测试Post API接收状态码200而不是201

Question

My test for my post method API receive status code 200 but should 201 I tried to find where is problem but i couldn't. It would be easier if i would get error status 4xx but i have no idea why post method could receive code 200. My API view works fine so this must be problem with test code but I really don't have idea what may cause this problem. Maybe I'm wrong and status code 200 is ok, but I think that post method should receive status 201.

test_api.py

def test_post_logged_in(self):
    product = Product.objects.get(id=1)
    self.client.login(username='test', password='test123')
    data = {
        'nick': self.user.id,
        'rate': '1/5',
        'content': 'here is comment',
        'product': product.id
    }
    response = self.client.post(reverse('add_comments', kwargs={'id': product.id}), data, format='json')
    self.assertEqual(response.status_code, 201, f'expected Response code 201, instead get {response.status_code}')

views.py

class CreateComment(APIView):

def get_object(self, id):
    try:
        return Product.objects.get(id=id)
    except Product.DoesNotExist:
        raise Http404

def get(self,request,  id):
    product = self.get_object(id)
    serializer = ProductSerializer(product)
    return Response(serializer.data)

def post(self, request,id):
    serializer = CommentSerializer(data=request.data)
    if serializer.is_valid():
        serializer.save(nick=request.user, product=self.get_object(id))
        return Response(serializer.data)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

In your post() , you need to return status.HTTP_201_CREATED if successful.

Try this:

def post(self, request,id):
    serializer = CommentSerializer(data=request.data)
    if serializer.is_valid():
        serializer.save(nick=request.user, product=self.get_object(id))
        return Response(serializer.data, status=status.HTTP_201_CREATED)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
