If your Laravel Model needs access to repository for pulling relationship data, think again.
It’s the wrong way round, don’t do it. Your models need access to data without any N+1 issues from using Lazy load. So if you need to merge some data streams and return a collection, rather than use a repo call to access each stream object; Create a view table which `Union ALL`’s the data various models. Then the model can have lazy load access to all the things you need, and the laravel commands, `->with()` or `->load()` can work without slowing it all down
