[FIXED] DRF - Request unique identifier

Issue

Is there any unique identifier like uuid in request object?

from rest_framework.decorators import api_view
from rest_framework.responses import Response


@api_view(['GET'])
def index_view(request):
    return Response()

I need a unique identifier for each request to use it further.

If there is not where to add it? Into request.META?

Solution

This is not given by default, but you can always create a middleware to add the uuid into each request. request.META is a good place to add it since it's a common place to add a property related to a request.

Here is an example code.

# ~/apps/core/middleware.py
# Place this file wherever you feel most suitable for your project.

import uuid


class SimpleMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        request.META["uuid"] = uuid.uuid4()
        return self.get_response(request)

Then, on settings, you can add the middleware.

MIDDLEWARE = [
    ...
    "apps.core.middleware.SimpleMiddleware"
]

You can test using your code above.

from rest_framework.decorators import api_view
from rest_framework.responses import Response


@api_view(['GET'])
def index_view(request):
    print(request.META.get('uuid')) # try to print here to check
    return Response()
