Question

Here is an example of StructuredProperty from the docs:

class Address(ndb.Model):
    type = ndb.StringProperty() # E.g., 'home', 'work'
    street = ndb.StringProperty()
    city = ndb.StringProperty()

class Contact(ndb.Model):
    name = ndb.StringProperty()
    addresses = ndb.StructuredProperty(Address, repeated=True)

guido = Contact(name='Guido',
                addresses=[Address(type='home',
                                   city='Amsterdam'),
                           Address(type='work',
                                   street='Spear St',
                                   city='SF')])

guido.put()

Imagine that Guido is temporarily in the city of Timbuktu, Mali for work. How would I go about retrieving and updating just his work address?

Thanks.

Answer 1

I’d try something like this.

for address in guido.addresses:
    if address.type == 'work':
        address.street = "Main Street"
        address.city = "Timbuktu"

guido.put()

EDIT
added a colon
