python-3.x - Flask Dynamo连接问题(AttributeError:“Dynamo”对象没有属性“tables”)

from flask import Flask
from flask_dynamo import Dynamo
import os
os.environ['AWS_ACCESS_KEY_ID'] = ''
os.environ['AWS_SECRET_ACCESS_KEY'] = ''
os.environ['AWS_REGION'] = 'ap-south-1'
app = Flask(__name__)
app.config['DYNAMO_TABLES'] = [
{
    'TableName': 'users',
    'KeySchema': [dict(AttributeName='username', KeyType='HASH')],
    'AttributeDefinitions': [dict(AttributeName='username', AttributeType='S')],
    'ProvisionedThroughput': dict(ReadCapacityUnits=5, WriteCapacityUnits=5)
}, {
     'TableName': 'groups',
    'KeySchema': [dict(AttributeName='name', KeyType='HASH')],
    'AttributeDefinitions': [dict(AttributeName='name', AttributeType='S')],
    'ProvisionedThroughput': dict(ReadCapacityUnits=5, WriteCapacityUnits=5)
}
      ]
app.config['DYNAMO_ENABLE_LOCAL'] = True
app.config['DYNAMO_LOCAL_HOST'] = 'localhost'
app.config['DYNAMO_LOCAL_PORT'] = 9000
dynamo = Dynamo()

当我尝试获取创建所有表时，已定义flask-dynamo的表配置并创建了dynamo实例，获取内置表错误。AttributeError AttributeError：'Dynamo'对象没有属性'tables'

@app.route('/', methods=['GET'])
def hello_world():
    with app.app_context():
        dynamo.create_all()
    return 'table created!'

提前致谢

最佳答案

这行：

dynamo = Dynamo()

应该：

dynamo = Dynamo(app)

这样，dynamo实例可以访问您在app对象上定义的表和其他配置。
