csrf cookie not set django rest - django

Question

When working on REST browsable API the responses work fine but when I started working on postman to integrate with front end on the other side the respond become:
{
"detail": "CSRF Failed: CSRF cookie not set."
}
I tried everything to solve this error but nothing change, and checked every question here on CSRF token but still didn't work
These are my codes:
views.py:
from django.shortcuts import render
from django.http import JsonResponse
from rest_framework.response import Response
from rest_framework import status
from User.serializers import UserDataSerializer, ImageSerializer
from rest_framework.views import APIView

from django.contrib.auth.models import User
from django.contrib.auth import authenticate, login, logout
from rest_framework.renderers import TemplateHTMLRenderer
from django.views.decorators.csrf import csrf_exempt
#csrf_exempt
class Signup(APIView):
def post(self, request, format = None):
serializer = UserDataSerializer(data = request.data)
if(serializer.is_valid()):
user = User.objects.create_user(
username = serializer.data['username'],
first_name = serializer.data['first_name'],
last_name = serializer.data['last_name'],
email = serializer.data['email'],
password = serializer.data['password'],
)
#add the name because it is not with create_user method
# user.name = serializer.data['name']
# user.save()
login(request, user)
print ("logged")
text = {'valid' : True , 'errors' :"ur password"+serializer.data['password']}
return JsonResponse(serializer.data)
else:
return JsonResponse(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
class Login(APIView):
def post(self, request):
username = request.data.get('username')
password = request.data.get('password')
user = authenticate(username=username, password=password)
if user is not None:
login(request, user)
serializer = UserDataSerializer(user)
return JsonResponse(serializer.data, status=status.HTTP_302_FOUND)
else:
text = {'valid' : False , 'errors' : "Invalid Username or Password"}
return Response(text, status=status.HTTP_401_UNAUTHORIZED)
class Logout(APIView):
def get(self, request):
logout(request)
return Response({"valid": True}, status=status.HTTP_200_OK)
class ImageUpload(generics.CreateAPIView):
queryset = Image.objects.all()
serializer_class = ImageSerializer

Answer 1

you have to use ensure_csrf_cookie decorator in the urls like this
from django.views.decorators.csrf import ensure_csrf_cookie
urlpatterns = [
url(r'^login/?$', ensure_csrf_cookie(views.Login().as_view())),
]
Also you need to add all of your CORS settings
