FAQ

Model instance is inferred as Any instead of my Model class

When subclassing ModelSerializer, add a type argument to type-hint the related model class, for example:

class MyModelSerializer(serializers.ModelSerializer[MyModel]):
    class Meta:
        model = MyModel
        fields = ("id", "example")

Which means that methods where the model is being passed around will know the actual type of the model instead of being Any. The instance attribute on the above serializer will be Union[MyModel, typing.Sequence[MyModel], None].
