Recalculate default values on update

[darbio]

Is it possible to 'autoupdate' values which are set with a default using Attribute when the item is updated?

As an example, when I update location, the geohash property should also be updated. Currently this does not occur.

import { Attribute, Entity, INDEX_TYPE } from '@typedorm/common';
import ngeohash from 'ngeohash';

import { BaseEntity } from './entity';

@Entity<IncidentEntity>({
    name: 'incident',
    primaryKey: {
        partitionKey: 'INCIDENT#{{id}}',
        sortKey: 'INCIDENT#{{id}}',
    },
    indexes: {
        gsi1: {
            partitionKey: 'INCIDENT',
            sortKey: 'INCIDENT#{{id}}',
            type: INDEX_TYPE.GSI,
        },
        gsi2: {
            partitionKey: 'INCIDENT',
            sortKey: '{{status}}#{{geohash}}',
            type: INDEX_TYPE.GSI,
        },
    },
})
export class IncidentEntity extends BaseEntity {
    @Attribute({
        unique: true,
    })
    id: string;

    @Attribute()
    location: {
        latitude: number;
        longitude: number;
    };

    @Attribute<IncidentEntity>({
        default: (incident) => ngeohash.encode(incident.location.latitude, incident.location.longitude, 12),
    })
    geohash: string;

    @Attribute()
    status: string;
}

@darbio This is not supported currently.
This can actually be a good feature and can be easily implemented within the @Attribute decorator.

Converting this discussion to a feature request.
