Question

how can I achieve this in google appengine db model

from google.appengine.ext import db
Class Car(db.Model):
    name=db.StringProperty()
    model=db.StringProperty()
    mileage=db.IntegerProperty()

Class Person(db.Model):
    name=db.StringProperty()
    age=db.IntegerProperty()
    cars=db.ListProperty(Car) # How can I have cars object for person containing list of Car Objects? 

Thank you

Answer 1

Have a look at the reference documentation http://code.google.com/appengine/docs/python/datastore/datamodeling.html#References

It works the other way round, class Car would have

person = db.ReferenceProperty(Person, collection_name="cars")

which would make a property cars available in Person.

Hope this helps.
