -r requirements.txt
• python manage.py migrate
• python manage.py runserver

OR

• install and activate virtual environment(virtualenv -p python3.6 venv)
• use make file (make <command>). Use make help for help

Use

• Get restaurant by ID: /restaurant/<id>
• Delete restaurant: send DELETE request to url /restaurant/ with JSON data {id: <restaurant_id>}
• Create restaurant: use graphql (url /graphql/). Request example:

mutation{
  createRestaurant(restaurantData: {name: "TestGraphQl", opensAt: "01:00:00", closesAt:"23:00:00"})
  {
    ok
    message
    restaurant {
      id
      name
      opensAt
      closesAt
    }
  }
}

• Update restaurant: use graphql (url /graphql/). ID is a must input, other fields are optional. Request example:

mutation{
  updateRestaurant(restaurantUpdateData: {id: 2, name: "New Name 2", opensAt:"23:59"}){
    ok
    message
    restaurant {
      name
      opensAt
      closesAt
    }
  }
}

• Get all restaurants (additional option). Use graphql. Request example:

query{
  getAllRestaurants {
    id
    name
    opensAt
    closesAt
  }
}
