Sorry for self-advertisement, but I've wrote a small utility to solve this kind
of problems -- jsonpublish[1]. Code looks like this:
class Base(object):
pass
from jsonpublish import register_adapter, dumps
@register_adapter(Base)
def adapt_base(b):
return {} # adapt Base object to json-encodable structure
dumps(Base()) # now it works!
See docs[1] for more info.
