Dyno.py

A python client designed to work with AWS DynamoDB following the SingleTable schema model.

Ops

PutItem

This operation requires a partition key and optionally a sort key.

fromdypy.dbimportSingleItemimportuuiditem=SingleItem(pk='user@email.com', sk=uuid.uuid4().hex, name='Frank')

Create a new Table instance, call the put method passing the SingleItem object to execute the operation.

...
response=Table('TableName').put(item)

Use the ok attribute to validate if the request was successful.

...
ifresponse.ok:
print("Item saved", item.data())

Secure PutItem

The SecureItem prevents items overwriting.

fromdypy.dbimportSecureItemitem=SecureItem(pk='user@email.com', sk=uuid.uuid4().hex, name='Frank')
response=Table('TableName').put(item)
