DRF Permissions

[Suraj Thapa FC]

In DRF, only AllowAny permission is working.....

My Views.py

class generate_course(APIView) :

         .

         .

         .

         permission_classes = (IsAuthenticated,)

         authentication_classes = (JSONWebTokenAuthentication,)

         def post ( self,  request) :

               ....

              .....

             ....

I also define the setting.py. And also given the token in headers

The postman giving the error

{

detail : Authentication credential were not provided. 

}
