python - Method GET not allowed in DRF ViewSet when trying to retrieve single resource -

i new python , django. have created viewset follows:

api/views.py

class userdetails(viewset): """ create, select, update or delete """  def retrive(self, request, pk):     user = self.get_object(pk)     print(user.query)     user = testserializer(user)     return response(user.data)  def list(self, request):     users = testtb.objects.all()     print(users.query)     serializer = testserializer(users, many=true)     return response(serializer.data)  def create(self, request):     serializer = testserializer(data=request.data)     if serializer.is_valid():         serializer.save()         return response(serializer.data, status=status.http_201_created)     return response(serializer.errors, status=status.http_400_bad_request)  def update(self, request, pk):     user = self.get_object(pk)     serializer = testserializer(user, data=request.data)     if serializer.is_valid():         serializer.save()         return response(serializer.data)     return response(serializer.errors, status=status.http_400_bad_request)  def destroy(self, request, pk):     user = self.get_object(pk)     user.delete()     return response(status=status.http_204_no_content)  def get_object(self, pk):     try:         return testtb.objects.get(pk=pk)     except testtb.doesnotexist:         raise http404 

api/urls.py

router = routers.defaultrouter() router.register(r'users', userdetails, base_name='user-details')  urlpatterns = router.urls 

this works fine post request create new resource, request resources, put request update resource , delete request delete resource. how can retrieve single resource? when make request http://127.0.0.1:8000/api/users/1/ shows error -

{ "detail": "method \"get\" not allowed." }

it means retrieve() method in userdetails never called. know missing something, not able figure out what.

change retrive retrieve. made answer out of comment, suggested @linovia.
