[FIXED] Separate a relationship from the collection on Laravel 8 - Eloquent

Issue

I am generating a query that collects an invoice, and the related invoice customer.

$invoice = Invoice::with(['lines', 'fullClient'])->findOrFail($idInvoice);     
return view('invoiceView', ['invoice'=>$invoice]);

It works correctly, through $invoice->clients, I can access the client. But I would like to be able to separate the client from the collection invoice. To send it through another variable. So that it looks something like this:

$invoice = Invoice::with(['lines', 'fullClient'])->findOrFail($idInvoice); 
//Some magic here
return view('invoiceView', ['invoice'=>$invoice,'client'=>$client]);

It is to take advantage of an invoice creation view (to be able to edit), which is expected by the $clients collection.
I have searched, to do this in the view, but it is not possible or it is not recommended.

I guess I could do something like thisbefore sending it to view:

$client = $invoice->customer

But then I would be sending it twice on view.

Solution

To unset the relationship from a model you can use unsetRelation($relation) method

$invoice = Invoice::with(['lines', 'fullClient'])->findOrFail($idInvoice); 
$client = $invoice->fullClient;

$invoice->unsetRelation('fullClient');

return view('invoiceView', ['invoice'=>$invoice,'client'=>$client]);
