POST, PUT, DELETE in Django RESTful framework not working - django

Question

I'd like to post to my Django server using POST so I can add a employee item.
views.py
class EmployeeList(generics.ListAPIView):
queryset = Employee.objects.all()
serializer_class = EmployeeSerializer
class EmployeeDetail(generics.RetrieveUpdateDestroyAPIView):
queryset = Employee.objects.all()
serializer_class = EmployeeSerializer
models.py
class Employee(models.Model):
firstname=models.CharField(max_length=10)
lastname=models.CharField(max_length=10)
emp_id=models.IntegerField()
def __str__(self):
return self.firstname;
serializer.py
class EmployeeSerializer(serializers.ModelSerializer):
class Meta:
model=Employee
# fields={'firstname','lastname'}
fields='__all__'
My POST request:
{
"id": 8,
"firstname": "zxcvb",
"lastname": "bnmmm",
"emp_id": 3
}
Error I got:
{
"detail": "Method \"POST\" not allowed."
}
Even after using generics.RetrieveUpdateDestroyAPIView I can't POST, PUT or DELETE.
PS: I’m new to Django REST framework.

To provide a post method handler you'll need a view with a create() action (CreateAPIView or ListCreateAPIView). Check the documention about concrete view classes.
Change your EmployeeList view to inherit from ListCreateAPIView for add read-write endpoints to represent a collection of employees
class EmployeeList(generics.ListCreateAPIView):
queryset = Employee.objects.all()
serializer_class = EmployeeSerializer
Now, just register the views with the URL conf as usual
urlpatterns = [
path('employees/', EmployeeList, name='employee-list'),
path('employees/<int:pk>/', EmployeeDetail, name='employee-detail'),
]
Concrete view classes map methods defined in mixins such ListModelMixin, CreateModelMixin, RetrieveModelMixin, etc. to HTTP methods. By defaults, theese actions (see here) are mapped to the following HTTP methods
list - get
create - post
retrieve - get
update - put
partial_update - patch
destroy - delete
