You need to define that method in your class:
def votes_up
self[:votes_up]
end
Or you have to use to_json(:except=>:votes_up) to not include the
column in the JSON output.
It's fairly trivial to modify the json_serializer plugin to just use
the value in the values hash if it doesn't respond to the method. I'm
not sure that's a good idea, though. For stuff like this, it's often
easier to use plain hashes instead of model objects.
