Eager load relationship

If you use Route Model Binding and think you can't use Eager Loading for relationships, think again.

So you use Route Model Binding

public function show(Product $product) {
    //
}

But you have a belongsTo relationship, and cannot use $product->with('category') eager loading?

You actually can! Load the relationship with ->load()

public function show(Product $product) {
    $product->load('category');
    //
}
