Default Values ​​for Models in the Google App Engine

Question

Can I set default values ​​for models? For example, view this model from the Appengine documentation.

from google.appengine.ext import db class Pet(db.Model): name = db.StringProperty(required=True) type = db.StringProperty(required=True, choices=set(["cat", "dog", "bird"])) birthdate = db.DateProperty() weight_in_pounds = db.IntegerProperty() spayed_or_neutered = db.BooleanProperty() owner = db.UserProperty(required=True) 

I want to set the default value of name to "Untitled", so if the user does not provide it, the default values ​​are accepted. So is this possible?

PS: I want this to be done in the Pet model class itself

Answer 1

Use the default attribute, e.g.

 class Pet(db.Model): name = db.StringProperty(required=True, default="(unnamed)")
