Python - Bulbs - Models - Class initialization

Question

I'm learning how to use Bulbs models, I have questions on Node classes initialization.

From the documentation:

from bulbs.model import Node, Relationship
from bulbs.property import String, Integer, DateTime
from bulbs.utils import current_datetime

class Person(Node):

    element_type = "person"

    name = String(nullable=False)
    age = Integer()

How can I perform data manipulation before saving the data in the node?

Can I perform something like

class Person(Node):

    element_type = "person"

    name = String(nullable=False)
    if name == "Bar":
        name = "Foo"

Or I have to override the Node init?

class Person(Node):

    element_type = "person"

    name = String(nullable=False)

    def __init__(self, name):
        if name == "Bar":
            self.name = "Foo"

Answer 1

Override the model's _create() method.
