The get_resource_type_from_serializer bug

[EmilTemirov]

django-rest-framework-json-api v2.0.0-beta.2
I have defined resource_name attribute into Meta class of my serializer:

class MySerializer(serializers.Serializer):
    email = serializers.EmailField(required=True)
    class Meta:
        resource_name = 'user'

In this case the get_resource_type_from_serializer will always raise AttributeError, because there isn't defined the model attribute.
Code of get_resource_type_from_serializer:

def get_resource_type_from_serializer(serializer):
    return getattr(
        serializer.Meta,
        'resource_name',
        get_resource_type_from_model(serializer.Meta.model))
