Answer 1

heyy

from pymongo.son_manipulator import SONManipulator

class Transform(SONManipulator):

  def transform_incoming(self, son, collection):

    for (key, value) in son.items():

      if isinstance(value, Custom):

        son[key] = encode_custom(value)

      elif isinstance(value, dict): # Make sure we recurse into sub-docs

        son[key] = self.transform_incoming(value, collection)

    return son

  def transform_outgoing(self, son, collection):

    for (key, value) in son.items():

      if isinstance(value, dict):

        if "_type" in value and value["_type"] == "custom":

          son[key] = decode_custom(value)

        else: # Again, make sure to recurse into sub-docs

          son[key] = self.transform_outgoing(value, collection)

    return son...
