python - Rename deseralized fields in Colander -

i'm using colander convert json strings python objects , vice versa in pyramid/cornice based project.

is there way can serialize/deserialize different names/keys ?

here colander schema:

class commentschema(mappingschema):     resource_id = schemanode(int(), name="resourceid", location="body")     text = schemanode(string(), name="text", location="body") 

and here input json

{"text":"hello!", "resourceid":12} 

it being converted :

{u'text': u'hello!', u'resourceid': 12} 

here question, can have same input json converted following?

{u'full_text': u'hello!', u'resource_id': 12} 

thanks help.

i had manually. whatever received json used construct data object. object have custom function map data desired output format, , pass output serializer:

data_schema = dataschema().deserialize(self.request.json) data_obj = dataobject(data_schema**) // or dataobject(full_text = data_schema['text'], resource_id = data_schema['resourceid']) # # ... # rbody = dataschema().serialize(data_obj.map_dump()) return response(body=rbody, status_code=201) 

and dataobject this:

class profileobj(object):      def __init__(self, text, resourceid):  // or __init__(self, full_text, resource_id)         self.text = text         self.resourceid = resourceid      def map_dump(self):         output['full_text'] = self.text         output['resource_id'] = self.resource         return output
