python - 如何检索和操作 ndb StructuredProperty 对象？

Question

这里是 StructuredProperty from the docs 的示例:

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()

假设 Guido 暂时在马里廷巴克图市工作。我该如何检索和更新他的工作地址？

谢谢。

Answer 1

我会尝试这样的事情。

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

guido.put()

编辑添加了一个冒号
