Using djangorestframework2 to get JSON given just a resource outside of a view

gistfile1.py

from djangorestframework.renderers import JSONRenderer

from colorpicks.serializer import ColorSerializer
# NOTE: Resources are nominally much less present in the
#       restframework2 branch.  You use Serializers directly
#       to achieve the same thing.

obj = ...
serializer = ColorSerializer(instance=obj)
data = serializer.data

jsonr =  JSONRenderer()
json_string = jsonr.render(data)
