I have a workflow that creates a record inside of a DynamoDB table as part of a pipeline within AWS. The record has a primary key of the Code Pipeline job. Later in the pipeline I wanted to edit that object to append the status of resources created by this pipeline.
In order to do this, I created two functions. One that first returns the item from the table and the second that actually does the update and puts the updated item back into the table. Take a look at the code below and utilize it if you need to!
import boto3 from boto3.dynamodb.conditions import Key def query_table(id): dynamodb = boto3.resource('dynamodb') table = dynamodb.Table('XXXXXXXXXXXXXX') response = table.query( KeyConditionExpression=Key('PRIMARYKEY').eq(id) ) return response['Items'] def update_dynanmo_status(id, resource_name, status): dynamodb = boto3.resource('dynamodb') table = dynamodb.Table('XXXXXXXXXXXXX') items = query_table(id) for item in items: # Do your update here response = table.put_item(Item=item) return response
