    'djangopollapp.middleware.PollMiddleware',
]

Testing the Setup

Example superuser authentication:

curl -X POST -d "username=<username>&password=<password>" http://127.0.0.1:8000/api-token-auth/

# Response from DRF
{"token":"dfaef188d5f075802cf7b627a41e4dd3632d127b"}%  

After that we can create poll without questions:

curl -X POST -H "Authorization: Token <token>" 
-H "Content-Type: application/json" 
-d '{"poll":
        {
            "title":"Sample",
            "end_date":"2021-05-13T21:25:46Z",
            "description":"sample discript"
        }
    }' http://127.0.0.1:8000/api-polls/v1/polls/

Documentation

For clients

Unique ID

At the first request to the resource, the middleware checks for a unique id in its cookies. If the id is not found, the middleware generates a unique id in the format "uu id" and gives the guest user a cookie, after which all requests are made with the context of a unique id

Polls

Create

A poll is created in two parts:

• Poll data
• Question data

Each question has its own type.

• 1 - Text answer
• 2 - Single Choice
• 3 - Multi Choice

If question type is 1(Text answer), choices field must be empty. If question type is 2(Single Choice) or 3(Multi Choice), choices field will be a include choice objects

In the data of each question, we also put choices depending on its type

curl http://127.0.0.1:8000/api-polls/v1/polls/ \
-X POST \
-H "Authorization: Token dfaef188d5f075802cf7b627a41e4dd3632d127b" \
-d '{
  "poll": {
    "title": "One more poll",
    "end_date": "2021-05-13T21:25:46Z",
    "description": "some description for this poll",
  },
  "questions": [
    ...
    {
      "qns": "what the fuck?",
      "qns_type": 1,
      "choices": [
        ...
        {
