尝试使用flask-dynamo got error“”
在Dynamo db中创建包含三个字段的表botocore.exceptions.ClientError botocore.exceptions.ClientError:调用CreateTable操作时发生错误(ValidationException):密钥模式中的属性数必须与属性定义中定义的属性数相匹配
这里是配置create table dynamo db
@app.route('/create_table')
def create_table():
app.config['DYNAMO_TABLES'] = [
{
'TableName': "user_detail",
'KeySchema': [
{'AttributeName': "timestamp", 'KeyType': "HASH"},
{'AttributeName': "question", 'KeyType': "RANGE"},
],
'AttributeDefinitions': [
{'AttributeName': "timestamp", 'AttributeType': "S"},
{'AttributeName': "question", 'AttributeType': "N"},
{'AttributeName': "user", 'AttributeType': "N"},
],
'ProvisionedThroughput': {
'ReadCapacityUnits': 40,
'WriteCapacityUnits': 40
}
}]
dynamo = Dynamo(app)
with app.app_context():
dynamo.create_all()
return "Table created"
提前致谢
答案 0 :(得分:2)
您需要删除以下行:
Actions action = new Actions(driver);
action.MoveToElement(driver.FindElement(By.XPath("//div[@id='new_lookupid']/div[1]"))).
ClickAndHold().Release().Click().Perform();
IWebElement typeIntoLookup= driver.FindElement(By.XPath("//input[@id='new_lookupid_ledit']"));
//send keys
typeIntoLookup.SendKeys("ElementofLookup"); //the lookup text
使用DynamoDB(与大多数NoSQL数据库一样),您不需要提前指定每个记录属性字段。您只需要提前指定哈希和范围字段。
