'Unset/Remove relation object from Laravel Eloquent collection

I've a fetch a Laravel Eloquent collection by:

$product = Product::query()->with(['merchant', 'picture'])->where('id', $id)->first();

and get the dump of $product is

Product {
  #casts: ...
  #dates: ...
  #connection: "mysql"
  #table: null
  #primaryKey: "id"
  #keyType: "int"
  +incrementing: true
  #with: []
  #withCount: []
  #perPage: 15
  +exists: true
  +wasRecentlyCreated: false
  #attributes: array:1 [
    "id" => 27
  ]
  #original: ...
  #changes: []
  #dateFormat: null
  #appends: []
  #dispatchesEvents: []
  #observables: []
  #relations: array:2 [
    "merchant" => Merchant {...}
    "picture" => Picture {...}
    }
  ]
  #touches: []
  +timestamps: true
  #hidden: []
  #visible: []
  #fillable: []
  #guarded: ...
}

I need to unset the relation object merchant and picture from this collection.

I've tried following options but failed:

unset($product['merchant']);
unset($product->merchant);

Any help will be appreciate.

Thanks in advance

In Laravel 5.6.25, you can use unsetRelation():

$product->unsetRelation('merchant')->unsetRelation('picture');

Before that:

$relations = $product->getRelations();
unset($relations['merchant'], $relations['picture']);
$product->setRelations($relations);

I have to tables with the same fields.. So I need to check the different column based on value. So if the value of foreign key is same then need to unset that relation

If you have merchant property in the model (merchant column in the table) you can get it value using $product->getOriginal('merchant') or $product->getAttribute('merchant')

Solution 3:[3]

you can unset it

unset($product->merchant);
