Can a field be configured to always update on save?

[LucasBadico]

I'm using the mapper with this schema based aprouch.

Object.defineProperties(MyDomainModel.prototype, {
    [DynamoDbSchema]: {
        value: {
            phone: {
                type: 'Dictionary',
                memberType: embed(Phone)
            },
        },
    },
}); 

createdAt and updatedAt

I see that for the attr createdAt I can send a defaultProvider instruction with new Date(). In the same way to the v4 for generating a uuid.

There is a way to send a instruction for the mapper change the attr updatedAt every time? Like a forced provider.

Object.defineProperties(MyDomainModel.prototype, {
    [DynamoDbSchema]: {
        value: {
            createdAt: {
                type: 'Date',
                defaultProvider: () => new Date()
            },
        },
    },
}); 

version attribute

class MyDomainClass {
    @autoGeneratedHashKey()
    id: string;

    @rangeKey({defaultProvider: () => new Date()})
    createdAt: Date;

    @versionAttribute()
    version: number;
}

How to use this version attribute in the Object.defineProperties way?

Hey guys, do want me to post this questions in other place or I can keep throwing things here?

Asking questions here is fine.

When defining a schema, you can add a versionAttribute: true property to any number property at the top level of the document. There isn't currently a way to have a field update on every save, but I can see the use of such a feature.

Got it! I Will try. I was thinking on erase the updateAt from the local data and send it. Since the updateAt have a default provider the it Will be recriated. This could Work? Em qui, 12 de jul de 2018 às 20:43, Jonathan Eskew <notifications@github.com> escreveu:
