Including and excluding properties when using the collect() method?

[jonjakoblich]

How can I include a Lazy property on when creating a collection of data objects?

I understand from the docs that this works (assume property 'name' is Lazy).

SongData::from(Song::first())->include('name');

But, because this returns a Collection, the following code will not work.

SongData::collect(Song::all())->include('name');

What ae my options for including Lazy properties with collections? I am working with v4. Thanks!

Since collect outputs the same type as it gets fed, the following:

SongData::collect(Song::all())->include('name');

Will return an Eloquent collection which doesn't support includes. Try the following:

SongData::collect(Song::all(), DataCollection::class)->include('name');

Thank you! Would this be the same for only() and except() also? Do the properties have to be Lazy for only() and except() to work?

Jup same thing, they don't have to be lazy and get executed before we evaluate lazy.
