[BUG] Inconsistent items are generated when an item is created and when an item is fetched from the database

Summary:

When creating a new item using a model the field aliases are not accessible. When fetching an item the main field itself is not accessible only its alias is.

Disclaimer: I have only tried this in dynamodb local and with dynamoose v3 so can’t say if this is the expected behavior or is bug. It was suggested in Slack that ticket is created https://dynamoose.slack.com/archives/CG4B7RL8N/p1661138601979229

Code sample:

    const User = dynamoose.model("User", {"pk": {"type": String, "alias": "email"}});
    new dynamoose.Table("User", [User]);

    const user1 = await User.create({ "email": "[e-mail]" })
    const user2 = await User.create({ "pk": "[e-mail]" })

    console.log(user1, user1.email) // User { pk: '[e-mail]' } undefined
    console.log(user2, user2.email) // User { pk: '[e-mail]' } undefined

    const user3 = await User.get('[e-mail]')
    console.log(user3, user3.pk) // User { email: '[e-mail]' } undefined

Current output and behavior (including stack trace):

The current output is inlined in the code example above

Expected output and behavior:

The expected behavior is for Model.create() and Model.get() generate consistent items. Both the DDB field and the alias should be accessible in the generated items.

Environment:

Operating System: Ubuntu Operating System Version: 20.04.2 LTS Node.js version (node -v): v14.19.0 NPM version: (npm -v): 8.6.0 Dynamoose version: 3.0.0

try to include mapAttributes: true

Beautiful! Thank you @hpinheiro-godaddy! Using mapAttributes: true works 👍.

I removed some of the other settings that I don’t know what they do ended up with this:

    console.log(await item.conformToSchema({     
      mapAttributes: true,      
      modifiers: ["get"],
      type: "fromDynamo"
    }))
