Yes, you can use the setRelation method on the Sale model to set the relationship with the existing collection of Representative models. Here's an example:
// Assume we have loaded all Representative models into a $representatives collection
$representatives = Representative::all();
// Load all Sale models with the representatives relationship
$sales = Sale::with('representatives')->get();
// Loop through each Sale model and set the representatives relationship using the existing collection
$sales->each(function ($sale) use ($representatives) {
$representative = $representatives->where('id', $sale->representative_id)->first();
$sale->setRelation('representatives', $representative);
});
In this example, we first load all Representative models into a collection. Then, we load all Sale models with the representatives relationship using Sale::with('representatives')->get(). Finally, we loop through each Sale model and use the setRelation method to set the representatives relationship using the existing collection of Representative models.
Note that this approach assumes that the representative_id column on the Sale model matches the id column on the Representative model. If they have different names, you'll need to adjust the code accordingly.
