Description

Not sure if this is a bug report of enhancement but I can only select bug report for documentation, so here it goes. I'm trying to use MessageSigning with custom serializers. I have a single object type that is being returned by the tasks which I cannot change. For that object type I've added a JSONEncoder and a JSONDecoder, which are registered as:

from kombu.serialization import register register('task-result', lambda obj: json.dumps(obj, cls=TaskResultEncoder), lambda jst: json.loads(jst, cls=TaskResultDecoder), content_type='application/x-task-result', content_encoding='utf-8')

Now, the message signing section of the Security documentation explains well how to set things up with the default json serializer. There's no word if it's possible to set custom serializers? Possibly through the serializer kwarg of setup_security? Now, I tried that, and it didn't work it still uses the buildin json serializer and whenever a TaskResult instance should be serialized I get a TypeError stating it's not serializable. Disabling MessageSigning solves the issue, but oh well I thought I might just ask.

Suggestions

Can you include these tiny bits in the documentation? There's a section for serializers, there's another section for MessageSigning but nothing regarding how to use those things together? I mean with custom serializers obviously.
