I'm trying to create a custom API (not using models), but its not showing the request definition in the schema (in consequence, not showing it in swagger). My current code is:

views.py

class InfoViewSet(viewsets.ViewSet):@list_route(methods=['POST'])def some_method(self, request):data = JSONParser().parse(request)serializer = GetInfoSerializer(data=data)serializer.is_valid(raise_exception=True)info = get_data_from_elsewhere(serializer.data)return Response(info)

urls.py

router.register(r'^info', InfoViewSet, base_name='info')

serializers.py

class InfoSomeMethodSerializer(serializers.Serializer):list_id = serializers.ListField(child=serializers.IntegerField())password = serializers.CharField()

And it appears in swagger, but just the response part. How can I register the post parameters? I'm also not sure if I'm using DRF correctly (I'm new) so any correction will be appreciated.

edit: I tried the serializer_class argument suggested by Linovia and didn't work, I got:

TypeError: InfoViewSet() received an invalid keyword 'serializer_class'

I tried overriding get_serializer_class method and didn't work either:

def get_serializer_class(self):if self.action == 'some_method':return InfoSomeMethodSerializer

For people running this into the future - when you add the serializer_class attribute to the @action decorator of a view which inherits from viewsets.ViewSet, it will indeed by default give you a TyperError, as OP mentioned:

TypeError: InfoViewSet() received an invalid keyword 'serializer_class'

To overcome this, simply add serializer_class = None as a class variable to your view.

Example of editing OPs code:

class InfoViewSet(viewsets.ViewSet):# ↓ ADD THIS!serializer_class = None # Now you can add serializer_class without geting a TypeError ↓@list_route(methods=['POST'], serializer_class=GetInfoSerializer)def some_method(self, request):data = JSONParser().parse(request)serializer = GetInfoSerializer(data=data)serializer.is_valid(raise_exception=True)info = get_data_from_elsewhere(serializer.data)return Response(info)
