Cannot specify extra arguments when deserializing.

[johnnyleitrim]

I wrote my own custom serializer. I can pass my Serializer parameters when I make a call to it:

serializers.serialize("my_format", queryset, my_param = my_value)

I can get the value of my_param in my Serializer class.

However, I cannot do the same when deserializing. This is because the deserialize method in django.core.serializer.__init__.py does not accept any extra parameters:

    def deserialize(format, stream_or_string):
        """
        Deserialize a stream or a string. Returns an iterator that yields ``(obj,
        m2m_relation_dict)``, where ``obj`` is a instantiated -- but *unsaved* --
        object, and ``m2m_relation_dict`` is a dictionary of ``{m2m_field_name :
        list_of_related_objects}``.
        """
        d = get_deserializer(format)
        return d(stream_or_string)

I think that this should be changed to allow for optional parameters:

    def deserialize(format, stream_or_string, **options):
        """
        Deserialize a stream or a string. Returns an iterator that yields ``(obj,
        m2m_relation_dict)``, where ``obj`` is a instantiated -- but *unsaved* --
        object, and ``m2m_relation_dict`` is a dictionary of ``{m2m_field_name :
        list_of_related_objects}``.
        """
        d = get_deserializer(format)
        return d(stream_or_string, **options)
