Laravel clone model

Created at 16-Dec-2022 , By samar

You can create a clone of model in Laravel using the replicate() method. You can get the model instance using find() method or you can also create a model instance using create() method after that you can create a new clone from that model using replicate() method.

Use below code to create a duplicate record in users table of Laravel application. You have to just place the code in your controller's method. It will create an another record in your users table.

User::find($id)->replicate()->save();

You can also clone a record to another table when you have model instances that share many of the same attributes. You may create an unsaved copy of an existing model instance using the replicate method and save to another model.

Here we have an address model and we have created a record in addresss table using create() method and after that we have created a duplicate record from it using replicate() method and update the "type" column value with "billing" and save the record in billing table.

$shipping = Address::create([
    'type' => 'shipping',
    'line_1' => '123 Example Street',
    'city' => 'Victorville',
    'state' => 'CA',
    'postcode' => '90001',
]);
 
$billing = $shipping->replicate()->fill([
    'type' => 'billing'
]);
 
$billing->save();
