下面的代码可以工作,但保存到 us-east-1 区域。我如何将其保存到 us-west-1 ?我已经挖掘了 Pynamodb 的源代码,但没有找到正确的方法。
from pynamodb.models import Model
from pynamodb.indexes import GlobalSecondaryIndex, AllProjection
from pynamodb.attributes import UnicodeAttribute, NumberAttribute
class DaysIndex(GlobalSecondaryIndex):
"""
This class represents a global secondary index
"""
read_capacity_units = 2
write_capacity_units = 1
projection = AllProjection()
days_old = NumberAttribute(hash_key=True)
class HackerNewsLinks(Model):
"""
A test model that uses a global secondary index
"""
table_name = 'HackerNews'
link = UnicodeAttribute(hash_key=True)
title = UnicodeAttribute()
days_index = DaysIndex()
days_old = NumberAttribute(default=0)
if not HackerNewsLinks.exists():
HackerNewsLinks.create_table(read_capacity_units=1, write_capacity_units=1, region='us-west-1')
hn_item = HackerNewsLinks('http://www.blah.com', title='forum_subject', days_old=10)
hn_item.save()
# Indexes can be queried easily using the index's hash key
for item in HackerNewsLinks.days_index.query(1):
print("Item queried from index: {0}".format(item))

我刚刚在 0.1.12 版本中为 PynamoDB 模型 API 添加了区域支持,您介意升级并重试吗?
语法如下:
class HackerNewsLinks(Model):
"""
A test model that uses a global secondary index
"""
class Meta:
region = 'us-west-1'
table_name = 'HackerNews'
link = UnicodeAttribute(hash_key=True)
title = UnicodeAttribute()
days_index = DaysIndex()
days_old = NumberAttribute(default=0)
