How to access function defined in a class?

[AvadootNachankar]

///////////////////////////////////////////////////////////////////////////////////////////////// @connection.register

class Author(DjangoDocument): collection_name = 'Authors' structure = { 'name': unicode, 'created_at': datetime.datetime }

required_fields = ['name']
default_values = {'created_at':datetime.datetime.utcnow}

use_dot_notation = True

def my_func(self):
    print(" my_func working...\n")

/////////////////////////////////////////////////////////////////////////////////////////////////

in shell, i.e. "python manage.py shell"

from .models import * from django_mongokit import get_database from bson import ObjectId

db = get_database()

c_author = db[Author.collection_name]

o_author = c_author.Author()

o_author {'created_at': datetime.datetime(2013, 9, 16, 9, 51, 43, 200898), 'name': None}

o_author.my_func() Traceback (most recent call last): File "", line 1, in File "/home/tissavadoot/Desktop/Tissproject/TP_MK/local/lib/python2.7/site-packages/mongokit/schema_document.py", line 379, in getattr return dict.getattribute(self, key) AttributeError: 'Author' object has no attribute 'my_func'
