I’m trying to make use of an existing table in my stack because despite using a PolicyStatement in my stack that looks like this:

new PolicyStatement({
      actions: ['dynamodb:*'],
      effect: Effect.ALLOW,
      resources: [
        'arn:aws:dynamodb:eu-west-2:12345667889:table/mytable/*',
        'arn:aws:dynamodb:eu-west-2:12345667889:table/mytable',
      ],
    });

I’m still getting an error about not having the permission to PutItem so I wanted to try adding consumers to a table construct instead but I don’t quite understand the sample. From the doc here it shows:

import { Table } from "@aws-cdk/aws-dynamodb";

new Table(this, "Table", {
  dynamodbTable: Table.fromTableArn(stack, "MyDynamoDBTable", tableArn),
});

Is this something i need to do from within my SST stack? If so, what is

stack

referencing?

Sorry are you not able to adding the PutItem permission to the existing table? Or are you looking for an example of adding consumers?

I want my lambda to have PutItem permission to a table that has already been defined within AWS

Say u r importing a table like this:

import dynamodb from "@aws-cdk/aws-dynamodb";

const existingTable = dynamodb.Table.fromTableArn(this, "ImportedTable", tableArn);
const table = new sst.Table(this, "MyTable", {
  dynamodbTable: existingTable,
});

You can grant the permission like this:

const fn = new sst.Function(this, "MyFunction", ...);
fn.attachPermissions([table]);

And similarly u can grant the permission to all function in an api like this:

const api = new sst.ApiGatewayV1Api(this, "MyApi", ...);
api.attachPermissions([table]);

Cool - I’ll give that a try - the docs are very slightly different, they have new Table(this, “Table”, { dynamodbTable: Table.fromTableArn(stack, “MyDynamoDBTable”, tableArn), });

Yeah.. i think the two `Table`s in the snippet is confusing… and where that

stack

comes from..

Cool - that worked too, thanks again.

👍 Thanks for pointing it out
