Answer 1

You do not need the get_queryset method you could do something like this:

#views.py
class AlertCreateView(ListCreateAPIView):
     queryset = Alert.objects.all()
     serializer_class = AlertSerializer
     permission_classes = (IsAuthenticated,)

Name the queues field in the serializer in the same way as it is written in therelated_name of the model. And your QueueSerializer can inherit fromPrimaryKeyRelatedField to be rendered.

#models.py
class AlertModel(models.Model):
    ...
    queues = models.ManyToManyField(Queue, ... related_name='queues')     
    ...

#serializer.py
class QueueSerializer(PrimaryKeyRelatedField, serializers.ModelSerializer):
    class Meta:
       model: Queue

class AlertSerializer(serializers.ModelSerializer):
    queues = QueueSerializer(many=True, queryset=Queue.objects.all())

    class Meta:
        model = Alert
        fields = (
         'id', 'name', 'queues','email', 'expected_qos'
        )

What can I do ?

Not much since HTML form don't support nested serializers at the moment.

You could use a non nested relational field in the serializer to work this around or just use regular JSON.
