talk_with_dynamo

A class that provides functionality for interacting with AWS DynamoDB tables. It allows you to perform various operations like querying, getting items, updating, inserting, deleting, and scanning the table.

class talk_with_dynamo(table, boto_session, region='us-east-1')

Example:
    table_name = "table-name"
    boto_session = boto3.session.Session()
    dynamo = talk_with_dynamo(table_name, boto_session) # Generate Database Object

    response = dynamo.query(partition_key, partition_key_attribute, sorting_key=False, sorting_key_attribute=False, index=False, queryOperator=False, betweenValue=False)
    print("Response: {}".format(response))

    getResponse = dynamo.getItem(partition_key, partition_key_attribute, sorting_key=False, sorting_key_attribute=False)

    batch_keys = {'tableName': {'Keys': [{'PartitionKey': 'PartitionKeyAttribute', 'SortingKey': 'SortingKey'}]}}
    batchResponse = dynamo.batchGetItem(batch_keys)

    insert_response = dynamo.insert(json_object)
    print("Insert Response: {}".format(insert_response))

    update_response = dynamo.update(partition_key_attribute, sorting_key_attribute, update_key, update_attribute)

    update_response = dynamo.updateV2(partition_key_attribute, update_key, update_attribute, sorting_key_attribute=None)

    delete_response = dynamo.delete(partition_key_attribute, sorting_key_attribute=False, sorting_key=None, partition_key=None)

    scan_results = dynamo.scan(filter_expression=None, expression_attribute_values=None)

    dynamo.clearTable() # Delete all entries in a table -- Use with caution

extractDynamoDBData

Extracts and cleans data from a payload retrieved from DynamoDB.

Parameters:

• payload (dict): The payload containing data retrieved from DynamoDB as a dictionary.
• record (str): The key to access a specific piece of data within the payload.
• dataType (str, optional): The type of data to retrieve. Default is "S" (string).

Returns:

• str or int or False: The extracted and cleaned data based on the specified record and dataType.
• Returns False if the specified record is not found, or if there is an error during data extraction.

function extractDynamoDBData(payload, record, dataType="S")

Example:
    payload = {
        "name": "John Doe",
        "age": {
            "N": "30"
        },
        "address": "123 Main Street"
    }
    data = returnData(payload, "name")
    print(data)  # Output: "John Doe"

    data = returnData(payload, "age", dataType="N")
    print(data)  # Output: 30

    data = returnData(payload, "email")
    print(data)  # Output: False (record not found in payload)

        Functions:
            get_secret(secret_name)
            - Returns decoded secret from AWS Secrets Manager
