[英]DynamoDB - putItem - Map with nested data types (NodeJS, aws-sdk)
All - I am working on a specific business requirement and with the lack of info on Google I thought I would stop here for some info: 全部 - 我正在制定一项特定的业务要求,而且Google上缺少信息,我想我会在这里停下来获取一些信息:
I am basically ingesting a CSV, converting it to a JSON Object and stuffing it into Dynamo. 我基本上是在提取CSV,将其转换为JSON对象并将其填充到Dynamo中。 The interesting part is, the data types of the row values jump between strings and numbers but I am unable to get this to work properly.
有趣的是,行值的数据类型在字符串和数字之间跳转,但我无法使其正常工作。
I am using Node and the aws-sdk and literally used the Amazon Docs to test this straight up and it still did not work, see below: 我正在使用Node和aws-sdk并逐字地使用亚马逊文档对此进行直接测试,但仍然无效,请参阅下文:
var params = {
TableName: foo,
Item: {
masterReportsUuid: uuidv4(),
reportDate: _eventDate,
"testAttribute": {
"Name": {
"S": "Joe"
},
"Age": {
"N": "35"
}
},
}
};
dbDocClient.put(params, (err, data) => {
if (err) {
//log to CloudWatch
console.log(err);
reject(err);
} else {
resolve(data);
}
});
The testAttribute obviously is a Map with Name and Age, string and number. testAttribute显然是一个包含Name和Age,字符串和数字的Map。 This is straight from the documentation -
这直接来自文档 -
https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB.html#putItem-property https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB.html#putItem-property
An attribute of type Map. Map类型的属性。 For example:
例如:
"M": {"Name": {"S": "Joe"}, "Age": {"N": "35"}} “M”:{“姓名”:{“S”:“Joe”},“年龄”:{“N”:“35”}}
But this outputs like this in Dynamo - 但这在Dynamo中输出如下 -
So my question is - why is this not working? 所以我的问题是 - 为什么这不起作用?
EDIT: Typos. 编辑:错别字。
Ugh - I fixed the issue. 呃 - 我解决了这个问题。 I will leave this here in case anyone runs into this.
如果有人碰到这个,我会留在这里。
Two Issues - I was using the DynamoDB.DoucmentClient().put API Call and not the DynamoDB.putItem call AND my params object was close but not correct. 两个问题 - 我正在使用DynamoDB.DoucmentClient()。放置API调用而不是DynamoDB.putItem调用AND我的params对象是关闭但不正确。 Please see below for a working example of nested Map AttributeTypes -
请参阅下面的嵌套Map AttributeTypes的工作示例 -
const dbDocClient = new aws.DynamoDB.DocumentClient();
const dbDynamo = new aws.DynamoDB();
var params = {
TableName: _ReportsTable,
Item: {
testUuid: {
"S": uuidv4()
},
testDate: {
"S": _eventDate
},
testAttribute: {
"M": {
"Name": {
"S": "Joe"
},
"Age": {
"N": "35"
}
}
},
}
};
dbDynamo.putItem(params, (err, data) => {
if (err) {
//log to CloudWatch
console.log(err);
reject(err);
} else {
resolve(data);
}
});
