我正在尝试S3通过aws-sdk我的 lambda 函数进行访问。
import S3 from 'aws-sdk/clients/s3';
const s3 = new S3();
const { Contents: results } = await s3.listObjects({ Bucket: process.env.DOCUMENTS_BUCKET_NAME! }).promise()
我也使用命令成功部署了它cdk deploy。但是当我测试时，我收到以下错误

File "migration/env.py", line 55, in run_migrations_online

ImportError: No module named configuration
我尝试了请求一个简单的alembic工作示例中提到的自动生成迁移的解决方案,但它对我不起作用
我env.py run_migrations_online()改变的方法是
def run_migrations_online():
"""Run migrations in 'online' mode.
In this scenario we need to create an Engine
and associate a connection with the context.
"""
import os
import sys
sys.path.append(os.getcwd())
from configuration …很抱歉这不是编程问题,但当我试图反省我的类对象时,这引起了我的注意.
我找到了这个
{'user_id': 1, '_state': <django.db.models.base.ModelState object at 0x10ac2a750>, 'id': 2, 'playlist_id': 8}
角色是_state什么,有什么ModelState作用？
该文档没有给出任何关于它的想法.
我的REST观点可能会引发错误
$scope.delete = function(index) {
Transaction.delete({transactionId: $scope.transactions[index].uuid})
};
我把上面改为以下
$scope.delete = function(index) {
Transaction.delete({transactionId: $scope.transactions[index].uuid})
.success('transaction deleted');
};
但它失败了
TypeError: Object #<Resource> has no method 'success'

我该如何处理success和error场景？
