Methods

add_adapter(type_or_iface, adapter)	When an object of the type (or interface) type_or_iface fails to automatically encode using the serializer, the renderer will use the adapter adapter to convert it into a JSON-serializable object.
datetime_adapter(obj, request)
decimal_adapter(obj, request)

add_adapter(type_or_iface, adapter)

When an object of the type (or interface) type_or_iface fails to automatically encode using the serializer, the renderer will use the adapter adapter to convert it into a JSON-serializable object. The adapter must accept two arguments: the object and the currently active request.

class Foo:
    x = 5

def foo_adapter(obj, request):
    return obj.x

renderer = JSON(indent=4)
renderer.add_adapter(Foo, foo_adapter)

When you’ve done this, the JSON renderer will be able to serialize instances of the Foo class when they’re encountered in your view results.
