Update DynamoDB Entry

I lookup to the docs, and there isn’t any way available to update a record already stored in dynamodb, which is kinda mandatory for me here.

I tried to update the attr value and then use replace!, but got nothing.

Does anyone knows a way for me to do this?

Thanks in advance

In fact seems that I haven’t payed enough attention to the docs… Here’s the way to update a record:

# given post is your record
post = post.replace(my_column: "new value")
