PynamoDB -如何使用扫描(attributes_to_get=[...])

from pynamodb.models import Model
from pynamodb.attributes import UnicodeAttribute

class MyModel(Model):
    class Meta:
        table_name = 'my_table'
        region = 'us-west-2'  # 设置所在地区
        aws_access_key_id = 'your_access_key_id'  # 设置访问密钥ID
        aws_secret_access_key = 'your_secret_access_key'  # 设置访问密钥

    # 定义模型的属性
    id = UnicodeAttribute(hash_key=True)
    name = UnicodeAttribute()

# 创建模型实例
model = MyModel()

# 执行扫描操作
scan_result = model.scan(attributes_to_get=['id', 'name'])

# 处理扫描结果
for item in scan_result:
    print(item.id, item.name)
