   .. classmethod:: setdefault(cls, key, default, deserialize_json=False)

      Like a Python builtin dict object, setdefault returns the current value
      for a key, and if it isn't there, stores the default value and returns it.

      :param key: Dict key for this Variable
      :type key: str
      :param default: Default value to set and return if the variable
          isn't already in the DB
      :type default: Mixed
      :param deserialize_json: Store this as a JSON encoded value in the DB
          and un-encode it when retrieving a value
      :return: Mixed
