Make it possible to set dataKey to a Promise

[devdaniero]

I'm currently working on a project which uses TypeORM and jsonapter to retrieve and expose a product feed. The product entity is very large and therefore some relations are set to lazy. This wraps the field into a Promise.

Unfortunately when I use the lazy loaded field in a template I can't seem to get it working. The output is omitted and when I log the value it's still resolving the Promise.

Is it possible to implement Promise compatibility here? Or what workaround can I use to be able to pass resolved fields to jsonapter engine?

Template snippet where regularPrice is a lazy loaded field.
content: { ... regularPrice: { dataKey: 'regularPrice', template: priceTemplate }, ... }

The priceTemplate contains another content block with more fields.

That is not a quick fix and at least I will not have cycles in very near future.

I managed to work around it by wrapping my Product entity and declaring the lazy loaded fields as separate fields. Something like this:

class View {
    product: Product;
    regularPrice: Price;
    currentPrice: Price;
    // ... Omitted getters and setters
}

Instead of passing Product[] as payload I transform it to the View class by just setting the Product as is and assign the lazy loaded fields after calling await on them.

let view: View = new View();
view.product = product;
view.regularPrice = await product.regularPrice; // Omitted null check
view.currentPrice = await product.currentPrice; // Omitted null check
